# Phase boundaries
|
||||
|
||||
A **phase** is a chunk of work inside a session: the grilling, the implementation, the QA. The definition is fuzzy on purpose: a phase ends when you think *"ok, we're done with that"*.
|
||||
|
||||
The **phase boundary** is the gap between two phases, and it is the only place this decision belongs. Mid-phase there is no decision to make: continue, or split the work that's left into subagents. Compacting mid-phase makes the agent lose the thread.
|
||||
|
||||
## The five options
|
||||
|
||||
| Option | What it does |
|
||||
| ------------ | --------------------------------------------------------------- |
|
||||
| **Continue** | Stay in the session. No context switch at all. |
|
||||
| **`/clear`** | Empty the context window and start from nothing. |
|
||||
| **`/handoff`** | Write a portable markdown file and seed a session anywhere with it. |
|
||||
| **Subagent** | Send the task to its own context window and get a report back. |
|
||||
| **`/compact`** | Compress this context and seed a fresh session with the summary. |
|
||||
|
||||
## The tree
|
||||
|
||||
Work top to bottom at the boundary. The first **yes** wins.
|
||||
|
||||
**1. Can you continue in this session?** Two things make the answer yes: the next phase needs this phase as a **primary source**, or you have enough [smart zone](https://www.aihero.dev/ai-coding-dictionary/smart-zone) left (~150k tokens) for the next phase to fit. Grilling → implementation is the standard yes: the implementation wants the reasoning verbatim, not a summary of it. Continue costs nothing and loses nothing, so rule it out before anything else.
|
||||
|
||||
**2. Is the context irrelevant to what comes next?** Is everything in this session (the exploration, the decisions, the dead ends) disposable? If so, **`/clear`**. It is the cheapest move on the board: it takes no time and hands back the whole window. `/clear` also isn't terminal: the old session stays resumable.
|
||||
|
||||
The cost of getting this wrong is one-way. Clear a *relevant* context and you lose the **why** behind what you built, and no amount of reading the diff back gets it returned.
|
||||
|
||||
**3. Do you need to hand off?** `/handoff` is narrow. You need it only when you are:
|
||||
|
||||
- swapping to a **new harness** (Claude → Codex),
|
||||
- moving to a **new directory** or repo,
|
||||
- sending the work to a **colleague**,
|
||||
- or forking a side task you found **mid-phase** without derailing what you're doing.
|
||||
|
||||
That list is the whole clause. What `/handoff` buys is **portability**: a file that travels. If nothing is travelling, you don't need it.
|
||||
|
||||
**4. Can the task be done AFK?** Is it scoped tightly enough to run with you away from the keyboard, no steering? Then send it to a **subagent** and leave this session untouched. Automated review is the standard case: the agent reads the diff and reports, and you aren't needed while it does.
|
||||
|
||||
**5. Otherwise, `/compact`.** Relevant context, same harness, same directory, and you need to stay in the loop: this is where the tree lands, and it lands here often. Pass it an instruction (`/compact we're going to QA this area`) so the summary keeps what the next phase needs.
|
||||
|
||||
`/compact` is the **default, not the first reach**. It sits at the bottom because the four questions above it are all cheaper or more precise. The failure mode when people start here is a fresh session that is confidently wrong about a decision the summary flattened.
|
||||
|
||||
## Primary and secondary sources
|
||||
|
||||
Every move except **Continue** turns a **primary source** into a **secondary source**: the session as it happened, replaced by a summary of it. The trade is always the same shape:
|
||||
|
||||
| Source | Information | Noise | Room to move |
|
||||
| --------------------------------- | ----------- | ----- | ------------ |
|
||||
| Primary (Continue) | Full | Lots | Little |
|
||||
| Secondary (`/compact`, `/handoff`) | Lossy | Less | Lots |
|
||||
|
||||
This is why question 1 comes first. You only pay the lossiness when staying costs more than it saves.
|
||||
|
||||
## These are judgement calls
|
||||
|
||||
The questions are not objective: each has taste in it, and the same boundary can go two ways on two days. The value is in asking them **in order**, at the boundary rather than in the middle of the work.

# Ask Matt
|
||||
|
||||
You don't remember every skill, so ask.
|
||||
|
||||
Before stating what a skill does or recommending a step be skipped, read that skill's SKILL.md: the summaries here are for orientation only.
|
||||
|
||||
A **flow** is a path through the skills. Most paths run along one **main flow**, and two **on-ramps** merge onto it. Everything else is standalone, or a vocabulary layer that runs underneath.
|
||||
|
||||
## The main flow: idea → ship
|
||||
|
||||
The route most work travels. You have an idea and want it built.
|
||||
|
||||
1. **`/grill-with-docs`** sharpens the idea by interview. Start here whenever you are **working in a working directory**: it's stateful, retaining what it learns in `GLOSSARY.md` and ADRs. (No working directory? Use `/grill-me` instead, covered under Standalone. Both run the same `/grilling` primitive; `grill-with-docs` is the one that leaves a paper trail, which makes it the better of the two whenever a repo is there to leave it in.)
|
||||
2. **Branch: can you settle every question in conversation?** If a question needs a runnable answer (state, business logic, a UI you have to see), detour through a prototype, bridged by **`/handoff`** in both directions (a prototype lives in its own directory, which is exactly what `/handoff` is for; see Phase boundaries):
|
||||
- **`/handoff`** out, then open a fresh session against that file,
|
||||
- **`/prototype`** to answer the question with throwaway code,
|
||||
- **`/handoff`** back what you learned, and reference it from the original idea thread.
|
||||
3. **Branch: is this a multi-session build?**
|
||||
- **Yes** → **`/to-spec`** (turn the thread into a spec), then **`/to-tickets`** to split it into tracer-bullet tickets, each declaring its **blocking edges**. Then work the tickets one of two ways:
|
||||
- **`/implement`** per ticket, **`/clear`ing context between each one**. On a local tracker that's one file per ticket under `.scratch/<feature>/issues/`, worked blockers-first by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed. Each ticket is self-contained, so the last one's context is disposable.
|
||||
- **`/implement-spec`** for the whole spec in one run. It reads the tickets as a **task graph**, runs implementer subagents across the ready **frontier** in parallel, and lands everything on one **integration branch**. Reach for it when you'd rather orchestrate the build than drive each ticket yourself.
|
||||
- **No** → **`/implement`** right here, in the same context window.
|
||||
|
||||
Either way, the code gets built by driving **`/tdd`** (one red-green slice at a time) and closes out with **`/code-review`**, a two-axis review (Standards + Spec) of the diff. `/implement` runs both per ticket; `/implement-spec`'s implementers each drive `/tdd`, and it runs one `/code-review` over the integration branch. Reach for **`/tdd`** on its own when you just want to build a concrete behaviour test-first without a full spec, and **`/code-review`** on its own whenever you want to review a branch or PR against a fixed point.
|
||||
|
||||
When the work goes up as a pull request, **`/pr`** shapes the body: the smallest visual that shows the change, before/after evidence that it works, and a one-way or two-way door call. It's model-invoked, so the agent reaches for it whenever it writes a PR.
|
||||
|
||||
4. **`/retro`** closes the loop. After a build, and especially one that went sideways, it looks back over the session and suggests changes to the agent's **environment**, not the code: navigation pointers, automated checks, the coding standards `/code-review` enforces, steering files, tooling. Mechanical mistakes become deterministic checks; judgement calls become coding standards. The next build then starts from a better environment.
|
||||
|
||||
### Context hygiene
|
||||
|
||||
Keep steps 1–3 in **one unbroken context window** (don't compact or clear until after `/to-tickets`) so the grilling, spec, and tickets all build on the same thinking. Each `/implement` then starts fresh, working from the ticket. Run `/retro` in the session it's looking back on, before you clear; after clearing, point it at that session's log instead.
|
||||
|
||||
The limit on this is the **[smart zone](https://www.aihero.dev/ai-coding-dictionary/smart-zone)**: the window (~150k tokens on state-of-the-art models) within which the model still reasons sharply. If a session approaches it before `/to-tickets`, don't push on degraded; `/compact` at the nearest phase boundary and carry on (see Phase boundaries).
|
||||
|
||||
## On-ramps
|
||||
|
||||
A starting situation that generates work, then merges onto the main flow.
|
||||
|
||||
- **Bugs and requests piling up** → **`/triage`**. It moves issues through triage roles and produces agent-ready issues, which **`/implement`** later picks up.
|
||||
|
||||
Triage is only for issues **you didn't create**: bug reports, incoming feature requests, anything that arrives raw. Tickets that `/to-tickets` produced are already agent-ready, so **don't triage them**.
|
||||
|
||||
- **Something's broken** → **`/diagnosing-bugs`**. For the hard ones: the bug that resists a first glance, the intermittent flake, the regression that crept in between two known-good states. It refuses to theorise until it has a **tight feedback loop** (one command that already goes red on *this* bug), then fixes with a regression test. Once the fix is in, run **`/retro`** in the same session to ask what would have prevented the bug; where the real finding is that there's no good seam to lock it down, that's a job for **`/improve-codebase-architecture`**.
|
||||
|
||||
- **A huge, foggy effort: a greenfield project or a huge feature build, too big for one session** → **`/wayfinder`**, the most cognitively demanding flow here. When the way from here to the destination isn't visible yet, it charts a **shared map** of **decision tickets** on the issue tracker and resolves them one at a time, producing **decisions, not deliverables**, until the fog is pushed back and the way is clear. Where **`/grill-with-docs`** sharpens an idea you can hold in one session, wayfinder is for the idea you can't, and it's slower and denser, so save it for exactly that, never a well-scoped feature.
|
||||
|
||||
When the map clears, **it hands off, it doesn't build**: merge onto the main flow at **`/to-spec`**, which collapses the map's linked decisions into a buildable plan, then `/to-tickets` and `/implement` as usual. Looping the map straight into `/implement` skips that collapse and throws the linked detail away, so go straight to `/implement` only when the effort turned out genuinely small.
|
||||
|
||||
## Codebase health
|
||||
|
||||
Not feature work, just upkeep.
|
||||
|
||||
- **`/improve-codebase-architecture`** runs whenever you have a spare moment to keep the codebase good for agents to operate in. It surfaces **deepening opportunities**; picking one _generates an idea_ you can take into the main flow at `/grill-with-docs`. It's the survey that finds the candidates; **`/codebase-design`** (below) is the bench you design the chosen one on.
|
||||
|
||||
## Vocabulary underneath
|
||||
|
||||
Two model-invoked references that run *beneath* the other skills, each the single source of truth for its vocabulary. Reach for them directly when the **words**, not the process, are the problem; or let the skills above pull them in.
|
||||
|
||||
- **`/domain-modeling`**: sharpen the project's *domain* language: challenge a fuzzy term, resolve an overloaded word ("account" doing three jobs), record a hard-to-reverse decision as an ADR. It's the active discipline `/grill-with-docs` drives to keep `GLOSSARY.md` a clean glossary.
|
||||
- **`/codebase-design`** is the deep-module vocabulary (module, interface, depth, seam, adapter, leverage, locality) for designing a module's *shape*: a lot of behaviour behind a small interface at a clean seam. `/tdd` and `/improve-codebase-architecture` both speak it.
|
||||
|
||||
## Phase boundaries
|
||||
|
||||
A **phase** is a chunk of work inside a session: the grilling, the implementation, the QA. At the **boundary** between two of them you have five options, and picking between them is the fuzziest decision in this whole map:
|
||||
|
||||
- **Continue**: stay put. Costs nothing, loses nothing.
|
||||
- **`/clear`**: empty the window, when nothing here matters to what's next.
|
||||
- **`/handoff`** writes a portable markdown file. Narrow: only for a **new harness**, a **new directory**, a **colleague**, or forking a side task **mid-phase**. What it buys is portability.
|
||||
- **Subagent**: send a tightly-scoped task to its own window and get a report back.
|
||||
- **`/compact`** compresses this context and seeds a fresh session with it. The **default**, at the bottom of the tree rather than the first reach.
|
||||
|
||||
Read [PHASE-BOUNDARIES.md](PHASE-BOUNDARIES.md) for the ordered tree: the five questions, the reasoning behind each branch, and why the primary-source cost makes **Continue** the one to rule out first. Make the decision **at** a boundary; mid-phase, continue or split the rest into subagents.
|
||||
|
||||
## Standalone
|
||||
|
||||
Off the main flow entirely.
|
||||
|
||||
- **`/grill-me`**: the same relentless interview as `/grill-with-docs`, but **stateless**: it saves nothing locally and builds no `GLOSSARY.md`. Reach for it when you are **not working in a working directory** (sharpening a plan, a design, a piece of writing, anything with no repo under it). If you are in a working directory, use `/grill-with-docs` instead: it runs the same interview and leaves a paper trail, so it is strictly the better one.
|
||||
- **`/grilling`** is the interview primitive itself: rounds, the frontier, facts are the agent's job and decisions are yours. `/grill-me` and `/grill-with-docs` are the two named ways in, and `/triage`, `/wayfinder` and `/improve-codebase-architecture` all run it internally. Reach for it directly only when you want the interview with no wrapper around it.
|
||||
- **`/prototype`** is a small, throwaway program that answers one design question: does this state model feel right, or what should this UI look like. Throwaway is a constraint on how the code is written, not a promise to destroy it: the answer folds into the real code, and the prototype itself is kept as a **primary source** on a `prototype/<name>` branch out of main, pointed at from the implementation issue. It's the detour in step 2 of the main flow, but reach for it any time a design question is hard to settle on paper.
|
||||
- **`/research`**: delegate reading legwork to a **background agent**: it investigates a question against **primary sources**, then leaves a cited Markdown file in the repo. Keep working while it reads. The file it produces is something to take *into* the main flow at `/grill-with-docs`, since research feeds the thinking rather than replacing it.
|
||||
- **`/to-questionnaire`** comes in when the thing blocking you isn't in your head or the codebase but in **someone else's**, and it writes them a questionnaire to fill in. It's the inverse of `/grill-me`: instead of interviewing you about the subject, it interviews you about the **send** (who it's going to, what you need back) and aims the questions at the gap. What comes back is material for `/grill-with-docs` or `/to-spec`.
|
||||
- **`/wizard`** is for the steps only a **human** can take: provisioning infrastructure, setting up credentials or CI secrets, clicking through an unfamiliar third-party dashboard, running a one-off migration or cutover. It generates an interactive bash script that opens each URL, captures each value, and writes it into `.env` and GitHub secrets, so the procedure stops being something you re-explain to an agent every time. Model-invoked, so the agent reaches for it the moment it hits a wall only you can pass. If the agent could just do it itself, it should; this is for where a human is genuinely in the loop.
|
||||
- **`/wait-what`** is the corrective for a message that didn't land. Use it mid-conversation, inside any other skill, and the agent re-pitches what it just said with the context you were missing, in plain English, using the `GLOSSARY.md` vocabulary. It works after the fact; `/grill-with-docs` is the upfront cure, because a shared language agreed early is what stops the jargon arriving at all.
|
||||
- **`/teach`**: learn a concept over multiple sessions, using the current directory as a stateful workspace.
|
||||
- **`/writing-for-agents`** is the reference for writing documents agents consume: skills, AGENTS.md, pointed-at docs.
|
||||
|
||||
## Precondition
|
||||
|
||||
**`/setup-matt-pocock-skills`**: run before your first engineering flow to configure the issue tracker, triage labels, and doc layout the other skills assume. Custom issue trackers also work.

# Brainstorming Ideas Into Designs
|
||||
|
||||
Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
|
||||
|
||||
Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
|
||||
|
||||
<HARD-GATE>
|
||||
Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
|
||||
</HARD-GATE>
|
||||
|
||||
## Anti-Pattern: "This Is Too Simple To Need A Design"
|
||||
|
||||
Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
|
||||
|
||||
## Checklist
|
||||
|
||||
You MUST create a task for each of these items and complete them in order:
|
||||
|
||||
1. **Explore project context** — check files, docs, recent commits
|
||||
2. **Offer visual companion** (if topic will involve visual questions) — this is its own message, not combined with a clarifying question. See the Visual Companion section below.
|
||||
3. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
|
||||
4. **Propose 2-3 approaches** — with trade-offs and your recommendation
|
||||
5. **Present design** — in sections scaled to their complexity, get user approval after each section
|
||||
6. **Write design doc** — save to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` and commit
|
||||
7. **Spec self-review** — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
|
||||
8. **User reviews written spec** — ask user to review the spec file before proceeding
|
||||
9. **Transition to implementation** — invoke writing-plans skill to create implementation plan
|
||||
|
||||

}
|
||||
```
|
||||
|
||||
**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
|
||||
|
||||
## The Process
|
||||
|
||||
**Understanding the idea:**
|
||||
|
||||
- Check out the current project state first (files, docs, recent commits)
|
||||
- Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., "build a platform with chat, file storage, billing, and analytics"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.
|
||||
- If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.
|
||||
- For appropriately-scoped projects, ask questions one at a time to refine the idea
|
||||
- Prefer multiple choice questions when possible, but open-ended is fine too
|
||||
- Only one question per message - if a topic needs more exploration, break it into multiple questions
|
||||
- Focus on understanding: purpose, constraints, success criteria
|
||||
|
||||
**Exploring approaches:**
|
||||
|
||||
- Propose 2-3 different approaches with trade-offs
|
||||
- Present options conversationally with your recommendation and reasoning
|
||||
- Lead with your recommended option and explain why
|
||||
|
||||
**Presenting the design:**
|
||||
|
||||
- Once you believe you understand what you're building, present the design
|
||||
- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
|
||||
- Ask after each section whether it looks right so far
|
||||
- Cover: architecture, components, data flow, error handling, testing
|
||||
- Be ready to go back and clarify if something doesn't make sense
|
||||
|
||||
**Design for isolation and clarity:**
|
||||
|
||||
- Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently
|
||||
- For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?
|
||||
- Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.
|
||||
- Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.
|
||||
|
||||
**Working in existing codebases:**
|
||||
|
||||
- Explore the current structure before proposing changes. Follow existing patterns.
|
||||
- Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.
|
||||
- Don't propose unrelated refactoring. Stay focused on what serves the current goal.
|
||||
|
||||
## After the Design
|
||||
|
||||
**Documentation:**
|
||||
|
||||
- Write the validated design (spec) to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md`
|
||||
- (User preferences for spec location override this default)
|
||||
- Use elements-of-style:writing-clearly-and-concisely skill if available
|
||||
- Commit the design document to git
|
||||
|
||||
**Spec Self-Review:**
|
||||
After writing the spec document, look at it with fresh eyes:
|
||||
|
||||
1. **Placeholder scan:** Any "TBD", "TODO", incomplete sections, or vague requirements? Fix them.
|
||||
2. **Internal consistency:** Do any sections contradict each other? Does the architecture match the feature descriptions?
|
||||
3. **Scope check:** Is this focused enough for a single implementation plan, or does it need decomposition?
|
||||
4. **Ambiguity check:** Could any requirement be interpreted two different ways? If so, pick one and make it explicit.
|
||||
|
||||
Fix any issues inline. No need to re-review — just fix and move on.
|
||||
|
||||
**User Review Gate:**
|
||||
After the spec review loop passes, ask the user to review the written spec before proceeding:
|
||||
|
||||
> "Spec written and committed to `<path>`. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
|
||||
|
||||
Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.
|
||||
|
||||
**Implementation:**
|
||||
|
||||
- Invoke the writing-plans skill to create a detailed implementation plan
|
||||
- Do NOT invoke any other skill. writing-plans is the next step.
|
||||
|
||||
## Key Principles
|
||||
|
||||
- **One question at a time** - Don't overwhelm with multiple questions
|
||||
- **Multiple choice preferred** - Easier to answer than open-ended when possible
|
||||
- **YAGNI ruthlessly** - Remove unnecessary features from all designs
|
||||
- **Explore alternatives** - Always propose 2-3 approaches before settling
|
||||
- **Incremental validation** - Present design, get approval before moving on
|
||||
- **Be flexible** - Go back and clarify when something doesn't make sense
|
||||
|
||||
## Visual Companion
|
||||
|
||||
A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.
|
||||
|
||||
**Offering the companion:** When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent:
|
||||
> "Some of what we're working on might be easier to explain if I can show it to you in a web browser. I can put together mockups, diagrams, comparisons, and other visuals as we go. This feature is still new and can be token-intensive. Want to try it? (Requires opening a local URL)"
|
||||
|
||||
**This offer MUST be its own message.** Do not combine it with clarifying questions, context summaries, or any other content. The message should contain ONLY the offer above and nothing else. Wait for the user's response before continuing. If they decline, proceed with text-only brainstorming.
|
||||
|
||||
**Per-question decision:** Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: **would the user understand this better by seeing it than reading it?**
|
||||
|
||||
- **Use the browser** for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs
|
||||
- **Use the terminal** for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions
|
||||
|
||||
A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.
|
||||
|
||||
If they agree to the companion, read the detailed guide before proceeding:

# Visual Companion Guide
|
||||
|
||||
Browser-based visual brainstorming companion for showing mockups, diagrams, and options.
|
||||
|
||||
## When to Use
|
||||
|
||||
Decide per-question, not per-session. The test: **would the user understand this better by seeing it than reading it?**
|
||||
|
||||
**Use the browser** when the content itself is visual:
|
||||
|
||||
- **UI mockups** — wireframes, layouts, navigation structures, component designs
|
||||
- **Architecture diagrams** — system components, data flow, relationship maps
|
||||
- **Side-by-side visual comparisons** — comparing two layouts, two color schemes, two design directions
|
||||
- **Design polish** — when the question is about look and feel, spacing, visual hierarchy
|
||||
- **Spatial relationships** — state machines, flowcharts, entity relationships rendered as diagrams
|
||||
|
||||
**Use the terminal** when the content is text or tabular:
|
||||
|
||||
- **Requirements and scope questions** — "what does X mean?", "which features are in scope?"
|
||||
- **Conceptual A/B/C choices** — picking between approaches described in words
|
||||
- **Tradeoff lists** — pros/cons, comparison tables
|
||||
- **Technical decisions** — API design, data modeling, architectural approach selection
|
||||
- **Clarifying questions** — anything where the answer is words, not a visual preference
|
||||
|
||||
A question *about* a UI topic is not automatically a visual question. "What kind of wizard do you want?" is conceptual — use the terminal. "Which of these wizard layouts feels right?" is visual — use the browser.
|
||||
|
||||
## How It Works
|
||||
|
||||
The server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to `screen_dir`, the user sees it in their browser and can click to select options. Selections are recorded to `state_dir/events` that you read on your next turn.
|
||||
|
||||
**Content fragments vs full documents:** If your HTML file starts with `<!DOCTYPE` or `<html`, the server serves it as-is (just injects the helper script). Otherwise, the server automatically wraps your content in the frame template — adding the header, CSS theme, selection indicator, and all interactive infrastructure. **Write content fragments by default.** Only write full documents when you need complete control over the page.
|
||||
|
||||
## Starting a Session
|
||||
|
||||
```bash
|
||||
# Start server with persistence (mockups saved to project)
|
||||
scripts/start-server.sh --project-dir /path/to/project
|
||||
|
||||
# Returns: {"type":"server-started","port":52341,"url":"http://localhost:52341",
|
||||
# "screen_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/content",
|
||||
# "state_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/state"}
|
||||
```
|
||||
|
||||
Save `screen_dir` and `state_dir` from the response. Tell user to open the URL.
|
||||
|
||||
**Finding connection info:** The server writes its startup JSON to `$STATE_DIR/server-info`. If you launched the server in the background and didn't capture stdout, read that file to get the URL and port. When using `--project-dir`, check `<project>/.superpowers/brainstorm/` for the session directory.
|
||||
|
||||
**Note:** Pass the project root as `--project-dir` so mockups persist in `.superpowers/brainstorm/` and survive server restarts. Without it, files go to `/tmp` and get cleaned up. Remind the user to add `.superpowers/` to `.gitignore` if it's not already there.
|
||||
|
||||
**Launching the server by platform:**
|
||||
|
||||
**Claude Code (macOS / Linux):**
|
||||
```bash
|
||||
# Default mode works — the script backgrounds the server itself
|
||||
scripts/start-server.sh --project-dir /path/to/project
|
||||
```
|
||||
|
||||
**Claude Code (Windows):**
|
||||
```bash
|
||||
# Windows auto-detects and uses foreground mode, which blocks the tool call.
|
||||
# Use run_in_background: true on the Bash tool call so the server survives
|
||||
# across conversation turns.
|
||||
scripts/start-server.sh --project-dir /path/to/project
|
||||
```
|
||||
When calling this via the Bash tool, set `run_in_background: true`. Then read `$STATE_DIR/server-info` on the next turn to get the URL and port.
|
||||
|
||||
**Codex:**
|
||||
```bash
|
||||
# Codex reaps background processes. The script auto-detects CODEX_CI and
|
||||
# switches to foreground mode. Run it normally — no extra flags needed.
|
||||
scripts/start-server.sh --project-dir /path/to/project
|
||||
```
|
||||
|
||||
**Gemini CLI:**
|
||||
```bash
|
||||
# Use --foreground and set is_background: true on your shell tool call
|
||||
# so the process survives across turns
|
||||
scripts/start-server.sh --project-dir /path/to/project --foreground
|
||||
```
|
||||
|
||||
**Other environments:** The server must keep running in the background across conversation turns. If your environment reaps detached processes, use `--foreground` and launch the command with your platform's background execution mechanism.
|
||||
|
||||
If the URL is unreachable from your browser (common in remote/containerized setups), bind a non-loopback host:
|
||||
|
||||
```bash
|
||||
scripts/start-server.sh \
|
||||
--project-dir /path/to/project \
|
||||
--host 0.0.0.0 \
|
||||
--url-host localhost
|
||||
```
|
||||
|
||||
Use `--url-host` to control what hostname is printed in the returned URL JSON.
|
||||
|
||||
## The Loop
|
||||
|
||||
1. **Check server is alive**, then **write HTML** to a new file in `screen_dir`:
|
||||
- Before each write, check that `$STATE_DIR/server-info` exists. If it doesn't (or `$STATE_DIR/server-stopped` exists), the server has shut down — restart it with `start-server.sh` before continuing. The server auto-exits after 30 minutes of inactivity.
|
||||
- Use semantic filenames: `platform.html`, `visual-style.html`, `layout.html`
|
||||
- **Never reuse filenames** — each screen gets a fresh file
|
||||
- Use Write tool — **never use cat/heredoc** (dumps noise into terminal)
|
||||
- Server automatically serves the newest file
|
||||
|
||||
2. **Tell user what to expect and end your turn:**
|
||||
- Remind them of the URL (every step, not just first)
|
||||
- Give a brief text summary of what's on screen (e.g., "Showing 3 layout options for the homepage")
|
||||
- Ask them to respond in the terminal: "Take a look and let me know what you think. Click to select an option if you'd like."
|
||||
|
||||
3. **On your next turn** — after the user responds in the terminal:
|
||||
- Read `$STATE_DIR/events` if it exists — this contains the user's browser interactions (clicks, selections) as JSON lines
|
||||
- Merge with the user's terminal text to get the full picture
|
||||
- The terminal message is the primary feedback; `state_dir/events` provides structured interaction data
|
||||
|
||||
4. **Iterate or advance** — if feedback changes current screen, write a new file (e.g., `layout-v2.html`). Only move to the next question when the current step is validated.
|
||||
|
||||
5. **Unload when returning to terminal** — when the next step doesn't need the browser (e.g., a clarifying question, a tradeoff discussion), push a waiting screen to clear the stale content:
|
||||
|
||||
```html
|
||||
<!-- filename: waiting.html (or waiting-2.html, etc.) -->
|
||||
<div style="display:flex;align-items:center;justify-content:center;min-height:60vh">
|
||||
<p class="subtitle">Continuing in terminal...</p>
|
||||
</div>
|
||||
```
|
||||
|
||||
This prevents the user from staring at a resolved choice while the conversation has moved on. When the next visual question comes up, push a new content file as usual.
|
||||
|
||||
6. Repeat until done.
|
||||
|
||||
## Writing Content Fragments
|
||||
|
||||
Write just the content that goes inside the page. The server wraps it in the frame template automatically (header, theme CSS, selection indicator, and all interactive infrastructure).
|
||||
|
||||
**Minimal example:**
|
||||
|
||||
```html
|
||||
<h2>Which layout works better?</h2>
|
||||
<p class="subtitle">Consider readability and visual hierarchy</p>
|
||||
|
||||
<div class="options">
|
||||
<div class="option" data-choice="a" onclick="toggleSelect(this)">
|
||||
<div class="letter">A</div>
|
||||
<div class="content">
|
||||
<h3>Single Column</h3>
|
||||
<p>Clean, focused reading experience</p>
|
||||
</div>
|
||||
</div>
|
||||
<div class="option" data-choice="b" onclick="toggleSelect(this)">
|
||||
<div class="letter">B</div>
|
||||
<div class="content">
|
||||
<h3>Two Column</h3>
|
||||
<p>Sidebar navigation with main content</p>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
That's it. No `<html>`, no CSS, no `<script>` tags needed. The server provides all of that.
|
||||
|
||||
## CSS Classes Available
|
||||
|
||||
The frame template provides these CSS classes for your content:
|
||||
|
||||
### Options (A/B/C choices)
|
||||
|
||||
```html
|
||||
<div class="options">
|
||||
<div class="option" data-choice="a" onclick="toggleSelect(this)">
|
||||
<div class="letter">A</div>
|
||||
<div class="content">
|
||||
<h3>Title</h3>
|
||||
<p>Description</p>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
**Multi-select:** Add `data-multiselect` to the container to let users select multiple options. Each click toggles the item. The indicator bar shows the count.
|
||||
|
||||
```html
|
||||
<div class="options" data-multiselect>
|
||||
<!-- same option markup — users can select/deselect multiple -->
|
||||
</div>
|
||||
```
|
||||
|
||||
### Cards (visual designs)
|
||||
|
||||
```html
|
||||
<div class="cards">
|
||||
<div class="card" data-choice="design1" onclick="toggleSelect(this)">
|
||||
<div class="card-image"><!-- mockup content --></div>
|
||||
<div class="card-body">
|
||||
<h3>Name</h3>
|
||||
<p>Description</p>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Mockup container
|
||||
|
||||
```html
|
||||
<div class="mockup">
|
||||
<div class="mockup-header">Preview: Dashboard Layout</div>
|
||||
<div class="mockup-body"><!-- your mockup HTML --></div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Split view (side-by-side)
|
||||
|
||||
```html
|
||||
<div class="split">
|
||||
<div class="mockup"><!-- left --></div>
|
||||
<div class="mockup"><!-- right --></div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Pros/Cons
|
||||
|
||||
```html
|
||||
<div class="pros-cons">
|
||||
<div class="pros"><h4>Pros</h4><ul><li>Benefit</li></ul></div>
|
||||
<div class="cons"><h4>Cons</h4><ul><li>Drawback</li></ul></div>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Mock elements (wireframe building blocks)
|
||||
|
||||
```html
|
||||
<div class="mock-nav">Logo | Home | About | Contact</div>
|
||||
<div style="display: flex;">
|
||||
<div class="mock-sidebar">Navigation</div>
|
||||
<div class="mock-content">Main content area</div>
|
||||
</div>
|
||||
<button class="mock-button">Action Button</button>
|
||||
<input class="mock-input" placeholder="Input field">
|
||||
<div class="placeholder">Placeholder area</div>
|
||||
```
|
||||
|
||||
### Typography and sections
|
||||
|
||||
- `h2` — page title
|
||||
- `h3` — section heading
|
||||
- `.subtitle` — secondary text below title
|
||||
- `.section` — content block with bottom margin
|
||||
- `.label` — small uppercase label text
|
||||
|
||||
## Browser Events Format
|
||||
|
||||
When the user clicks options in the browser, their interactions are recorded to `$STATE_DIR/events` (one JSON object per line). The file is cleared automatically when you push a new screen.
|
||||
|
||||
```jsonl
|
||||
{"type":"click","choice":"a","text":"Option A - Simple Layout","timestamp":1706000101}
|
||||
{"type":"click","choice":"c","text":"Option C - Complex Grid","timestamp":1706000108}
|
||||
{"type":"click","choice":"b","text":"Option B - Hybrid","timestamp":1706000115}
|
||||
```
|
||||
|
||||
The full event stream shows the user's exploration path — they may click multiple options before settling. The last `choice` event is typically the final selection, but the pattern of clicks can reveal hesitation or preferences worth asking about.
|
||||
|
||||
If `$STATE_DIR/events` doesn't exist, the user didn't interact with the browser — use only their terminal text.
|
||||
|
||||
## Design Tips
|
||||
|
||||
- **Scale fidelity to the question** — wireframes for layout, polish for polish questions
|
||||
- **Explain the question on each page** — "Which layout feels more professional?" not just "Pick one"
|
||||
- **Iterate before advancing** — if feedback changes current screen, write a new version
|
||||
- **2-4 options max** per screen
|
||||
- **Use real content when it matters** — for a photography portfolio, use actual images (Unsplash). Placeholder content obscures design issues.
|
||||
- **Keep mockups simple** — focus on layout and structure, not pixel-perfect design
|
||||
|
||||
## File Naming
|
||||
|
||||
- Use semantic names: `platform.html`, `visual-style.html`, `layout.html`
|
||||
- Never reuse filenames — each screen must be a new file
|
||||
- For iterations: append version suffix like `layout-v2.html`, `layout-v3.html`
|
||||
- Server serves newest file by modification time
|
||||
|
||||
## Cleaning Up
|
||||
|
||||
```bash
|
||||
scripts/stop-server.sh $SESSION_DIR
|
||||
```
|
||||
|
||||
If the session used `--project-dir`, mockup files persist in `.superpowers/brainstorm/` for later reference. Only `/tmp` sessions get deleted on stop.
|
||||

||||

description: "Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\"."
|
||||
---
|
||||
|
||||
Two-axis review of the diff between `HEAD` and a fixed point the user supplies:
|
||||
|
||||
- **Standards**: does the code conform to this repo's documented coding standards?
|
||||
- **Spec**: does the code faithfully implement the originating issue / spec?
|
||||
|
||||
Both axes run as **parallel sub-agents** so they don't pollute each other's context, then this skill aggregates their findings. Start every sub-agent with a fresh context window.
|
||||
|
||||
The issue tracker should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. Pin the fixed point
|
||||
|
||||
Whatever the user said is the fixed point (a commit SHA, branch name, tag, `main`, `HEAD~5`, etc.). If they didn't specify one, ask for it.
|
||||
|
||||
Capture the diff command once: `git diff <fixed-point>...HEAD` (three-dot, so the comparison is against the merge-base). Also note the list of commits via `git log <fixed-point>..HEAD --oneline`.
|
||||
|
||||
Before going further, confirm the fixed point resolves (`git rev-parse <fixed-point>`) and the diff is non-empty. A bad ref or empty diff should fail here, not inside two parallel sub-agents.
|
||||
|
||||
### 2. Identify the spec source
|
||||
|
||||
Look for the originating spec, in this order:
|
||||
|
||||
1. Issue references in the commit messages (`#123`, `Closes #45`, GitLab `!67`, etc.), fetched via the workflow in the tracker doc.
|
||||
2. A path the user passed as an argument.
|
||||
3. A spec file under `docs/`, `specs/`, or `.scratch/` matching the branch name or feature.
|
||||
4. If nothing is found, ask the user where the spec is. If they say there isn't one, the **Spec** sub-agent will skip and report "no spec available".
|
||||
|
||||
### 3. Identify the standards sources
|
||||
|
||||
Search the repo for every file that documents how code should be written. When `CODING_STANDARDS.md` or `CONTRIBUTING.md` exists, it must be on the list.
|
||||
|
||||
On top of whatever the repo documents, the Standards axis always carries the **smell baseline** below: a fixed set of Fowler code smells (_Refactoring_, ch.3) that applies even when a repo documents nothing. Two rules bind it:
|
||||
|
||||
- **The repo overrides.** A documented repo standard always wins; where it endorses something the baseline would flag, suppress the smell.
|
||||
- **Always a judgement call.** Each smell is a labelled heuristic ("possible Feature Envy"), never a hard violation. Like any standard here, skip anything tooling already enforces.
|
||||
|
||||
Each smell reads *what it is* → *how to fix*; match it against the diff:
|
||||
|
||||
- **Mysterious Name**: a function, variable, or type whose name doesn't reveal what it does or holds. → rename it; if no honest name comes, the design's murky.
|
||||
- **Duplicated Code**: the same logic shape appears in more than one hunk or file in the change. → extract the shared shape, call it from both.
|
||||
- **Feature Envy**: a method that reaches into another object's data more than its own. → move the method onto the data it envies.
|
||||
- **Data Clumps**: the same few fields or params keep travelling together (a type wanting to be born). → bundle them into one type, pass that.
|
||||
- **Primitive Obsession**: a primitive or string standing in for a domain concept that deserves its own type. → give the concept its own small type.
|
||||
- **Repeated Switches**: the same `switch`/`if`-cascade on the same type recurs across the change. → replace with polymorphism, or one map both sites share.
|
||||
- **Shotgun Surgery**: one logical change forces scattered edits across many files in the diff. → gather what changes together into one module.
|
||||
- **Divergent Change**: one file or module is edited for several unrelated reasons. → split so each module changes for one reason.
|
||||
- **Speculative Generality**: abstraction, parameters, or hooks added for needs the spec doesn't have. → delete it; inline back until a real need shows.
|
||||
- **Message Chains**: long `a.b().c().d()` navigation the caller shouldn't depend on. → hide the walk behind one method on the first object.
|
||||
- **Middle Man**: a class or function that mostly just delegates onward. → cut it, call the real target direct.
|
||||
- **Refused Bequest**: a subclass or implementer that ignores or overrides most of what it inherits. → drop the inheritance, use composition.
|
||||
|
||||
### 4. Spawn both sub-agents in parallel
|
||||
|
||||
Issue both sub-agent calls together, in the foreground, and aggregate the reports they return.
|
||||
|
||||
**Standards sub-agent prompt** should include:
|
||||
|
||||
- The full diff command and commit list.
|
||||
- The list of standards-source files you found in step 3, **plus the smell baseline from step 3** pasted in full (the sub-agent has no other access to it).
|
||||
- The brief: "Report, per file/hunk where relevant, (a) every place the diff violates a documented standard: cite the standard (file + the rule); and (b) any baseline smell you spot: name it and quote the hunk. Distinguish hard violations from judgement calls: documented-standard breaches can be hard, but baseline smells are always judgement calls, and a documented repo standard overrides the baseline. Skip anything tooling enforces. Under 400 words."
|
||||
|
||||
**Spec sub-agent prompt** should include:
|
||||
|
||||
- The diff command and commit list.
|
||||
- The path or fetched contents of the spec.
|
||||
- The brief: "Report: (a) requirements the spec asked for that are missing or partial; (b) behaviour in the diff that wasn't asked for (scope creep); (c) requirements that look implemented but where the implementation looks wrong. Quote the spec line for each finding. Under 400 words."
|
||||
|
||||
If the spec is missing, skip the Spec sub-agent and note this in the final report.
|
||||
|
||||
### 5. Aggregate
|
||||
|
||||
Present the two reports under `## Standards` and `## Spec` headings, verbatim or lightly cleaned. Do **not** merge or rerank findings, because the two axes are deliberately separate (see _Why two axes_).
|
||||
|
||||
End with a one-line summary: total findings per axis, and the worst issue _within each axis_ (if any). Don't pick a single winner across axes: that's the reranking the separation exists to prevent.
|
||||
|
||||
## Why two axes
|
||||
|
||||
A change can pass one axis and fail the other:
|
||||
|
||||
- Code that follows every standard but implements the wrong thing → **Standards pass, Spec fail.**
|
||||
- Code that does exactly what the issue asked but breaks the project's conventions → **Spec pass, Standards fail.**
|
||||
|
||||
Reporting them separately stops one axis from masking the other.

# Deepening
|
||||
|
||||
How to deepen a cluster of shallow modules safely, given its dependencies. Assumes the vocabulary in [SKILL.md](SKILL.md): **module**, **interface**, **seam**, **adapter**.
|
||||
|
||||
## Dependency categories
|
||||
|
||||
When assessing a candidate for deepening, classify its dependencies. The category determines how the deepened module is tested across its seam.
|
||||
|
||||
### 1. In-process
|
||||
|
||||
Pure computation, in-memory state, no I/O. Always deepenable: merge the modules and test through the new interface directly. No adapter needed.
|
||||
|
||||
### 2. Local-substitutable
|
||||
|
||||
Dependencies that have local test stand-ins (PGLite for Postgres, in-memory filesystem). Deepenable if the stand-in exists. The deepened module is tested with the stand-in running in the test suite. The seam is internal; no port at the module's external interface.
|
||||
|
||||
### 3. Remote but owned (Ports & Adapters)
|
||||
|
||||
Your own services across a network boundary (microservices, internal APIs). Define a **port** (interface) at the seam. The deep module owns the logic; the transport is injected as an **adapter**. Tests use an in-memory adapter. Production uses an HTTP/gRPC/queue adapter.
|
||||
|
||||
Recommendation shape: *"Define a port at the seam, implement an HTTP adapter for production and an in-memory adapter for testing, so the logic sits in one deep module even though it's deployed across a network."*
|
||||
|
||||
### 4. True external (Mock)
|
||||
|
||||
Third-party services (Stripe, Twilio, etc.) you don't control. The deepened module takes the external dependency as an injected port; tests provide a mock adapter.
|
||||
|
||||
## Seam discipline
|
||||
|
||||
- **One adapter means a hypothetical seam. Two adapters means a real one.** Don't introduce a port unless at least two adapters are justified (typically production + test). A single-adapter seam is just indirection.
|
||||
- **Internal seams vs external seams.** A deep module can have internal seams (private to its implementation, used by its own tests) as well as the external seam at its interface. Don't expose internal seams through the interface just because tests use them.
|
||||
|
||||
## Testing strategy: replace, don't layer
|
||||
|
||||
- Old unit tests on shallow modules become waste once tests at the deepened module's interface exist; delete them.
|
||||
- Write new tests at the deepened module's interface. The **interface is the test surface**.
|
||||
- Tests assert on observable outcomes through the interface, not internal state.
|
||||
- Tests should survive internal refactors, since they describe behaviour, not implementation. If a test has to change when the implementation changes, it's testing past the interface.

# Design It Twice
|
||||
|
||||
When the user wants to explore alternative interfaces for a chosen deepening candidate, use this parallel sub-agent pattern. Based on "Design It Twice" (Ousterhout): your first idea is unlikely to be the best.
|
||||
|
||||
Uses the vocabulary in [SKILL.md](SKILL.md): **module**, **interface**, **seam**, **adapter**, **leverage**.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. Frame the problem space
|
||||
|
||||
Before spawning sub-agents, write a user-facing explanation of the problem space for the chosen candidate:
|
||||
|
||||
- The constraints any new interface would need to satisfy
|
||||
- The dependencies it would rely on, and which category they fall into (see [DEEPENING.md](DEEPENING.md))
|
||||
- A rough illustrative code sketch to ground the constraints, not a proposal, just a way to make the constraints concrete
|
||||
|
||||
Show this to the user, then immediately proceed to Step 2. The user reads and thinks while the sub-agents work in parallel.
|
||||
|
||||
### 2. Spawn sub-agents
|
||||
|
||||
Spawn 3+ sub-agents in parallel, each with a fresh context window. Each must produce a **radically different** interface for the deepened module.
|
||||
|
||||
Prompt each sub-agent with a separate technical brief (file paths, coupling details, dependency category from [DEEPENING.md](DEEPENING.md), what sits behind the seam). The brief is independent of the user-facing problem-space explanation in Step 1. Give each agent a different design constraint:
|
||||
|
||||
- Agent 1: "Minimize the interface: aim for 1–3 entry points max. Maximise leverage per entry point."
|
||||
- Agent 2: "Maximise flexibility: support many use cases and extension."
|
||||
- Agent 3: "Optimise for the most common caller: make the default case trivial."
|
||||
- Agent 4 (if applicable): "Design around ports & adapters for cross-seam dependencies."
|
||||
|
||||
Include both [SKILL.md](SKILL.md) vocabulary and GLOSSARY.md vocabulary in the brief so each sub-agent names things consistently with the architecture language and the project's domain language.
|
||||
|
||||
Each sub-agent outputs:
|
||||
|
||||
1. Interface (types, methods, params, plus invariants, ordering, error modes)
|
||||
2. Usage example showing how callers use it
|
||||
3. What the implementation hides behind the seam
|
||||
4. Dependency strategy and adapters (see [DEEPENING.md](DEEPENING.md))
|
||||
5. Trade-offs: where leverage is high, where it's thin
|
||||
|
||||
### 3. Present and compare
|
||||
|
||||
Present designs sequentially so the user can absorb each one, then compare them in prose. Contrast by **depth** (leverage at the interface), **locality** (where change concentrates), and **seam placement**.
|
||||
|
||||
After comparing, give your own recommendation: which design you think is strongest and why. If elements from different designs would combine well, propose a hybrid. Be opinionated: the user wants a strong read, not a menu.

# Codebase Design
|
||||
|
||||
Design **deep modules**: a lot of behaviour behind a small interface, placed at a clean seam, testable through that interface. Use this language and these principles wherever code is being designed or restructured. The aim is leverage for callers, locality for maintainers, and testability for everyone.
|
||||
|
||||
## Glossary
|
||||
|
||||
Use these terms exactly: don't substitute "component," "service," "API," or "boundary." Consistent language is the whole point.
|
||||
|
||||
**Module**: anything with an interface and an implementation. Deliberately scale-agnostic: a function, class, package, or tier-spanning slice. _Avoid_: unit, component, service.
|
||||
|
||||
**Interface**: everything a caller must know to use the module correctly: the type signature, but also invariants, ordering constraints, error modes, required configuration, and performance characteristics. _Avoid_: API, signature (too narrow, they refer only to the type-level surface).
|
||||
|
||||
**Implementation**: what's inside a module, its body of code. Distinct from **Adapter**: a thing can be a small adapter with a large implementation (a Postgres repo) or a large adapter with a small implementation (an in-memory fake). Reach for "adapter" when the seam is the topic; "implementation" otherwise.
|
||||
|
||||
**Depth**: leverage at the interface. The amount of behaviour a caller (or test) can exercise per unit of interface they have to learn. A module is **deep** when a large amount of behaviour sits behind a small interface, **shallow** when the interface is nearly as complex as the implementation.
|
||||
|
||||
**Seam** _(Michael Feathers)_: a place where you can alter behaviour without editing in that place; the *location* at which a module's interface lives. Where to put the seam is its own design decision, distinct from what goes behind it. _Avoid_: boundary (overloaded with DDD's bounded context).
|
||||
|
||||
**Adapter**: a concrete thing that satisfies an interface at a seam. Describes *role* (what slot it fills), not substance (what's inside).
|
||||
|
||||
**Leverage**: what callers get from depth. More capability per unit of interface they learn. One implementation pays back across N call sites and M tests.
|
||||
|
||||
**Locality**: what maintainers get from depth. Change, bugs, knowledge, and verification concentrate in one place rather than spreading across callers. Fix once, fixed everywhere.
|
||||
|
||||
## Deep vs shallow
|
||||
|
||||
**Deep module** = small interface + lots of implementation:
|
||||
|
||||
```
|
||||
┌─────────────────────┐
|
||||
│ Small Interface │ ← Few methods, simple params
|
||||
├─────────────────────┤
|
||||
│ │
|
||||
│ Deep Implementation│ ← Complex logic hidden
|
||||
│ │
|
||||
└─────────────────────┘
|
||||
```
|
||||
|
||||
**Shallow module** = large interface + little implementation (avoid):
|
||||
|
||||
```
|
||||
┌─────────────────────────────────┐
|
||||
│ Large Interface │ ← Many methods, complex params
|
||||
├─────────────────────────────────┤
|
||||
│ Thin Implementation │ ← Just passes through
|
||||
└─────────────────────────────────┘
|
||||
```
|
||||
|
||||
When designing an interface, ask:
|
||||
|
||||
- Can I reduce the number of methods?
|
||||
- Can I simplify the parameters?
|
||||
- Can I hide more complexity inside?
|
||||
|
||||
## Principles
|
||||
|
||||
- **Depth is a property of the interface, not the implementation.** A deep module can be internally composed of small, mockable, swappable parts; they just aren't part of the interface. A module can have **internal seams** (private to its implementation, used by its own tests) as well as the **external seam** at its interface.
|
||||
- **The deletion test.** Imagine deleting the module. If complexity vanishes, it was a pass-through. If complexity reappears across N callers, it was earning its keep.
|
||||
- **The interface is the test surface.** Callers and tests cross the same seam. If you want to test *past* the interface, the module is probably the wrong shape.
|
||||
- **One adapter means a hypothetical seam. Two adapters means a real one.** Don't introduce a seam unless something actually varies across it.
|
||||
|
||||
## Designing for testability
|
||||
|
||||
Good interfaces make testing natural:
|
||||
|
||||
1. **Accept dependencies, don't create them.**
|
||||
|
||||
```typescript
|
||||
// Testable
|
||||
function processOrder(order, paymentGateway) {}
|
||||
|
||||
// Hard to test
|
||||
function processOrder(order) {
|
||||
const gateway = new StripeGateway();
|
||||
}
|
||||
```
|
||||
|
||||
2. **Return results, don't produce side effects.**
|
||||
|
||||
```typescript
|
||||
// Testable
|
||||
function calculateDiscount(cart): Discount {}
|
||||
|
||||
// Hard to test
|
||||
function applyDiscount(cart): void {
|
||||
cart.total -= discount;
|
||||
}
|
||||
```
|
||||
|
||||
3. **Small surface area.** Fewer methods = fewer tests needed. Fewer params = simpler test setup.
|
||||
|
||||
## Relationships
|
||||
|
||||
- A **Module** has exactly one **Interface** (the surface it presents to callers and tests).
|
||||
- **Depth** is a property of a **Module**, measured against its **Interface**.
|
||||
- A **Seam** is where a **Module**'s **Interface** lives.
|
||||
- An **Adapter** sits at a **Seam** and satisfies the **Interface**.
|
||||
- **Depth** produces **Leverage** for callers and **Locality** for maintainers.
|
||||
|
||||
## Rejected framings
|
||||
|
||||
- **Depth as ratio of implementation-lines to interface-lines** (Ousterhout): rewards padding the implementation. We use depth-as-leverage instead.
|
||||
- **"Interface" as the TypeScript `interface` keyword or a class's public methods**: too narrow: interface here includes every fact a caller must know.
|
||||
- **"Boundary"**: overloaded with DDD's bounded context. Say **seam** or **interface**.
|
||||
|
||||
## Going deeper
|
||||
|
||||
- **Deepening a cluster given its dependencies**, see [DEEPENING.md](DEEPENING.md): dependency categories, seam discipline, and replace-don't-layer testing.
|
||||
- **Exploring alternative interfaces**, see [DESIGN-IT-TWICE.md](DESIGN-IT-TWICE.md): spin up parallel sub-agents to design the interface several radically different ways, then compare on depth, locality, and seam placement.

# Diagnosing Bugs
|
||||
|
||||
A discipline for hard bugs. Skip phases only when explicitly justified.
|
||||
|
||||
When exploring the codebase, read `GLOSSARY.md` (if it exists) to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.
|
||||
|
||||
## Redact
|
||||
|
||||
This skill has you show commands, outputs and captured artifacts. **Redact every secret first**: write `<REDACTED>` in its place. Build loops against env vars, so the credential stays in the environment rather than in what you show. Captured artifacts carry auth headers: quote only the lines that carry the signal.
|
||||
|
||||
If the redacted output is not enough to diagnose the bug, say so and ask the user.
|
||||
|
||||
## Phase 1: Build a feedback loop
|
||||
|
||||
**This is the skill.** Everything else is mechanical. If you have a **tight** pass/fail signal for the bug (one that goes red on _this_ bug), you will find the cause; bisection, hypothesis-testing, and instrumentation all just consume it. If you don't have one, no amount of staring at code will save you.
|
||||
|
||||
Spend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**
|
||||
|
||||
### Ways to construct one, in roughly this order
|
||||
|
||||
1. **Failing test** at whatever seam reaches the bug: unit, integration, e2e.
|
||||
2. **Curl / HTTP script** against a running dev server.
|
||||
3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.
|
||||
4. **Headless browser script** (Playwright / Puppeteer) that drives the UI and asserts on DOM/console/network.
|
||||
5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.
|
||||
6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.
|
||||
7. **Property / fuzz loop.** If the bug is "sometimes wrong output", run 1000 random inputs and look for the failure mode.
|
||||
8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate "boot at state X, check, repeat" so you can `git bisect run` it.
|
||||
9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.
|
||||
10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.
|
||||
|
||||
Build the right feedback loop, and the bug is 90% fixed.
|
||||
|
||||
### Tighten the loop
|
||||
|
||||
Treat the loop as a product. Once you have _a_ loop, **tighten** it:
|
||||
|
||||
- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)
|
||||
- Can I make the signal sharper? (Assert on the specific symptom, not "didn't crash".)
|
||||
- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)
|
||||
|
||||
A 30-second flaky loop is barely better than no loop; a 2-second deterministic one is tight, a debugging superpower.
|
||||
|
||||
### Non-deterministic bugs
|
||||
|
||||
The goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not, so keep raising the rate until it's debuggable.
|
||||
|
||||
### When you genuinely cannot build a loop
|
||||
|
||||
Stop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a redacted captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.
|
||||
|
||||
### Completion criterion: a tight loop that goes red
|
||||
|
||||
Phase 1 is done when the loop is **tight** and **red-capable**: you can name **one command** (a script path, a test invocation, a curl) that you have **already run at least once** (show the invocation and its output, redacted), and that is:
|
||||
|
||||
- [ ] **Red-capable**: it drives the actual bug code path and asserts the **user's exact symptom**, so it can go red on this bug and green once fixed. Not "runs without erroring"; it must be able to _catch this specific bug_.
|
||||
- [ ] **Deterministic**: same verdict every run (flaky bugs: a pinned, high reproduction rate, per above).
|
||||
- [ ] **Fast**: seconds, not minutes.
|
||||
- [ ] **Agent-runnable**: you can run it unattended; a human in the loop only via `scripts/hitl-loop.template.sh`.
|
||||
|
||||
If you catch yourself reading code to build a theory before this command exists, **stop: jumping straight to a hypothesis is the exact failure this skill prevents.** No red-capable command, no Phase 2.
|
||||
|
||||
## Phase 2: Reproduce + minimise
|
||||
|
||||
Run the loop. Watch it go red as the bug appears.
|
||||
|
||||
Confirm:
|
||||
|
||||
- [ ] The loop produces the failure mode the **user** described, not a different failure that happens to be nearby. Wrong bug = wrong fix.
|
||||
- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).
|
||||
- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.
|
||||
|
||||
### Minimise
|
||||
|
||||
Once it's red, shrink the repro to the **smallest scenario that still goes red**. Cut inputs, callers, config, data, and steps **one at a time**, re-running the loop after each cut, and keep only what's load-bearing for the failure.
|
||||
|
||||
Why bother: a minimal repro shrinks the hypothesis space in Phase 3 (fewer moving parts left to suspect) and becomes the clean regression test in Phase 5.
|
||||
|
||||
Done when **every remaining element is load-bearing**: removing any one of them makes the loop go green.
|
||||
|
||||
Do not proceed until you have reproduced **and** minimised.
|
||||
|
||||
## Phase 3: Hypothesise
|
||||
|
||||
Generate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.
|
||||
|
||||
Each hypothesis must be **falsifiable**: state the prediction it makes.
|
||||
|
||||
> Format: "If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse."
|
||||
|
||||
If you cannot state the prediction, the hypothesis is a vibe: discard or sharpen it.
|
||||
|
||||
**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly ("we just deployed a change to #3"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it; proceed with your ranking if the user is AFK.
|
||||
|
||||
## Phase 4: Instrument
|
||||
|
||||
Each probe must map to a specific prediction from Phase 3. **Change one variable at a time.**
|
||||
|
||||
Tool preference:
|
||||
|
||||
1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.
|
||||
2. **Targeted logs** at the boundaries that distinguish hypotheses.
|
||||
3. Never "log everything and grep".
|
||||
|
||||
**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.
|
||||
|
||||
**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.
|
||||
|
||||
## Phase 5: Fix + regression test
|
||||
|
||||
Write the regression test **before the fix**, but only if there is a **correct seam** for it.
|
||||
|
||||
A correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.
|
||||
|
||||
**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.
|
||||
|
||||
If a correct seam exists:
|
||||
|
||||
1. Turn the minimised repro into a failing test at that seam.
|
||||
2. Watch it fail. If you forced the red by mutating code or a fixture, `diff` against a pristine copy to prove the mutation landed before you trust it.
|
||||
3. Apply the fix.
|
||||
4. Watch it pass.
|
||||
5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.
|
||||
|
||||
## Phase 6: Cleanup
|
||||
|
||||
Required before declaring done:
|
||||
|
||||
- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)
|
||||
- [ ] Regression test passes (or absence of seam is documented)
|
||||
- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)
|
||||
- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)
|
||||
- [ ] The hypothesis that turned out correct is stated in the commit / PR message, so the next debugger learns

# Dispatching Parallel Agents
|
||||
|
||||
## Overview
|
||||
|
||||
You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
|
||||
|
||||
When you have multiple unrelated failures (different test files, different subsystems, different bugs), investigating them sequentially wastes time. Each investigation is independent and can happen in parallel.
|
||||
|
||||
**Core principle:** Dispatch one agent per independent problem domain. Let them work concurrently.
|
||||
|
||||
## When to Use
|
||||
|
||||
```dot
|
||||
digraph when_to_use {
|
||||
"Multiple failures?" [shape=diamond];
|
||||
"Are they independent?" [shape=diamond];
|
||||
"Single agent investigates all" [shape=box];
|
||||
"One agent per problem domain" [shape=box];
|
||||
"Can they work in parallel?" [shape=diamond];
|
||||
"Sequential agents" [shape=box];
|
||||
"Parallel dispatch" [shape=box];
|
||||
|
||||
"Multiple failures?" -> "Are they independent?" [label="yes"];
|
||||
"Are they independent?" -> "Single agent investigates all" [label="no - related"];
|
||||
"Are they independent?" -> "Can they work in parallel?" [label="yes"];
|
||||
"Can they work in parallel?" -> "Parallel dispatch" [label="yes"];
|
||||
"Can they work in parallel?" -> "Sequential agents" [label="no - shared state"];
|
||||
}
|
||||
```
|
||||
|
||||
**Use when:**
|
||||
- 3+ test files failing with different root causes
|
||||
- Multiple subsystems broken independently
|
||||
- Each problem can be understood without context from others
|
||||
- No shared state between investigations
|
||||
|
||||
**Don't use when:**
|
||||
- Failures are related (fix one might fix others)
|
||||
- Need to understand full system state
|
||||
- Agents would interfere with each other
|
||||
|
||||
## The Pattern
|
||||
|
||||
### 1. Identify Independent Domains
|
||||
|
||||
Group failures by what's broken:
|
||||
- File A tests: Tool approval flow
|
||||
- File B tests: Batch completion behavior
|
||||
- File C tests: Abort functionality
|
||||
|
||||
Each domain is independent - fixing tool approval doesn't affect abort tests.
|
||||
|
||||
### 2. Create Focused Agent Tasks
|
||||
|
||||
Each agent gets:
|
||||
- **Specific scope:** One test file or subsystem
|
||||
- **Clear goal:** Make these tests pass
|
||||
- **Constraints:** Don't change other code
|
||||
- **Expected output:** Summary of what you found and fixed
|
||||
|
||||
### 3. Dispatch in Parallel
|
||||
|
||||
```typescript
|
||||
// In Claude Code / AI environment
|
||||
Task("Fix agent-tool-abort.test.ts failures")
|
||||
Task("Fix batch-completion-behavior.test.ts failures")
|
||||
Task("Fix tool-approval-race-conditions.test.ts failures")
|
||||
// All three run concurrently
|
||||
```
|
||||
|
||||
### 4. Review and Integrate
|
||||
|
||||
When agents return:
|
||||
- Read each summary
|
||||
- Verify fixes don't conflict
|
||||
- Run full test suite
|
||||
- Integrate all changes
|
||||
|
||||
## Agent Prompt Structure
|
||||
|
||||
Good agent prompts are:
|
||||
1. **Focused** - One clear problem domain
|
||||
2. **Self-contained** - All context needed to understand the problem
|
||||
3. **Specific about output** - What should the agent return?
|
||||
|
||||
```markdown
|
||||
Fix the 3 failing tests in src/agents/agent-tool-abort.test.ts:
|
||||
|
||||
1. "should abort tool with partial output capture" - expects 'interrupted at' in message
|
||||
2. "should handle mixed completed and aborted tools" - fast tool aborted instead of completed
|
||||
3. "should properly track pendingToolCount" - expects 3 results but gets 0
|
||||
|
||||
These are timing/race condition issues. Your task:
|
||||
|
||||
1. Read the test file and understand what each test verifies
|
||||
2. Identify root cause - timing issues or actual bugs?
|
||||
3. Fix by:
|
||||
- Replacing arbitrary timeouts with event-based waiting
|
||||
- Fixing bugs in abort implementation if found
|
||||
- Adjusting test expectations if testing changed behavior
|
||||
|
||||
Do NOT just increase timeouts - find the real issue.
|
||||
|
||||
Return: Summary of what you found and what you fixed.
|
||||
```
|
||||
|
||||
## Common Mistakes
|
||||
|
||||
**❌ Too broad:** "Fix all the tests" - agent gets lost
|
||||
**✅ Specific:** "Fix agent-tool-abort.test.ts" - focused scope
|
||||
|
||||
**❌ No context:** "Fix the race condition" - agent doesn't know where
|
||||
**✅ Context:** Paste the error messages and test names
|
||||
|
||||
**❌ No constraints:** Agent might refactor everything
|
||||
**✅ Constraints:** "Do NOT change production code" or "Fix tests only"
|
||||
|
||||
**❌ Vague output:** "Fix it" - you don't know what changed
|
||||
**✅ Specific:** "Return summary of root cause and changes"
|
||||
|
||||
## When NOT to Use
|
||||
|
||||
**Related failures:** Fixing one might fix others - investigate together first
|
||||
**Need full context:** Understanding requires seeing entire system
|
||||
**Exploratory debugging:** You don't know what's broken yet
|
||||
**Shared state:** Agents would interfere (editing same files, using same resources)
|
||||
|
||||
## Real Example from Session
|
||||
|
||||
**Scenario:** 6 test failures across 3 files after major refactoring
|
||||
|
||||
**Failures:**
|
||||
- agent-tool-abort.test.ts: 3 failures (timing issues)
|
||||
- batch-completion-behavior.test.ts: 2 failures (tools not executing)
|
||||
- tool-approval-race-conditions.test.ts: 1 failure (execution count = 0)
|
||||
|
||||
**Decision:** Independent domains - abort logic separate from batch completion separate from race conditions
|
||||
|
||||
**Dispatch:**
|
||||
```
|
||||
Agent 1 → Fix agent-tool-abort.test.ts
|
||||
Agent 2 → Fix batch-completion-behavior.test.ts
|
||||
Agent 3 → Fix tool-approval-race-conditions.test.ts
|
||||
```
|
||||
|
||||
**Results:**
|
||||
- Agent 1: Replaced timeouts with event-based waiting
|
||||
- Agent 2: Fixed event structure bug (threadId in wrong place)
|
||||
- Agent 3: Added wait for async tool execution to complete
|
||||
|
||||
**Integration:** All fixes independent, no conflicts, full suite green
|
||||
|
||||
**Time saved:** 3 problems solved in parallel vs sequentially
|
||||
|
||||
## Key Benefits
|
||||
|
||||
1. **Parallelization** - Multiple investigations happen simultaneously
|
||||
2. **Focus** - Each agent has narrow scope, less context to track
|
||||
3. **Independence** - Agents don't interfere with each other
|
||||
4. **Speed** - 3 problems solved in time of 1
|
||||
|
||||
## Verification
|
||||
|
||||
After agents return:
|
||||
1. **Review each summary** - Understand what changed
|
||||
2. **Check for conflicts** - Did agents edit same code?
|
||||
3. **Run full suite** - Verify all fixes work together
|
||||
4. **Spot check** - Agents can make systematic errors
|
||||
|
||||
## Real-World Impact
|
||||
|
||||
From debugging session (2025-10-03):
|
||||
- 6 failures across 3 files
|
||||
- 3 agents dispatched in parallel
|
||||
- All investigations completed concurrently
|
||||
- All fixes integrated successfully
|
||||
- Zero conflicts between agent changes

# ADR Format
|
||||
|
||||
ADRs live in `docs/adr/` and use sequential numbering: `0001-slug.md`, `0002-slug.md`, etc.
|
||||
|
||||
Create the `docs/adr/` directory lazily: only when the first ADR is needed.
|
||||
|
||||
## Template
|
||||
|
||||
```md
|
||||
# {Short title of the decision}
|
||||
|
||||
{1-3 sentences: what's the context, what did we decide, and why.}
|
||||
```
|
||||
|
||||
That's it. An ADR can be a single paragraph. The value is in recording *that* a decision was made and *why*, not in filling out sections.
|
||||
|
||||
## Optional sections
|
||||
|
||||
Only include these when they add genuine value. Most ADRs won't need them.
|
||||
|
||||
- **Status** frontmatter (`proposed | accepted | deprecated | superseded by ADR-NNNN`): useful when decisions are revisited
|
||||
- **Considered Options**: only when the rejected alternatives are worth remembering
|
||||
- **Consequences**: only when non-obvious downstream effects need to be called out
|
||||
|
||||
## Numbering
|
||||
|
||||
Scan `docs/adr/` for the highest existing number and increment by one.
|
||||
|
||||
## When to offer an ADR
|
||||
|
||||
All three of these must be true:
|
||||
|
||||
1. **Hard to reverse**: the cost of changing your mind later is meaningful
|
||||
2. **Surprising without context**: a future reader will look at the code and wonder "why on earth did they do it this way?"
|
||||
3. **The result of a real trade-off**: there were genuine alternatives and you picked one for specific reasons
|
||||
|
||||
If a decision is easy to reverse, skip it: you'll just reverse it. If it's not surprising, nobody will wonder why. If there was no real alternative, there's nothing to record beyond "we did the obvious thing."
|
||||
|
||||
### What qualifies
|
||||
|
||||
- **Architectural shape.** "We're using a monorepo." "The write model is event-sourced, the read model is projected into Postgres."
|
||||
- **Integration patterns between contexts.** "Ordering and Billing communicate via domain events, not synchronous HTTP."
|
||||
- **Technology choices that carry lock-in.** Database, message bus, auth provider, deployment target. Not every library: just the ones that would take a quarter to swap out.
|
||||
- **Boundary and scope decisions.** "Customer data is owned by the Customer context; other contexts reference it by ID only." The explicit no-s are as valuable as the yes-s.
|
||||
- **Deliberate deviations from the obvious path.** "We're using manual SQL instead of an ORM because X." Anything where a reasonable reader would assume the opposite. These stop the next engineer from "fixing" something that was deliberate.
|
||||
- **Constraints not visible in the code.** "We can't use AWS because of compliance requirements." "Response times must be under 200ms because of the partner API contract."
|
||||
- **Rejected alternatives when the rejection is non-obvious.** If you considered GraphQL and picked REST for subtle reasons, record it; otherwise someone will suggest GraphQL again in six months.

# GLOSSARY.md Format
|
||||
|
||||
## Structure
|
||||
|
||||
```md
|
||||
# {Context Name}
|
||||
|
||||
{One or two sentence description of what this context is and why it exists.}
|
||||
|
||||
## Language
|
||||
|
||||
**Order**:
|
||||
{A one or two sentence description of the term}
|
||||
_Avoid_: Purchase, transaction
|
||||
|
||||
**Invoice**:
|
||||
A request for payment sent to a customer after delivery.
|
||||
_Avoid_: Bill, payment request
|
||||
|
||||
**Customer**:
|
||||
A person or organization that places orders.
|
||||
_Avoid_: Client, buyer, account
|
||||
```
|
||||
|
||||
## Rules
|
||||
|
||||
- **Be opinionated.** When multiple words exist for the same concept, pick the best one and list the others under `_Avoid_`.
|
||||
- **Keep definitions tight.** One or two sentences max. Define what it IS, not what it does.
|
||||
- **Only include terms specific to this project's context.** General programming concepts (timeouts, error types, utility patterns) don't belong even if the project uses them extensively. Before adding a term, ask: is this a concept unique to this context, or a general programming concept? Only the former belongs.
|
||||
- **Group terms under subheadings** when natural clusters emerge. If all terms belong to a single cohesive area, a flat list is fine.
|
||||
|
||||
## Single vs multi-context repos
|
||||
|
||||
**Single context (most repos):** One `GLOSSARY.md` at the repo root.
|
||||
|
||||
**Multiple contexts:** A `GLOSSARY-MAP.md` at the repo root lists the contexts, where they live, and how they relate to each other:
|
||||
|
||||
```md
|
||||
# Glossary Map
|
||||
|
||||
## Contexts
|
||||
|
||||
- [Ordering](./src/ordering/GLOSSARY.md): receives and tracks customer orders
|
||||
- [Billing](./src/billing/GLOSSARY.md): generates invoices and processes payments
|
||||
- [Fulfillment](./src/fulfillment/GLOSSARY.md): manages warehouse picking and shipping
|
||||
|
||||
## Relationships
|
||||
|
||||
- **Ordering → Fulfillment**: Ordering emits `OrderPlaced` events; Fulfillment consumes them to start picking
|
||||
- **Fulfillment → Billing**: Fulfillment emits `ShipmentDispatched` events; Billing consumes them to generate invoices
|
||||
- **Ordering ↔ Billing**: Shared types for `CustomerId` and `Money`
|
||||
```
|
||||
|
||||
The skill infers which structure applies:
|
||||
|
||||
- If `GLOSSARY-MAP.md` exists, read it to find contexts
|
||||
- If only a root `GLOSSARY.md` exists, single context
|
||||
- If neither exists, create a root `GLOSSARY.md` lazily when the first term is resolved
|
||||
|
||||
When multiple contexts exist, infer which one the current topic relates to. If unclear, ask.

# Domain Modeling
|
||||
|
||||
Actively build and sharpen the project's domain model as you design. This is the *active* discipline: challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallise. (Merely *reading* `GLOSSARY.md` for vocabulary is not this skill: that's a one-line habit any skill can do. This skill is for when you're changing the model, not just consuming it.)
|
||||
|
||||
## File structure
|
||||
|
||||
Most repos have a single context:
|
||||
|
||||
```
|
||||
/
|
||||
├── GLOSSARY.md
|
||||
├── docs/
|
||||
│ └── adr/
|
||||
│ ├── 0001-event-sourced-orders.md
|
||||
│ └── 0002-postgres-for-write-model.md
|
||||
└── src/
|
||||
```
|
||||
|
||||
If a `GLOSSARY-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives:
|
||||
|
||||
```
|
||||
/
|
||||
├── GLOSSARY-MAP.md
|
||||
├── docs/
|
||||
│ └── adr/ ← system-wide decisions
|
||||
├── src/
|
||||
│ ├── ordering/
|
||||
│ │ ├── GLOSSARY.md
|
||||
│ │ └── docs/adr/ ← context-specific decisions
|
||||
│ └── billing/
|
||||
│ ├── GLOSSARY.md
|
||||
│ └── docs/adr/
|
||||
```
|
||||
|
||||
Create files lazily: only when you have something to write. If no `GLOSSARY.md` exists, create one when the first term is resolved. If no `docs/adr/` exists, create it when the first ADR is needed.
|
||||
|
||||
## During the session
|
||||
|
||||
### Challenge against the glossary
|
||||
|
||||
When the user uses a term that conflicts with the existing language in `GLOSSARY.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y. Which is it?"
|
||||
|
||||
### Sharpen fuzzy language
|
||||
|
||||
When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account': do you mean the Customer or the User? Those are different things."
|
||||
|
||||
### Discuss concrete scenarios
|
||||
|
||||
When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts.
|
||||
|
||||
### Cross-reference with code
|
||||
|
||||
When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible. Which is right?"
|
||||
|
||||
### Update GLOSSARY.md inline
|
||||
|
||||
When a term is resolved, update `GLOSSARY.md` right there. Don't batch these up: capture them as they happen. Use the format in [GLOSSARY-FORMAT.md](./GLOSSARY-FORMAT.md).
|
||||
|
||||
`GLOSSARY.md` should be totally devoid of implementation details. Do not treat `GLOSSARY.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else.
|
||||
|
||||
### Offer ADRs sparingly
|
||||
|
||||
Only offer to create an ADR when all three are true:
|
||||
|
||||
1. **Hard to reverse**: the cost of changing your mind later is meaningful
|
||||
2. **Surprising without context**: a future reader will wonder "why did they do it this way?"
|
||||
3. **The result of a real trade-off**: there were genuine alternatives and you picked one for specific reasons
|
||||
|
||||
If any of the three is missing, skip the ADR. Use the format in [ADR-FORMAT.md](./ADR-FORMAT.md).

# Executing Plans
|
||||
|
||||
## Overview
|
||||
|
||||
Load plan, review critically, execute all tasks, report when complete.
|
||||
|
||||
**Announce at start:** "I'm using the executing-plans skill to implement this plan."
|
||||
|
||||
**Note:** Tell your human partner that Superpowers works much better with access to subagents. The quality of its work will be significantly higher if run on a platform with subagent support (such as Claude Code or Codex). If subagents are available, use superpowers:subagent-driven-development instead of this skill.
|
||||
|
||||
## The Process
|
||||
|
||||
### Step 1: Load and Review Plan
|
||||
1. Read plan file
|
||||
2. Review critically - identify any questions or concerns about the plan
|
||||
3. If concerns: Raise them with your human partner before starting
|
||||
4. If no concerns: Create TodoWrite and proceed
|
||||
|
||||
### Step 2: Execute Tasks
|
||||
|
||||
For each task:
|
||||
1. Mark as in_progress
|
||||
2. Follow each step exactly (plan has bite-sized steps)
|
||||
3. Run verifications as specified
|
||||
4. Mark as completed
|
||||
|
||||
### Step 3: Complete Development
|
||||
|
||||
After all tasks complete and verified:
|
||||
- Announce: "I'm using the finishing-a-development-branch skill to complete this work."
|
||||
- **REQUIRED SUB-SKILL:** Use superpowers:finishing-a-development-branch
|
||||
- Follow that skill to verify tests, present options, execute choice
|
||||
|
||||
## When to Stop and Ask for Help
|
||||
|
||||
**STOP executing immediately when:**
|
||||
- Hit a blocker (missing dependency, test fails, instruction unclear)
|
||||
- Plan has critical gaps preventing starting
|
||||
- You don't understand an instruction
|
||||
- Verification fails repeatedly
|
||||
|
||||
**Ask for clarification rather than guessing.**
|
||||
|
||||
## When to Revisit Earlier Steps
|
||||
|
||||
**Return to Review (Step 1) when:**
|
||||
- Partner updates the plan based on your feedback
|
||||
- Fundamental approach needs rethinking
|
||||
|
||||
**Don't force through blockers** - stop and ask.
|
||||
|
||||
## Remember
|
||||
- Review plan critically first
|
||||
- Follow plan steps exactly
|
||||
- Don't skip verifications
|
||||
- Reference skills when plan says to
|
||||
- Stop when blocked, don't guess
|
||||
- Never start implementation on main/master branch without explicit user consent
|
||||
|
||||
## Integration
|
||||
|
||||
**Required workflow skills:**
|
||||
- **superpowers:using-git-worktrees** - Ensures isolated workspace (creates one or verifies existing)
|
||||
- **superpowers:writing-plans** - Creates the plan this skill executes
|
||||
- **superpowers:finishing-a-development-branch** - Complete development after all tasks

||||
|
||||
**Before presenting options, verify tests pass:**
|
||||
|
||||
```bash
|
||||
# Run project's test suite
|
||||
npm test / cargo test / pytest / go test ./...
|
||||
```
|
||||
|
||||
**If tests fail:**
|
||||
```
|
||||
Tests failing (<N> failures). Must fix before completing:
|
||||
|
||||
[Show failures]
|
||||
|
||||
Cannot proceed with merge/PR until tests pass.
|
||||
```
|
||||
|
||||
Stop. Don't proceed to Step 2.
|
||||
|
||||
**If tests pass:** Continue to Step 2.
|
||||
|
||||
### Step 2: Detect Environment
|
||||
|
||||
**Determine workspace state before presenting options:**
|
||||
|
||||
```bash
|
||||
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
|
||||
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
|
||||
```
|
||||
|
||||
This determines which menu to show and how cleanup works:
|
||||
|
||||
| State | Menu | Cleanup |
|
||||
|-------|------|---------|
|
||||
| `GIT_DIR == GIT_COMMON` (normal repo) | Standard 4 options | No worktree to clean up |
|
||||
| `GIT_DIR != GIT_COMMON`, named branch | Standard 4 options | Provenance-based (see Step 6) |
|
||||
| `GIT_DIR != GIT_COMMON`, detached HEAD | Reduced 3 options (no merge) | No cleanup (externally managed) |
|
||||
|
||||
### Step 3: Determine Base Branch
|
||||
|
||||
```bash
|
||||
# Try common base branches
|
||||
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
|
||||
```
|
||||
|
||||
Or ask: "This branch split from main - is that correct?"
|
||||
|
||||
### Step 4: Present Options
|
||||
|
||||
**Normal repo and named-branch worktree — present exactly these 4 options:**
|
||||
|
||||
```
|
||||
Implementation complete. What would you like to do?
|
||||
|
||||
1. Merge back to <base-branch> locally
|
||||
2. Push and create a Pull Request
|
||||
3. Keep the branch as-is (I'll handle it later)
|
||||
4. Discard this work
|
||||
|
||||
Which option?
|
||||
```
|
||||
|
||||
**Detached HEAD — present exactly these 3 options:**
|
||||
|
||||
```
|
||||
Implementation complete. You're on a detached HEAD (externally managed workspace).
|
||||
|
||||
1. Push as new branch and create a Pull Request
|
||||
2. Keep as-is (I'll handle it later)
|
||||
3. Discard this work
|
||||
|
||||
Which option?
|
||||
```
|
||||
|
||||
**Don't add explanation** - keep options concise.
|
||||
|
||||
### Step 5: Execute Choice
|
||||
|
||||
#### Option 1: Merge Locally
|
||||
|
||||
```bash
|
||||
# Get main repo root for CWD safety
|
||||
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
|
||||
cd "$MAIN_ROOT"
|
||||
|
||||
# Merge first — verify success before removing anything
|
||||
git checkout <base-branch>
|
||||
git pull
|
||||
git merge <feature-branch>
|
||||
|
||||
# Verify tests on merged result
|
||||
<test command>
|
||||
|
||||
# Only after merge succeeds: cleanup worktree (Step 6), then delete branch
|
||||
```
|
||||
|
||||
Then: Cleanup worktree (Step 6), then delete branch:
|
||||
|
||||
```bash
|
||||
git branch -d <feature-branch>
|
||||
```
|
||||
|
||||
#### Option 2: Push and Create PR
|
||||
|
||||
```bash
|
||||
# Push branch
|
||||
git push -u origin <feature-branch>
|
||||
|
||||
# Create PR
|
||||
gh pr create --title "<title>" --body "$(cat <<'EOF'
|
||||
## Summary
|
||||
<2-3 bullets of what changed>
|
||||
|
||||
## Test Plan
|
||||
- [ ] <verification steps>
|
||||
EOF
|
||||
)"
|
||||
```
|
||||
|
||||
**Do NOT clean up worktree** — user needs it alive to iterate on PR feedback.
|
||||
|
||||
#### Option 3: Keep As-Is
|
||||
|
||||
Report: "Keeping branch <name>. Worktree preserved at <path>."
|
||||
|
||||
**Don't cleanup worktree.**
|
||||
|
||||
#### Option 4: Discard
|
||||
|
||||
**Confirm first:**
|
||||
```
|
||||
This will permanently delete:
|
||||
- Branch <name>
|
||||
- All commits: <commit-list>
|
||||
- Worktree at <path>
|
||||
|
||||
Type 'discard' to confirm.
|
||||
```
|
||||
|
||||
Wait for exact confirmation.
|
||||
|
||||
If confirmed:
|
||||
```bash
|
||||
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
|
||||
cd "$MAIN_ROOT"
|
||||
```
|
||||
|
||||
Then: Cleanup worktree (Step 6), then force-delete branch:
|
||||
```bash
|
||||
git branch -D <feature-branch>
|
||||
```
|
||||
|
||||
### Step 6: Cleanup Workspace
|
||||
|
||||
**Only runs for Options 1 and 4.** Options 2 and 3 always preserve the worktree.
|
||||
|
||||
```bash
|
||||
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
|
||||
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
|
||||
WORKTREE_PATH=$(git rev-parse --show-toplevel)
|
||||
```
|
||||
|
||||
**If `GIT_DIR == GIT_COMMON`:** Normal repo, no worktree to clean up. Done.
|
||||
|
||||
**If worktree path is under `.worktrees/`, `worktrees/`, or `~/.config/superpowers/worktrees/`:** Superpowers created this worktree — we own cleanup.
|
||||
|
||||
```bash
|
||||
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
|
||||
cd "$MAIN_ROOT"
|
||||
git worktree remove "$WORKTREE_PATH"
|
||||
git worktree prune # Self-healing: clean up any stale registrations
|
||||
```
|
||||
|
||||
**Otherwise:** The host environment (harness) owns this workspace. Do NOT remove it. If your platform provides a workspace-exit tool, use it. Otherwise, leave the workspace in place.
|
||||
|
||||
## Quick Reference
|
||||

|
||||
## Common Mistakes
|
||||
|
||||
**Skipping test verification**
|
||||
- **Problem:** Merge broken code, create failing PR
|
||||
- **Fix:** Always verify tests before offering options
|
||||
|
||||
**Open-ended questions**
|
||||
- **Problem:** "What should I do next?" is ambiguous
|
||||
- **Fix:** Present exactly 4 structured options (or 3 for detached HEAD)
|
||||
|
||||
**Cleaning up worktree for Option 2**
|
||||
- **Problem:** Remove worktree user needs for PR iteration
|
||||
- **Fix:** Only cleanup for Options 1 and 4
|
||||
|
||||
**Deleting branch before removing worktree**
|
||||
- **Problem:** `git branch -d` fails because worktree still references the branch
|
||||
- **Fix:** Merge first, remove worktree, then delete branch
|
||||
|
||||
**Running git worktree remove from inside the worktree**
|
||||
- **Problem:** Command fails silently when CWD is inside the worktree being removed
|
||||
- **Fix:** Always `cd` to main repo root before `git worktree remove`
|
||||
|
||||
**Cleaning up harness-owned worktrees**
|
||||
- **Problem:** Removing a worktree the harness created causes phantom state
|
||||
- **Fix:** Only clean up worktrees under `.worktrees/`, `worktrees/`, or `~/.config/superpowers/worktrees/`
|
||||
|
||||
**No confirmation for discard**
|
||||
- **Problem:** Accidentally delete work
|
||||
- **Fix:** Require typed "discard" confirmation
|
||||
|
||||
## Red Flags
|
||||
|
||||
**Never:**
|
||||
- Proceed with failing tests
|
||||
- Merge without verifying tests on result
|
||||
- Delete work without confirmation
|
||||
- Force-push without explicit request
|
||||
- Remove a worktree before confirming merge success
|
||||
- Clean up worktrees you didn't create (provenance check)
|
||||
- Run `git worktree remove` from inside the worktree
|
||||
|
||||
**Always:**
|
||||
- Verify tests before offering options
|
||||
- Detect environment before presenting menu
|
||||
- Present exactly 4 options (or 3 for detached HEAD)
|
||||
- Get typed confirmation for Option 4
|
||||
- Clean up worktree for Options 1 & 4 only
|
||||
- `cd` to main repo root before worktree removal
|
||||
- Run `git worktree prune` after removal

|

---
|
||||
|
||||
Interview the user relentlessly until you reach a shared understanding. Map this as a **design tree**: every decision branches into the decisions that hang off it.
|
||||
|
||||
Work the tree in **rounds**. The **frontier** is every decision whose prerequisites are already settled: the questions you can ask _now_ without guessing at answers you haven't heard yet. Ask the whole frontier in one round: number each question and give your recommended answer. Then wait for the user's answers before the next round.
|
||||
|
||||
Format a round like so:
|
||||
|
||||
```
|
||||
❓ **Q1** - **<question title>**: <question body, might be multiple paragraphs, including multiple choices>
|
||||
|
||||
➡️ <your recommended answer>
|
||||

||||

|
||||
|
||||
❓ **Q2** - **<question title>**: <question body, might be multiple paragraphs, including multiple choices>
|
||||
|
||||
➡️ <your recommended answer>
|
||||
```
|
||||
|
||||
Word each question so "yes" accepts your recommended answer.
|
||||
|
||||
Each round the user answers reshapes the tree: settled decisions push the frontier outward and unblock questions that depended on them. Recompute the frontier and ask the next round. A question whose answer depends on another question still open in this round belongs to a _later_ round, not this one.
|
||||
|
||||
Finding _facts_ is your job, never the user's. When a frontier question needs a fact from the environment (filesystem, tools, etc.), dispatch a sub-agent with a fresh context window to find it; don't ask the user for anything you could look up yourself. Don't block on it: a running exploration is an unsettled prerequisite, so only the questions downstream of it wait for the sub-agent to report; ask the rest of the frontier now. The _decisions_ are the user's: put each to them and wait.
|
||||
|
||||
The session is done when the frontier is empty: every branch of the design tree visited, nothing left silently assumed. Do not act on it until the user confirms you have reached a shared understanding.

|

disable-model-invocation: true
|

---
|
||||
|
||||
You have been provided a spec. This spec should have tickets associated with it, describing how to implement the spec.
|
||||
|
||||
The issue tracker should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
|
||||
|
||||
The goal is the entire spec implemented on a single **integration branch**, with every ticket resolved the way the issue tracker closes work.
|
||||
|
||||
The tickets are not a list of steps. They are a **task graph** with blocking relationships between them. This means there is always a **frontier** of tickets which are ready to be grabbed.
|
||||
|
||||
Start every subagent with a fresh context window.
|
||||
|
||||
Communication to and from subagents should be sparse. Communicate primarily through **context pointers**: to the spec, tickets, research notes, and previous commits. Don't duplicate information already available via pointers.
|
||||
|
||||
**Implementer subagents** should be run in the background where possible for maximum concurrency.
|
||||
|
||||
## Steps
|
||||
|
||||
1. Read the spec and tickets to understand the task graph.
|
||||
|
||||
2. (optional) Use an **exploration subagent** to conduct any exploration required by the tickets - relevant codebase files or external documentation. Ensure the exploration subagent can save files - it should save its markdown notes in a directory outside the repo, accessible by all future subagents. This lets **implementer subagents** focus on implementation rather than exploration.
|
||||
|
||||
3. Create the integration branch. If the issue tracker closes work through PRs, or the user asks for one, open a draft PR after the first merge in step 5 (a branch with no commits ahead of main can't open one), marked as closing the spec and tickets.
|
||||
|
||||
4. Use a fresh **implementer subagent** for each ticket, each in its own worktree on its own branch. Each implementer subagent:
|
||||
- confirms its worktree is based on the integration branch before starting, and resets onto it if not;
|
||||
- calls the Skill tool with `tdd` to build the ticket;
|
||||
- merges the integration branch tip into its own branch before reporting done
|
||||
|
||||
5. Once an **implementer subagent** completes, merge its work to the integration branch with a **merger subagent**.
|
||||
|
||||
6. If this changes the **frontier** of available tickets, kick off more **implementer subagents** to work on the new tickets. This allows for maximum concurrency.
|
||||
|
||||
7. Once all tickets are complete, call the Skill tool with `code-review` on the integration branch. Fix all issues raised by the code review in a single fresh **implementer subagent**.
|
||||
|
||||
8. If a draft PR exists, mark it ready for review. Otherwise, resolve each ticket the way the issue tracker closes work, and report the integration branch.
|
||||
|
||||
9. Clean up all **implementer subagent** worktrees.

# HTML Report Format
|
||||
|
||||
The architectural review is rendered as a single self-contained HTML file in the OS temp directory. Tailwind and Mermaid both come from CDNs. Mermaid handles graph-shaped diagrams reliably; hand-built divs and inline SVG handle the more editorial visuals (mass diagrams, cross-sections). Mix the two: don't lean on Mermaid for everything, it'll start to look generic.
|
||||
|
||||
## Scaffold
|
||||
|
||||
```html

||||

||||
<html lang="en">

```
|
||||
|
||||
## Header
|
||||
|
||||
Repo name, date, and a compact legend: solid box = module, dashed line = seam, red arrow = leakage, thick dark box = deep module. No introduction paragraph. Straight into the candidates.
|
||||
|
||||
## Candidate card
|
||||
|
||||
The diagrams carry the weight. Prose is sparse, plain, and uses the glossary terms (from the `/codebase-design` skill) without ceremony.
|
||||
|
||||
Each candidate is one `<article>`:
|
||||
|
||||
- **Title**: short, names the deepening (e.g. "Collapse the Order intake pipeline").
|
||||
- **Badge row**: recommendation strength (`Strong` = emerald, `Worth exploring` = amber, `Speculative` = slate), plus a tag for the dependency category (`in-process`, `local-substitutable`, `ports & adapters`, `mock`).
|
||||
- **Files**: monospaced list, `font-mono text-sm`.
|
||||
- **Before / After diagram**: the centrepiece. Two columns, side by side. See patterns below.
|
||||
- **Problem**: one sentence. What hurts.
|
||||
- **Solution**: one sentence. What changes.
|
||||
- **Wins**: bullets, ≤6 words each. e.g. "Tests hit one interface", "Pricing logic stops leaking", "Delete 4 shallow wrappers".
|
||||
- **ADR callout** (if applicable): one line in an amber-tinted box.
|
||||
|
||||
No paragraphs of explanation. If the diagram needs a paragraph to be understood, redraw the diagram.
|
||||
|
||||
## Diagram patterns
|
||||
|
||||
Pick the pattern that fits the candidate. Mix them. Don't make every diagram look the same. Variety is part of the point.
|
||||
|
||||
### Mermaid graph (the workhorse for dependencies / call flow)
|
||||
|
||||
Use a Mermaid `flowchart` or `graph` when the point is "X calls Y calls Z, and look at the mess." Wrap it in a Tailwind-styled card so it doesn't feel parachuted in. Style with classDef to colour leakage edges red and the deep module dark. Sequence diagrams work well for "before: 6 round-trips; after: 1."

### Hand-built boxes-and-arrows (when Mermaid's layout fights you)
|
||||
|
||||
Modules as `<div>`s with borders and labels. Arrows as inline SVG `<line>` or `<path>` elements positioned absolutely over a relative container. Reach for this when you want the "after" diagram to feel like one thick-bordered deep module with greyed-out internals, since Mermaid won't render that with the right weight.
|
||||
|
||||
### Cross-section (good for layered shallowness)
|
||||
|
||||
Stack horizontal bands (`h-12 border-l-4`) to show layers a call passes through. Before: 6 thin layers each doing nothing. After: 1 thick band labelled with the consolidated responsibility.
|
||||
|
||||
### Mass diagram (good for "interface as wide as implementation")
|
||||
|
||||
Two rectangles per module: one for interface surface area, one for implementation. Before: interface rectangle is nearly as tall as the implementation rectangle (shallow). After: interface rectangle is short, implementation rectangle is tall (deep).
|
||||
|
||||
### Call-graph collapse
|
||||
|
||||
Before: a tree of function calls rendered as nested boxes. After: the same tree collapsed into one box, with the now-internal calls shown faded inside it.
|
||||
|
||||
## Style guidance
|
||||
|
||||
- Lean editorial, not corporate-dashboard. Generous whitespace. Serif optional for headings (`font-serif` works well with stone/slate).
|
||||
- Colour sparingly: one accent (emerald or indigo) plus red for leakage and amber for warnings.
|
||||
- Keep diagrams ~320px tall so before/after sits comfortably side by side without scrolling.
|
||||
- Use `text-xs uppercase tracking-wider` for module labels inside diagrams, so they read as schematic, not as UI.
|
||||
- The only scripts are the Tailwind CDN and the Mermaid ESM import. The report is otherwise static: no app code, no interactivity beyond Mermaid's own rendering.
|
||||
|
||||
## Top recommendation section
|
||||
|
||||
One larger card. Candidate name, one sentence on why, anchor link to its card. That's it.
|
||||
|
||||
## Tone
|
||||
|
||||
Plain English, concise, but the architectural nouns and verbs come straight from the `/codebase-design` skill. Concision is not an excuse to drift.
|
||||
|
||||
**Use exactly:** module, interface, implementation, depth, deep, shallow, seam, adapter, leverage, locality.
|
||||
|
||||
**Never substitute:** component, service, unit (for module) · API, signature (for interface) · boundary (for seam) · layer, wrapper (for module, when you mean module).
|
||||
|
||||
**Phrasings that fit the style:**
|
||||
|
||||
- "Order intake module is shallow: interface nearly matches the implementation."
|
||||
- "Pricing leaks across the seam."
|
||||
- "Deepen: one interface, one place to test."
|
||||
- "Two adapters justify the seam: HTTP in prod, in-memory in tests."
|
||||
|
||||
**Wins bullets** name the gain in glossary terms: *"locality: bugs concentrate in one module"*, *"leverage: one interface, N call sites"*, *"interface shrinks; implementation absorbs the wrappers"*. Don't write *"easier to maintain"* or *"cleaner code"*, because those terms aren't in the glossary and don't earn their place.
|
||||
|
||||
No hedging, no throat-clearing, no "it's worth noting that…". If a sentence could be a bullet, make it a bullet. If a bullet could be cut, cut it. If a term isn't in the `/codebase-design` glossary, reach for one that is before inventing a new one.

# Improve Codebase Architecture
|
||||
|
||||
Surface architectural friction and propose **deepening opportunities**: refactors that turn shallow modules into deep ones. The aim is testability and AI-navigability.
|
||||
|
||||
This command is _informed_ by the project's domain model and built on a shared design vocabulary:
|
||||
|
||||
- Call the Skill tool with "codebase-design" for the architecture vocabulary (**module**, **interface**, **depth**, **seam**, **adapter**, **leverage**, **locality**) and its principles (the deletion test, "the interface is the test surface", "one adapter = hypothetical seam, two = real"). Use these terms exactly in every suggestion, and don't drift into "component," "service," "API," or "boundary."
|
||||
- The domain language in `GLOSSARY.md` gives names to good seams; ADRs in `docs/adr/` record decisions this command should not re-litigate.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. Explore
|
||||
|
||||
**Scope before you scan: YAGNI.** Deepening a module pays off by making future changes to it easier, so put extra weight on the parts of the codebase that have recently changed. Decide *where* to look before you look:
|
||||
|
||||
- If the user named a direction (a module, a subsystem, a pain point), take it, and skip the inference below.
|
||||
- Otherwise, walk back a good stretch of the commit history (`git log --oneline`) to find the codebase's hot spots, the files and areas that keep coming up, and let those paths pull your attention first. If the changes are scattered with no clear hot spot, widen the net.
|
||||
|
||||
Read the project's domain glossary (`GLOSSARY.md`) and any ADRs in the area you're touching first.
|
||||
|
||||
Then spawn a sub-agent with a fresh context window to walk the codebase. Don't follow rigid heuristics; explore organically and note where you experience friction:
|
||||
|
||||
- Where does understanding one concept require bouncing between many small modules?
|
||||
- Where are modules **shallow**, with an interface nearly as complex as the implementation?
|
||||
- Where have pure functions been extracted just for testability, but the real bugs hide in how they're called (no **locality**)?
|
||||
- Where do tightly-coupled modules leak across their seams?
|
||||
- Which parts of the codebase are untested, or hard to test through their current interface?
|
||||
|
||||
Apply the **deletion test** to anything you suspect is shallow: would deleting it concentrate complexity, or just move it? A "yes, concentrates" is the signal you want.
|
||||
|
||||
### 2. Present candidates as an HTML report
|
||||
|
||||
Write a self-contained HTML file to the OS temp directory so nothing lands in the repo. Resolve the temp dir from `$TMPDIR`, falling back to `/tmp` (or `%TEMP%` on Windows), and write to `<tmpdir>/architecture-review-<timestamp>.html` so each run gets a fresh file. Open it for the user (`xdg-open <path>` on Linux, `open <path>` on macOS, `start <path>` on Windows) and tell them the absolute path.
|
||||
|
||||
The report uses **Tailwind via CDN** for layout and styling, and **Mermaid via CDN** for diagrams where a graph/flow/sequence reliably communicates the structure. Mix Mermaid with hand-crafted CSS/SVG visuals: use Mermaid when relationships are graph-shaped (call graphs, dependencies, sequences), and hand-built divs/SVG when you want something more editorial (mass diagrams, cross-sections, collapse animations). Each candidate gets a **before/after visualisation**. Be visual.
|
||||
|
||||
For each candidate, render a card with:
|
||||
|
||||
- **Files**: which files/modules are involved
|
||||
- **Problem**: why the current architecture is causing friction
|
||||
- **Solution**: plain English description of what would change
|
||||
- **Benefits**: explained in terms of locality and leverage, and how tests would improve
|
||||
- **Before / After diagram**: side-by-side, custom-drawn, illustrating the shallowness and the deepening
|
||||
- **Recommendation strength**: one of `Strong`, `Worth exploring`, `Speculative`, rendered as a badge
|
||||
|
||||
End the report with a **Top recommendation** section: which candidate you'd tackle first and why.
|
||||
|
||||
**Use GLOSSARY.md vocabulary for the domain, and the `/codebase-design` vocabulary for the architecture.** If `GLOSSARY.md` defines "Order," talk about "the Order intake module," not "the FooBarHandler," and not "the Order service."
|
||||
|
||||
**ADR conflicts**: if a candidate contradicts an existing ADR, only surface it when the friction is real enough to warrant revisiting the ADR. Mark it clearly in the card (e.g. a warning callout: _"contradicts ADR-0007, but worth reopening because…"_). Don't list every theoretical refactor an ADR forbids.
|
||||
|
||||
See [HTML-REPORT.md](HTML-REPORT.md) for the full HTML scaffold, diagram patterns, and styling guidance.
|
||||
|
||||
Do NOT propose interfaces yet. After the file is written, ask the user: "Which of these would you like to explore?"
|
||||
|
||||
### 3. Grilling loop
|
||||
|
||||
Once the user picks a candidate, call the Skill tool with "grilling" to walk the decision tree with them: constraints, dependencies, the shape of the deepened module, what sits behind the seam, what tests survive.
|
||||
|
||||
Side effects happen inline as decisions crystallize; call the Skill tool with "domain-modeling" to keep the domain model current as you go:
|
||||
|
||||
- **Naming a deepened module after a concept not in `GLOSSARY.md`?** Add the term to `GLOSSARY.md`. Create the file lazily if it doesn't exist.
|
||||
- **Sharpening a fuzzy term during the conversation?** Update `GLOSSARY.md` right there.
|
||||
- **User rejects the candidate with a load-bearing reason?** Offer an ADR, framed as: _"Want me to record this as an ADR so future architecture reviews don't re-suggest it?"_ Only offer when the reason would actually be needed by a future explorer to avoid re-suggesting the same thing; skip ephemeral reasons ("not worth it right now") and self-evident ones.
|
||||
- **Want to explore alternative interfaces for the deepened module?** Call the Skill tool with "codebase-design" and use its design-it-twice parallel sub-agent pattern.

### Summary
|
||||
|
||||
Pick the smallest view that makes the key point clear.
|
||||
|
||||
- Show logic or an algorithm as pseudocode:
|
||||
|
||||
```text
|
||||
on(save)
|
||||
if content is unchanged
|
||||
return cached result
|
||||
write new content
|
||||
return fresh result
|
||||
```
|
||||
|
||||
- Show runtime control flow as a call tree:
|
||||
|
||||
```text
|
||||
submitForm
|
||||
createSession
|
||||
persistPrompt
|
||||
launchAgent
|
||||
navigateToSession
|
||||
```
|
||||
|
||||
- Show UI structure as a component tree, including state and module boundaries that matter:
|
||||
|
||||
```text
|
||||
<SessionPage> (apps/example/src/routes/session.tsx)
|
||||
useSessionEvents()
|
||||
<SessionToolbar>
|
||||
<RunSkillButton> (packages/ui)
|
||||
```
|
||||
|
||||
- Show file responsibility or a broad refactor as a shallow file tree:
|
||||
|
||||
```text
|
||||
src/
|
||||
├── commands/ # parses user actions
|
||||
├── sessions/ # owns session state
|
||||
└── transport/ # sends API requests
|
||||
```
|
||||
|
||||
- Show component interaction, control flow, or data flow with Mermaid:
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
participant User
|
||||
participant UI
|
||||
participant Daemon
|
||||
User->>UI: choose command
|
||||
UI->>Daemon: send expanded prompt
|
||||
Daemon-->>UI: stream result
|
||||
```
|
||||
|
||||
- Use `diff` when the point is what changes and the surrounding shape already exists. Match the diff shape to the topic.
|
||||
|
||||
For a component change:
|
||||
|
||||
```diff
|
||||
<SessionPage>
|
||||
useSessionEvents()
|
||||
<SessionToolbar>
|
||||
+ <RunSkillButton />
|
||||
<SessionTimeline>
|
||||
+ <SkillResultCard />
|
||||
```
|
||||
|
||||
For a file-layout change:
|
||||
|
||||
```diff
|
||||
src/
|
||||
├── commands/
|
||||
+│ └── show-me.ts # expands the slash command
|
||||
├── sessions/
|
||||
-└── transport.ts
|
||||
+└── transport/
|
||||
+ ├── client.ts
|
||||
+ └── stream.ts
|
||||
```
|
||||
|
||||
For a call-tree or call-stack change:
|
||||
|
||||
```diff
|
||||
submitForm
|
||||
createSession
|
||||
persistPrompt
|
||||
+ expandSkillMention
|
||||
launchAgent
|
||||
- navigateToSession
|
||||
+ navigateToSession
|
||||
+ subscribeToEvents
|
||||
```
|
||||
|
||||
For a state or control-flow change:
|
||||
|
||||
```diff
|
||||
on(save)
|
||||
- write content
|
||||
+ if content is unchanged
|
||||
+ return cached result
|
||||
+ write new content
|
||||
+ invalidate cache
|
||||
```
|
||||
|
||||
- Show the whole block when most of it is new, when omitted context would hide ownership or order, or when the user needs a copyable target shape:
|
||||
|
||||
```ts
|
||||
function expandSkill(command: string): string {
|
||||
const skillName = command.slice(1);
|
||||
return `use the ${skillName} skill`;
|
||||
}
|
||||
```
|
||||
|
||||
#### Guidance
|
||||
|
||||
Place each visual next to the short text it supports. Keep only the calls, files, props, states, and boundaries needed to answer the user's current question or the options to resolve the current discussion point.
|
||||
|
||||
You may use one of these, you may use several, it is unlikely you will use all of them. Use your judgement and don't overwhelm the user.
|
||||
|
||||
### Evidence
|
||||
|
||||
Concrete evidence that the change works. Show a before and after.
|
||||
|
||||
Screenshots are S-tier - when the environment is set up for it and the change is visual.
|
||||
|
||||
Execution-based evidence is A-tier. Test results, console output. Show the exact test that now fails and passes, using pseudocode.
|
||||
|
||||
### Merge Danger
|
||||
|
||||
Describe whether it's a one-way or two-way door. You can walk back through two-way doors, but not one-way doors. A PR that is cheap to roll back is lower risk. Changes that involve destructive actions or hard-to-reverse decisions are one-way doors.
|
||||
|
||||
The blast radius is the potential impact or scope of the changes introduced by this PR. Consider all possibilities. Examples are layout shift, breakages for consumers, mobile responsiveness, etc.

# Logic Prototype
|
||||
|
||||
A single, self-contained HTML file (a **shareable demo**) that lets anyone drive a state model by clicking buttons. Use this when the question is about **business logic, state transitions, or data shape**: the kind of thing that looks reasonable on paper but only feels wrong once you push it through real cases.
|
||||
|
||||
Because it's one file with nothing to install, you can hand it to a non-developer (a designer, a PM, a domain expert) and let them feel the model for themselves. So it speaks their language, not the code's.
|
||||
|
||||
## When this is the right shape
|
||||
|
||||
- "I'm not sure if this state machine handles the edge case where X then Y."
|
||||
- "Does this data model actually let me represent the case where..."
|
||||
- "I want to feel out what the API should look like before writing it."
|
||||
- Anything where someone wants to **press buttons and watch state change**.
|
||||
|
||||
If the question is "what should this look like," this is the wrong branch. Use [UI.md](UI.md).
|
||||
|
||||
## Process
|
||||
|
||||
### 1. State the question
|
||||
|
||||
Before writing code, write down what state model and what question you're prototyping. One paragraph, at the top of the demo (in a visible intro, not just a comment). A logic prototype that answers the wrong question is pure waste, so make the question explicit so it can be checked later, whether the user is watching now or returning to it AFK.
|
||||
|
||||
### 2. Isolate the logic in a portable module
|
||||
|
||||
Put the actual logic (the bit that's answering the question) in a single `<script>` block written as a small, pure module that could be lifted out and dropped into the real codebase later. The page around it is throwaway; this module isn't.
|
||||
|
||||
The right shape depends on the question:
|
||||
|
||||
- **A pure reducer**: `(state, action) => state`. Good when actions are discrete events and state is a single value.
|
||||
- **A state machine**: explicit states and transitions. Good when "which actions are even legal right now" is part of the question.
|
||||
- **A small set of pure functions** over a plain data type. Good when there's no implicit current state, just transformations.
|
||||
- **A class or module with a clear method surface** when the logic genuinely owns ongoing internal state.
|
||||
|
||||
Pick whichever shape best fits the question being asked, *not* whichever is easiest to wire to a page. Keep it pure: no DOM, no `document`, no button handlers reaching inside it. The page calls into it; nothing flows the other direction. This is what makes the prototype useful past its own lifetime: once the question's answered, the validated reducer / machine / function set lifts into the real module on its own.
|
||||
|
||||
### 3. Build the shareable HTML file
|
||||
|
||||
One file, plain HTML/CSS/JS: no framework, no bundler, no server, everything inline so it opens by double-click and survives being emailed around. Anyone should be able to run it by opening it.
|
||||
|
||||
Write it for a non-developer. Every label is in **domain language**, not code: buttons and state read like the business, not the reducer. Explain in plain words what's happening.
|
||||
|
||||
Lay it out with a clean hierarchy, top to bottom:
|
||||
|
||||
1. **Title and one-line explanation** of what this demo lets you explore (the question from step 1).
|
||||
2. **Current state**: the full relevant state, rendered as a readable panel (labelled fields, not a raw JSON dump), re-rendered after every click so the change is visible. Where it helps a non-developer follow, call out what just changed.
|
||||
3. **Free-play buttons**: one button per action, always available, so anyone can poke at the model in any order. Each click dispatches its action and re-renders the state.
|
||||
4. **Guided walkthroughs**: a set of **scenarios**, one per tab. Each tab holds a short plain-language description of the scenario (the situation it sets up and what to watch for) and underneath it, the ordered **buttons to press** for that scenario. Each step is a real button: clicking it performs that action and moves to the next step. Starting a walkthrough resets to a known initial state so the scenario runs the same way every time.
|
||||
|
||||
Choose scenarios that demonstrate the awkward cases, the ones hard to reason about on paper: the happy path, a tricky edge case, an attempt at something that should be illegal.
|
||||
|
||||
Keep it beautiful but restrained: clean typography, generous spacing, one accent colour. No animations, no gimmicks: nothing that competes with the state and the buttons.
|
||||
|
||||
### 4. Hand it over
|
||||
|
||||
Send them the file, or open it for them. They'll click through the walkthroughs and free-play whenever they get to it; the interesting moments are when they say "wait, that shouldn't be possible" or "huh, I assumed X would be different"; those are the bugs in the _idea_, which is the whole point. If they want new actions or a new scenario, add them. Prototypes evolve.
|
||||
|
||||
### 5. Capture the answer and the prototype
|
||||
|
||||
Once the prototype has answered its question, capture the answer, then capture the prototype the way the [SKILL](SKILL.md) describes. The logic-specific mapping: the validated reducer / machine / function set lifts into the real module (the decision, absorbed); the HTML shell rides along to the throwaway branch that keeps the prototype as a primary source, and being one self-contained file, it stays trivially re-runnable there.
|
||||
|
||||
## Anti-patterns
|
||||
|
||||
- **Don't add tests.** A prototype that needs tests is no longer a prototype.
|
||||
- **Don't wire it to the real database.** Use in-memory state unless the question is specifically about persistence.
|
||||
- **Don't generalise.** No "what if we wanted to support X later." The prototype answers one question.
|
||||
- **Don't blur the logic and the page together.** If the pure module references the DOM, `document`, or button handlers, it's no longer liftable. Keep the page as a thin shell over a pure module.
|
||||
- **Don't reach for a framework, bundler, or server.** One file the recipient double-clicks; a React app or a dev server defeats "shareable".
|
||||
- **Don't ship the HTML shell into production.** The page is optimised for being clicked through by hand. The logic module behind it is the bit worth keeping.

# Prototype
|
||||
|
||||
A prototype is **throwaway code that answers a question**. The question decides the shape.
|
||||
|
||||
## Pick a branch
|
||||
|
||||
Identify which question is being answered, using the user's prompt, the surrounding code, or by asking if the user is around:
|
||||
|
||||
- **"Does this logic / state model feel right?"** → [LOGIC.md](LOGIC.md). Build a single shareable HTML file (free-play buttons plus tabbed guided walkthroughs) that pushes the state machine through cases that are hard to reason about on paper, and that a non-developer can drive.

- **"What should this look like?"** → [UI.md](UI.md). Generate several radically different UI variations on a single route, switchable via a URL search param and a floating bottom bar.
|
||||
|
||||
The two branches produce very different artifacts, so getting this wrong wastes the whole prototype. If the question is genuinely ambiguous and the user isn't reachable, default to whichever branch better matches the surrounding code (a backend module → logic; a page or component → UI) and state the assumption at the top of the prototype.
|
||||
|
||||
## Rules that apply to both
|
||||
|
||||
1. **Throwaway from day one, and clearly marked as such.** Locate the prototype code close to where it will actually be used (next to the module or page it's prototyping for) so context is obvious, but name it so a casual reader can see it's a prototype, not production. For throwaway UI routes, obey whatever routing convention the project already uses; don't invent a new top-level structure.
|
||||
2. **Trivial to run.** A UI prototype starts from one command in the project's task runner: `pnpm <name>`, `python <path>`, `bun <path>`, etc. A logic demo is a single HTML file the user double-clicks. Either way, no thinking required to start it.
|
||||
3. **No persistence by default.** State lives in memory. Persistence is the thing the prototype is _checking_, not something it should depend on. If the question explicitly involves a database, hit a scratch DB or a local file with a clear "PROTOTYPE, wipe me" name.
|
||||
4. **Skip the polish.** No tests, no error handling beyond what makes the prototype _runnable_, no abstractions. The point is to learn something fast.
|
||||
5. **Surface the state.** After every action (logic) or on every variant switch (UI), print or render the full relevant state so the user can see what changed.
|
||||
6. **Capture it when done.** Fold any validated decision into the real code, then capture the prototype itself as a **primary source**: commit it to a throwaway branch, out of main, and leave a context pointer to that branch on the implementation issue. Capture the answer too (the verdict and the question it settled) in the issue or a commit. The main branch keeps only the validated decision.

# UI Prototype
|
||||
|
||||
Generate **several radically different UI variations** on a single route, switchable from a floating bottom bar. The user flips between variants in the browser, picks one (or steals bits from each), then throws the rest away.
|
||||
|
||||
If the question is about logic/state rather than what something looks like, this is the wrong branch. Use [LOGIC.md](LOGIC.md).
|
||||
|
||||
## When this is the right shape
|
||||
|
||||
- "What should this page look like?"
|
||||
- "I want to see a few options for this dashboard before committing."
|
||||
- "Try a different layout for the settings screen."
|
||||
- Any time the user would otherwise spend a day picking between three vague mockups in their head.
|
||||
|
||||
## Two sub-shapes: strongly prefer sub-shape A
|
||||
|
||||
A UI prototype is much easier to judge when it's **butting up against the rest of the app**: real header, real sidebar, real data, real density. A throwaway route on its own is a vacuum: every variant looks fine in isolation. Default to sub-shape A whenever there's a plausible existing page to host the variants. Only reach for sub-shape B if the prototype genuinely has no nearby home.
|
||||
|
||||
### Sub-shape A: adjustment to an existing page (preferred)
|
||||
|
||||
The route already exists. Variants are rendered **on the same route**, gated by a `?variant=` URL search param. The existing data fetching, params, and auth all stay. Only the rendering swaps. This is the default; pick it unless there's a specific reason not to.
|
||||
|
||||
If the prototype is for something that doesn't yet have a page but *would naturally live inside one* (a new section of the dashboard, a new card on the settings screen, a new step in an existing flow), it's still sub-shape A. Mount the variants inside the host page.
|
||||
|
||||
### Sub-shape B: a new page (last resort)
|
||||
|
||||
Only use this when the thing being prototyped genuinely has no existing page to live inside (e.g. an entirely new top-level surface, or a flow that can't be embedded anywhere sensible).
|
||||
|
||||
Create a **throwaway route** following whatever routing convention the project already uses. Don't invent a new top-level structure. Name it so it's obviously a prototype (e.g. include the word `prototype` in the path or filename). Same `?variant=` pattern.
|
||||
|
||||
Before committing to sub-shape B, sanity-check: is there really no existing page this could be embedded in? An empty route hides design problems that a populated one would expose.
|
||||
|
||||
In both sub-shapes the floating bottom bar is identical.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. State the question and pick N
|
||||
|
||||
Default to **3 variants**. More than 5 stops being radically different and starts being noise, so cap there.
|
||||
|
||||
Write down the plan in one line, in the prototype's location or a top-of-file comment:
|
||||
|
||||
> "Three variants of the settings page, switchable via `?variant=`, on the existing `/settings` route."
|
||||
|
||||
This works whether the user is here to push back or not.
|
||||
|
||||
### 2. Generate radically different variants
|
||||
|
||||
Draft each variant. Hold each one to:
|
||||
|
||||
- The page's purpose and the data it has access to.
|
||||
- The project's component library / styling system (TailwindCSS, shadcn, MUI, plain CSS, whatever).
|
||||
- A clear exported component name, e.g. `VariantA`, `VariantB`, `VariantC`.
|
||||
|
||||
Variants must be **structurally different**: different layout, different information hierarchy, different primary affordance, not just different colours. Three slightly-tweaked card grids isn't a UI prototype, it's wallpaper. If two drafts come out too similar, redo one with explicit "do not use a card grid" guidance.
|
||||
|
||||
### 3. Wire them together
|
||||
|
||||
Create a single switcher component on the route:
|
||||
|
||||
```tsx
|
||||
// pseudo-code, adapt to the project's framework
|
||||
const variant = searchParams.get('variant') ?? 'A';
|
||||
return (
|
||||
<>
|
||||
{variant === 'A' && <VariantA {...data} />}
|
||||
{variant === 'B' && <VariantB {...data} />}
|
||||
{variant === 'C' && <VariantC {...data} />}
|
||||
<PrototypeSwitcher variants={['A','B','C']} current={variant} />
|
||||
</>
|
||||
);
|
||||
```
|
||||
|
||||
For sub-shape A (existing page): keep all the existing data fetching above the switcher; only the rendered subtree changes per variant.
|
||||
|
||||
For sub-shape B (new page): the throwaway route under `/prototype/<name>` mounts the same switcher.
|
||||
|
||||
### 4. Build the floating switcher
|
||||
|
||||
A small fixed-position bar at the bottom-centre of the screen with three pieces:
|
||||
|
||||
- **Left arrow**: cycles to the previous variant (wraps around).
|
||||
- **Variant label**: shows the current variant key and, if the variant exports a name, that name too. e.g. `B (Sidebar layout)`.
|
||||
- **Right arrow**: cycles forward (wraps around).
|
||||
|
||||
Behaviour:
|
||||
|
||||
- Clicking an arrow updates the URL search param (use the framework's router, e.g. `router.replace` on Next, `navigate` on React Router, etc) so the variant is shareable and reload-stable.
|
||||
- Keyboard: `←` and `→` arrow keys also cycle. Don't intercept arrow keys when an `<input>`, `<textarea>`, or `[contenteditable]` is focused.
|
||||
- Visually distinct from the page (e.g. high-contrast pill, subtle shadow) so it's obviously not part of the design being evaluated.
|
||||
- Hidden in production builds: gate on `process.env.NODE_ENV !== 'production'` or an equivalent check, so a stray prototype merge can't ship the bar to users.
|
||||
|
||||
Put the switcher in a single shared component so both sub-shapes can reuse it. Locate it wherever shared UI lives in the project.
|
||||
|
||||
### 5. Hand it over
|
||||
|
||||
Surface the URL (and the `?variant=` keys). The user will flip through whenever they get to it. The interesting feedback is usually **"I want the header from B with the sidebar from C"**, which is the actual design they want.
|
||||
|
||||
### 6. Capture the answer and clean up
|
||||
|
||||
Once a variant has won, capture the answer (which variant and why), then capture the prototype the way the [SKILL](SKILL.md) describes. Fold the winner into the real code and move the rest onto the throwaway branch, not into main:
|
||||
|
||||
- **Sub-shape A**: fold the winner into the existing page; drop the losing variants and the switcher from main.
|
||||
- **Sub-shape B**: promote the winning variant to a real route; drop the throwaway route and the switcher from main.
|
||||
|
||||
The full set of variants is the primary source, so it lands on the throwaway branch, not the bin, since variant components and the switcher left in the main branch rot fast and confuse the next reader.
|
||||
|
||||
## Anti-patterns
|
||||
|
||||
- **Variants that differ only in colour or copy.** That's a tweak, not a prototype. Real variants disagree about structure.
|
||||
- **Sharing too much code between variants.** A shared `<Header>` is fine; a shared `<Layout>` defeats the point. Each variant should be free to throw out the layout.
|
||||
- **Wiring variants to real mutations.** Read-only prototypes are fine. If a variant needs to mutate, point it at a stub: the question is "what should this look like", not "does the backend work".
|
||||
- **Promoting the prototype directly to production.** The variant code was written under prototype constraints (no tests, minimal error handling). Rewrite it properly when you fold it in.

# Code Review Reception
|
||||
|
||||
## Overview
|
||||
|
||||
Code review requires technical evaluation, not emotional performance.
|
||||
|
||||
**Core principle:** Verify before implementing. Ask before assuming. Technical correctness over social comfort.
|
||||
|
||||
## The Response Pattern
|
||||
|
||||
```
|
||||
WHEN receiving code review feedback:
|
||||
|
||||
1. READ: Complete feedback without reacting
|
||||
2. UNDERSTAND: Restate requirement in own words (or ask)
|
||||
3. VERIFY: Check against codebase reality
|
||||
4. EVALUATE: Technically sound for THIS codebase?
|
||||
5. RESPOND: Technical acknowledgment or reasoned pushback
|
||||
6. IMPLEMENT: One item at a time, test each
|
||||
```
|
||||
|
||||
## Forbidden Responses
|
||||
|
||||
**NEVER:**
|
||||
- "You're absolutely right!" (explicit CLAUDE.md violation)
|
||||
- "Great point!" / "Excellent feedback!" (performative)
|
||||
- "Let me implement that now" (before verification)
|
||||
|
||||
**INSTEAD:**
|
||||
- Restate the technical requirement
|
||||
- Ask clarifying questions
|
||||
- Push back with technical reasoning if wrong
|
||||
- Just start working (actions > words)
|
||||
|
||||
## Handling Unclear Feedback
|
||||
|
||||
```
|
||||
IF any item is unclear:
|
||||
STOP - do not implement anything yet
|
||||
ASK for clarification on unclear items
|
||||
|
||||
WHY: Items may be related. Partial understanding = wrong implementation.
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```
|
||||
your human partner: "Fix 1-6"
|
||||
You understand 1,2,3,6. Unclear on 4,5.
|
||||
|
||||
❌ WRONG: Implement 1,2,3,6 now, ask about 4,5 later
|
||||
✅ RIGHT: "I understand items 1,2,3,6. Need clarification on 4 and 5 before proceeding."
|
||||
```
|
||||
|
||||
## Source-Specific Handling
|
||||
|
||||
### From your human partner
|
||||
- **Trusted** - implement after understanding
|
||||
- **Still ask** if scope unclear
|
||||
- **No performative agreement**
|
||||
- **Skip to action** or technical acknowledgment
|
||||
|
||||
### From External Reviewers
|
||||
```
|
||||
BEFORE implementing:
|
||||
1. Check: Technically correct for THIS codebase?
|
||||
2. Check: Breaks existing functionality?
|
||||
3. Check: Reason for current implementation?
|
||||
4. Check: Works on all platforms/versions?
|
||||
5. Check: Does reviewer understand full context?
|
||||
|
||||
IF suggestion seems wrong:
|
||||
Push back with technical reasoning
|
||||
|
||||
IF can't easily verify:
|
||||
Say so: "I can't verify this without [X]. Should I [investigate/ask/proceed]?"
|
||||
|
||||
IF conflicts with your human partner's prior decisions:
|
||||
Stop and discuss with your human partner first
|
||||
```
|
||||
|
||||
**your human partner's rule:** "External feedback - be skeptical, but check carefully"
|
||||
|
||||
## YAGNI Check for "Professional" Features
|
||||
|
||||
```
|
||||
IF reviewer suggests "implementing properly":
|
||||
grep codebase for actual usage
|
||||
|
||||
IF unused: "This endpoint isn't called. Remove it (YAGNI)?"
|
||||
IF used: Then implement properly
|
||||
```
|
||||
|
||||
**your human partner's rule:** "You and reviewer both report to me. If we don't need this feature, don't add it."
|
||||
|
||||
## Implementation Order
|
||||
|
||||
```
|
||||
FOR multi-item feedback:
|
||||
1. Clarify anything unclear FIRST
|
||||
2. Then implement in this order:
|
||||
- Blocking issues (breaks, security)
|
||||
- Simple fixes (typos, imports)
|
||||
- Complex fixes (refactoring, logic)
|
||||
3. Test each fix individually
|
||||
4. Verify no regressions
|
||||
```
|
||||
|
||||
## When To Push Back
|
||||
|
||||
Push back when:
|
||||
- Suggestion breaks existing functionality
|
||||
- Reviewer lacks full context
|
||||
- Violates YAGNI (unused feature)
|
||||
- Technically incorrect for this stack
|
||||
- Legacy/compatibility reasons exist
|
||||
- Conflicts with your human partner's architectural decisions
|
||||
|
||||
**How to push back:**
|
||||
- Use technical reasoning, not defensiveness
|
||||
- Ask specific questions
|
||||
- Reference working tests/code
|
||||
- Involve your human partner if architectural
|
||||
|
||||
**Signal if uncomfortable pushing back out loud:** "Strange things are afoot at the Circle K"
|
||||
|
||||
## Acknowledging Correct Feedback
|
||||
|
||||
When feedback IS correct:
|
||||
```
|
||||
✅ "Fixed. [Brief description of what changed]"
|
||||
✅ "Good catch - [specific issue]. Fixed in [location]."
|
||||
✅ [Just fix it and show in the code]
|
||||
|
||||
❌ "You're absolutely right!"
|
||||
❌ "Great point!"
|
||||
❌ "Thanks for catching that!"
|
||||
❌ "Thanks for [anything]"
|
||||
❌ ANY gratitude expression
|
||||
```
|
||||
|
||||
**Why no thanks:** Actions speak. Just fix it. The code itself shows you heard the feedback.
|
||||
|
||||
**If you catch yourself about to write "Thanks":** DELETE IT. State the fix instead.
|
||||
|
||||
## Gracefully Correcting Your Pushback
|
||||
|
||||
If you pushed back and were wrong:
|
||||
```
|
||||
✅ "You were right - I checked [X] and it does [Y]. Implementing now."
|
||||
✅ "Verified this and you're correct. My initial understanding was wrong because [reason]. Fixing."
|
||||
|
||||
❌ Long apology
|
||||
❌ Defending why you pushed back
|
||||
❌ Over-explaining
|
||||
```
|
||||
|
||||
State the correction factually and move on.
|
||||
|
||||
## Common Mistakes
|
||||
|
||||
| Mistake | Fix |
|
||||
|---------|-----|
|
||||
| Performative agreement | State requirement or just act |
|
||||
| Blind implementation | Verify against codebase first |
|
||||
| Batch without testing | One at a time, test each |
|
||||
| Assuming reviewer is right | Check if breaks things |
|
||||
| Avoiding pushback | Technical correctness > comfort |
|
||||
| Partial implementation | Clarify all items first |
|
||||
| Can't verify, proceed anyway | State limitation, ask for direction |
|
||||
|
||||
## Real Examples
|
||||
|
||||
**Performative Agreement (Bad):**
|
||||
```
|
||||
Reviewer: "Remove legacy code"
|
||||
❌ "You're absolutely right! Let me remove that..."
|
||||
```
|
||||
|
||||
**Technical Verification (Good):**
|
||||
```
|
||||
Reviewer: "Remove legacy code"
|
||||
✅ "Checking... build target is 10.15+, this API needs 13+. Need legacy for backward compat. Current impl has wrong bundle ID - fix it or drop pre-13 support?"
|
||||
```
|
||||
|
||||
**YAGNI (Good):**
|
||||
```
|
||||
Reviewer: "Implement proper metrics tracking with database, date filters, CSV export"
|
||||
✅ "Grepped codebase - nothing calls this endpoint. Remove it (YAGNI)? Or is there usage I'm missing?"
|
||||
```
|
||||
|
||||
**Unclear Item (Good):**
|
||||
```
|
||||
your human partner: "Fix items 1-6"
|
||||
You understand 1,2,3,6. Unclear on 4,5.
|
||||
✅ "Understand 1,2,3,6. Need clarification on 4 and 5 before implementing."
|
||||
```
|
||||
|
||||
## GitHub Thread Replies
|
||||
|
||||
When replying to inline review comments on GitHub, reply in the comment thread (`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`), not as a top-level PR comment.
|
||||
|
||||
## The Bottom Line
|
||||
|
||||
**External feedback = suggestions to evaluate, not orders to follow.**
|
||||
|
||||
Verify. Question. Then implement.
|
||||
|
||||
No performative agreement. Technical rigor always.

# Requesting Code Review
|
||||
|
||||
Dispatch a code reviewer subagent to catch issues before they cascade. The reviewer gets precisely crafted context for evaluation — never your session's history. This keeps the reviewer focused on the work product, not your thought process, and preserves your own context for continued work.
|
||||
|
||||
**Core principle:** Review early, review often.
|
||||
|
||||
## When to Request Review
|
||||
|
||||
**Mandatory:**
|
||||
- After each task in subagent-driven development
|
||||
- After completing major feature
|
||||
- Before merge to main
|
||||
|
||||
**Optional but valuable:**
|
||||
- When stuck (fresh perspective)
|
||||
- Before refactoring (baseline check)
|
||||
- After fixing complex bug
|
||||
|
||||
## How to Request
|
||||
|
||||
**1. Get git SHAs:**
|
||||
```bash
|
||||
BASE_SHA=$(git rev-parse HEAD~1) # or origin/main
|
||||
HEAD_SHA=$(git rev-parse HEAD)
|
||||
```
|
||||
|
||||
**2. Dispatch code reviewer subagent:**
|
||||
|
||||
Use Task tool with `general-purpose` type, fill template at `code-reviewer.md`
|
||||
|
||||
**Placeholders:**
|
||||
- `{DESCRIPTION}` - Brief summary of what you built
|
||||
- `{PLAN_OR_REQUIREMENTS}` - What it should do
|
||||
- `{BASE_SHA}` - Starting commit
|
||||
- `{HEAD_SHA}` - Ending commit
|
||||
|
||||
**3. Act on feedback:**
|
||||
- Fix Critical issues immediately
|
||||
- Fix Important issues before proceeding
|
||||
- Note Minor issues for later
|
||||
- Push back if reviewer is wrong (with reasoning)
|
||||
|
||||
## Example
|
||||
|
||||
```
|
||||
[Just completed Task 2: Add verification function]
|
||||
|
||||
You: Let me request code review before proceeding.

|
||||
|
||||
[Subagent returns]:
|
||||
Strengths: Clean architecture, real tests
|
||||
Issues:
|
||||
Important: Missing progress indicators
|
||||
Minor: Magic number (100) for reporting interval
|
||||
Assessment: Ready to proceed
|
||||
|
||||
You: [Fix progress indicators]
|
||||
[Continue to Task 3]
|
||||
```
|
||||
|
||||
## Integration with Workflows
|
||||
|
||||
**Subagent-Driven Development:**
|
||||
- Review after EACH task
|
||||
- Catch issues before they compound
|
||||
- Fix before moving to next task
|
||||
|
||||
**Executing Plans:**
|
||||
- Review after each task or at natural checkpoints
|
||||
- Get feedback, apply, continue
|
||||
|
||||
**Ad-Hoc Development:**
|
||||
- Review before merge
|
||||
- Review when stuck
|
||||
|
||||
## Red Flags
|
||||
|
||||
**Never:**
|
||||
- Skip review because "it's simple"
|
||||
- Ignore Critical issues
|
||||
- Proceed with unfixed Important issues
|
||||
- Argue with valid technical feedback
|
||||
|
||||
**If reviewer wrong:**
|
||||
- Push back with technical reasoning
|
||||
- Show code/tests that prove it works
|
||||
- Request clarification

## Requirements / Plan
|
||||
|
||||
{PLAN_OR_REQUIREMENTS}
|
||||
|
||||
## Git Range to Review
|
||||
|
||||
**Base:** {BASE_SHA}
|
||||
**Head:** {HEAD_SHA}
|
||||
|
||||
```bash
|
||||
git diff --stat {BASE_SHA}..{HEAD_SHA}
|
||||
git diff {BASE_SHA}..{HEAD_SHA}
|
||||
```
|
||||
|
||||
## What to Check
|
||||
|
||||
**Plan alignment:**
|
||||
- Does the implementation match the plan / requirements?
|
||||
- Are deviations justified improvements, or problematic departures?
|
||||
- Is all planned functionality present?
|
||||
|
||||
**Code quality:**
|
||||
- Clean separation of concerns?
|
||||
- Proper error handling?
|
||||
- Type safety where applicable?
|
||||
- DRY without premature abstraction?
|
||||
- Edge cases handled?
|
||||
|
||||
**Architecture:**
|
||||
- Sound design decisions?
|
||||
- Reasonable scalability and performance?
|
||||
- Security concerns?
|
||||
- Integrates cleanly with surrounding code?
|
||||
|
||||
**Testing:**
|
||||
- Tests verify real behavior, not mocks?
|
||||
- Edge cases covered?
|
||||
- Integration tests where they matter?
|
||||
- All tests passing?
|
||||
|
||||
**Production readiness:**
|
||||
- Migration strategy if schema changed?
|
||||
- Backward compatibility considered?
|
||||
- Documentation complete?
|
||||
- No obvious bugs?
|
||||
|
||||
## Calibration
|
||||
|
||||
Categorize issues by actual severity. Not everything is Critical.
|
||||
Acknowledge what was done well before listing issues — accurate praise
|
||||
helps the implementer trust the rest of the feedback.
|
||||
|
||||
If you find significant deviations from the plan, flag them specifically
|
||||
so the implementer can confirm whether the deviation was intentional.
|
||||
If you find issues with the plan itself rather than the implementation,
|
||||
say so.
|
||||
|
||||

- Give feedback on code you didn't actually read
|
||||
- Be vague ("improve error handling")
|
||||
- Avoid giving a clear verdict
|
||||
```
|
||||
|
||||
**Placeholders:**
|
||||
- `{DESCRIPTION}` — brief summary of what was built
|
||||
- `{PLAN_OR_REQUIREMENTS}` — what it should do (plan file path, task text, or requirements)
|
||||
- `{BASE_SHA}` — starting commit
|
||||
- `{HEAD_SHA}` — ending commit
|
||||
|
||||
**Reviewer returns:** Strengths, Issues (Critical / Important / Minor), Recommendations, Assessment
|
||||
|
||||
## Example Output
|
||||
|
||||
```
|
||||
### Strengths
|
||||
- Clean database schema with proper migrations (db.ts:15-42)
|
||||
- Comprehensive test coverage (18 tests, all edge cases)
|
||||
- Good error handling with fallbacks (summarizer.ts:85-92)
|
||||
|
||||
### Issues
|
||||
|
||||
#### Important
|
||||
1. **Missing help text in CLI wrapper**
|
||||
- File: index-conversations:1-31
|
||||
- Issue: No --help flag, users won't discover --concurrency
|
||||
- Fix: Add --help case with usage examples
|
||||
|
||||
2. **Date validation missing**
|
||||
- File: search.ts:25-27
|
||||
- Issue: Invalid dates silently return no results
|
||||
- Fix: Validate ISO format, throw error with example
|
||||
|
||||
#### Minor
|
||||
1. **Progress indicators**
|
||||
- File: indexer.ts:130
|
||||
- Issue: No "X of Y" counter for long operations
|
||||
- Impact: Users don't know how long to wait
|
||||
|
||||
### Recommendations
|
||||
- Add progress reporting for user experience
|
||||
- Consider config file for excluded projects (portability)
|
||||
|
||||
### Assessment
|
||||
|
||||
**Ready to merge: With fixes**
|
||||
|
||||
**Reasoning:** Core implementation is solid with good architecture and tests. Important issues (help text, date validation) are easily fixed and don't affect core functionality.

|

|

The user has asked for a **retrospective**. You are suggesting improvements to the coding agent's **environment** to improve future runs.
|
||||
|
||||
## Steps
|
||||
|
||||
1. Call the Skill tool with `writing-for-agents` for the writing style guide.
|
||||
|
||||
2. Read the primary sources for the session the user specifies. This may mean searching through session logs on this machine. If the user doesn't specify a session, default to the current one.
|
||||
|
||||
3. Look for candidates for improvement in these categories.
|
||||
|
||||
- **Navigation**: how easy was it for the agent to find the right files? Are there hidden dependencies between files? Would a **navigation pointer** make it easier? _Use when_ the session took a long time to find a piece of information.
|
||||
- **Automated checks**: are there automated checks that could catch errors the agent made? Linting, typing, tests, filesystem linters? Read the repo's own check command first (its `package.json`/build-tool `lint`/`check` scripts, its CI workflow), so a check that already exists but sits unwired or silently broken is the finding, not a reinvention. A repo with no **guardrail** (no pre-commit hook and no CI job running its lint/typecheck/test command) is itself a finding: an un-linted repo is a standing missed opportunity, not a neutral default. _Use when_ the agent made a mistake an automated check could have caught, or the repo has no guardrail at all.
|
||||
- **Coding standards**: should the **reviewer agent** be given a new rule to enforce? Should an existing rule be removed or clarified? Classify the violation first: a **mechanical** one (a fixed syntactic pattern, a banned API, an import shape, a file-location rule) gets a deterministic check, full stop: a custom rule in the repo's own linter, a new pre-commit hook, or a new CI job, whichever the repo's language and existing guardrail make cheapest. Default to building the check over writing the rule. Reserve `CODING_STANDARDS.md` for genuine **judgement calls** (cross-file consistency, "matches the surrounding style," anything no guardrail could ever substitute for). _Use when_ the reviewer agent failed to catch a mistake.
|
||||
- **Global AGENTS.md**: are there any steering instructions that should be moved to coding standards (or automated checks) instead? _Use when_ the AGENTS.md file is particularly large - in the repo OR the user's global scope.
|
||||
- **Tool economy**: did the agent make expensive tool calls that could be streamlined? Is there any custom tooling (CLI's, MCP's) that is particularly token-inefficient? _Use when_ the agent made an expensive tool call.
|
||||
- **No-ops**: look for instructions in steering files that don't modify the agent's behavior. _Use when_ the steering files are large and unwieldy.
|
||||
- **Information access**: look for opportunities to increase the agent's access to information. Teeing dev server logs, readonly access to third-party services. _Use when_ a crucial piece of information was not available to the agent.
|
||||
|
||||
4. Present these candidates to the user, in order of severity.
|
||||
|
||||
## Reference
|
||||
|
||||
### Implementation vs Review
|
||||
|
||||
Remember that all work goes through two stages: implementation and review. The implementation agent has the most **context pressure**. They are responsible for exploration, writing code, and debugging failures.
|
||||
|
||||
The review agent has the least context pressure - it receives a diff, so no exploration needed. It often does not need to write code or debug.
|
||||
|
||||
This means that the review agent should be responsible for imposing coding standards, not the implementation agent.
|
||||
|
||||
### Files
|
||||
|
||||
You have access to several files in the repo:
|
||||
|
||||
- `CLAUDE.md`/`AGENTS.md`: these files are pushed to the context window of any agent working in this repo. They should be used incredibly sparingly, usually only for **navigation pointers** to other files.
|
||||
- `CODING_STANDARDS.md`: this file is read during review, not implementation. Add **navigation pointers** to docs folders if the standards file gets more than 1,000 lines long.
|
||||
- Docs: use docs as references files, pointed to by other files. Look for existing docs before writing new ones.
|
||||
- Skills: use skills for docs (since their description goes into the agent's context window), or for user-invoked commands. Follow the advice in the `writing-for-agents` skill.

# Setup Matt Pocock's Skills
|
||||
|
||||
Scaffold the per-repo configuration that the engineering skills assume:
|
||||
|
||||
- **Issue tracker**: where issues live (GitHub by default; local markdown is also supported out of the box)
|
||||
- **Triage labels**: the strings used for the five canonical triage roles
|
||||
- **Domain docs**: where `GLOSSARY.md` and ADRs live, and the consumer rules for reading them
|
||||
|
||||
This is a prompt-driven skill, not a deterministic script. Explore, present what you found, confirm with the user, then write.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. Explore
|
||||
|
||||
Look at the current repo to understand its starting state. Read whatever exists; don't assume:
|
||||
|
||||
- `git remote -v` and `.git/config`: is this a GitHub repo? Which one?
|
||||
- `AGENTS.md` and `CLAUDE.md` at the repo root: does either exist? Is there already an `## Agent skills` section in either?
|
||||
- `GLOSSARY.md` and `GLOSSARY-MAP.md` at the repo root, and the legacy `CONTEXT.md` / `CONTEXT-MAP.md`. If a legacy file exists, offer to `git mv` it to its `GLOSSARY` name and rewrite those names in `docs/agents/domain.md`.
|
||||
- `docs/adr/` and any `src/*/docs/adr/` directories
|
||||
- `docs/agents/`: does this skill's prior output already exist?
|
||||
- `.scratch/`: a sign that a local-markdown issue tracker convention is already in use
|
||||
- Is the `triage` skill installed? (a `triage` skill folder alongside this one, or `triage` in your available skills.) This decides whether Section B runs at all.
|
||||
- Monorepo signals: a `pnpm-workspace.yaml`, a `workspaces` field in `package.json`, or a populated `packages/*` with its own `src/`. These are present only in a genuinely large multi-package repo; their absence means single-context, which is almost every repo.
|
||||
|
||||
### 2. Present findings and ask
|
||||
|
||||
Summarise what's present and what's missing. Then take the sections in order. One section, one answer, then the next.
|
||||
|
||||
Lead each section with the recommended answer so the user can accept it in a word. Give a one-line explainer only when the choice genuinely branches; skip the section entirely when exploration already settled it (Section B when `triage` isn't installed, Section C when there's no monorepo).
|
||||
|
||||
**Section A: Issue tracker.**
|
||||
|
||||
> Explainer: The "issue tracker" is where issues live for this repo. Skills like `to-tickets`, `triage`, and `to-spec` read from and write to it. They need to know whether to call `gh issue create`, write a markdown file under `.scratch/`, or follow some other workflow you describe. Pick the place you actually track work for this repo.
|
||||
|
||||
Default posture: these skills were designed for GitHub. If a `git remote` points at GitHub, propose that. If a `git remote` points at GitLab (`gitlab.com` or a self-hosted host), propose GitLab. Otherwise (or if the user prefers), offer:
|
||||
|
||||
- **GitHub**: issues live in the repo's GitHub Issues (uses the `gh` CLI)
|
||||
- **GitLab**: issues live in the repo's GitLab Issues (uses the [`glab`](https://gitlab.com/gitlab-org/cli) CLI)
|
||||
- **Local markdown**: issues live as files under `.scratch/<feature>/` in this repo (good for solo projects or repos without a remote)
|
||||
- **Other** (Jira, Linear, etc.): ask the user to describe the workflow in one paragraph; the skill will record it as freeform prose
|
||||
|
||||
Record the choice in `docs/agents/issue-tracker.md`. The GitHub and GitLab templates carry a "PRs as a request surface" flag, defaulted **off**. Leave it off and don't raise it: a user who wants external PRs in the triage queue can flip the flag in the file later.
|
||||
|
||||
A GitHub or GitLab tracker needs a reachable repo. When the user picks one and no `git remote` points at that host, get the repo URL from them and wire it up (`git init` if needed, `git remote add origin <url>`) before going further. Done when `gh repo view` / `glab repo view` prints the project from inside this directory; if it can't, stop and tell the user what's missing.
|
||||
|
||||
**Section B: Triage label vocabulary.** Skip this section entirely if the `triage` skill isn't installed (exploration told you), since an uninstalled skill needs no labels.
|
||||
|
||||
If it is installed, ask exactly one question:
|
||||
|
||||
> Do you want to keep the default triage labels? (recommended: **yes**)
|
||||
|
||||
The defaults are the five canonical roles, each label string equal to its name: `needs-triage`, `needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`. On **yes**, write them as-is. Only if the user says no, usually because their tracker already uses other names (e.g. `bug:triage` for `needs-triage`), collect the overrides so `triage` applies existing labels instead of creating duplicates.
|
||||
|
||||
**Section C: Domain docs.** Default to **single-context** (one `GLOSSARY.md` + `docs/adr/` at the repo root). This fits almost every repo; write it without asking.
|
||||
|
||||
Offer **multi-context** (a root `GLOSSARY-MAP.md` pointing to per-context `GLOSSARY.md` files) only when exploration found monorepo signals. Then confirm which layout they want.
|
||||
|
||||
### 3. Confirm and edit
|
||||
|
||||
Show the user a draft of:
|
||||
|
||||
- The `## Agent skills` block to add to whichever of `CLAUDE.md` / `AGENTS.md` is being edited (see step 4 for selection rules)
|
||||
- The contents of `docs/agents/issue-tracker.md`, `docs/agents/domain.md`, and `docs/agents/triage-labels.md` (the last only when `triage` is installed)
|
||||
|
||||
Let them edit before writing.
|
||||
|
||||
### 4. Write
|
||||
|
||||
**Pick the file to edit:**
|
||||
|
||||
- If `CLAUDE.md` exists, edit it.
|
||||
- Else if `AGENTS.md` exists, edit it.
|
||||
- If neither exists, ask the user which one to create; don't pick for them.
|
||||
|
||||
Never create `AGENTS.md` when `CLAUDE.md` already exists (or vice versa); always edit the one that's already there.
|
||||
|
||||
If an `## Agent skills` block already exists in the chosen file, update its contents in-place rather than appending a duplicate. Don't overwrite user edits to the surrounding sections.
|
||||
|
||||
The block:
|
||||
|
||||
```markdown
|
||||
## Agent skills
|
||||
|
||||
### Issue tracker
|
||||
|
||||
[one-line summary of where issues are tracked]. See `docs/agents/issue-tracker.md`.
|
||||
|
||||
### Triage labels
|
||||
|
||||
[one-line summary of the label vocabulary]. See `docs/agents/triage-labels.md`.
|
||||
|
||||
### Domain docs
|
||||
|
||||
[one-line summary of layout: "single-context" or "multi-context"]. See `docs/agents/domain.md`.
|
||||
```
|
||||
|
||||
Include the `### Triage labels` sub-block, and write `docs/agents/triage-labels.md`, only when `triage` is installed and Section B ran. When it isn't, both are omitted.
|
||||
|
||||
When Section B ran on GitHub or GitLab, create each configured label the tracker lacks (`gh label create` / `glab label create`).
|
||||
|
||||
Then write the docs files using the seed templates in this skill folder as a starting point:
|
||||
|
||||
- [issue-tracker-github.md](./issue-tracker-github.md): GitHub issue tracker
|
||||
- [issue-tracker-gitlab.md](./issue-tracker-gitlab.md): GitLab issue tracker
|
||||
- [issue-tracker-local.md](./issue-tracker-local.md): local-markdown issue tracker
|
||||
- [triage-labels.md](./triage-labels.md): label mapping (only if `triage` is installed)
|
||||
- [domain.md](./domain.md): domain doc consumer rules + layout
|
||||
|
||||
For "other" issue trackers, write `docs/agents/issue-tracker.md` from scratch using the user's description.
|
||||
|
||||
### 5. Done
|
||||
|
||||
Tell the user the setup is complete and which engineering skills will now read from these files. Mention they can edit `docs/agents/*.md` directly later; re-running this skill is only necessary if they want to switch issue trackers or restart from scratch.

# Domain Docs
|
||||
|
||||
How the engineering skills should consume this repo's domain documentation when exploring the codebase.
|
||||
|
||||
## Before exploring, read these
|
||||
|
||||
- **`GLOSSARY.md`** at the repo root, or
|
||||
- **`GLOSSARY-MAP.md`** at the repo root if it exists: it points at one `GLOSSARY.md` per context. Read each one relevant to the topic.
|
||||
- **`docs/adr/`**: read ADRs that touch the area you're about to work in. In multi-context repos, also check `src/<context>/docs/adr/` for context-scoped decisions.
|
||||
|
||||
If any of these files don't exist, **proceed silently**. Don't flag their absence; don't suggest creating them upfront. The `/domain-modeling` skill (reached via `/grill-with-docs` and `/improve-codebase-architecture`) creates them lazily when terms or decisions actually get resolved.
|
||||
|
||||
## File structure
|
||||
|
||||
Single-context repo (most repos):
|
||||
|
||||
```
|
||||
/
|
||||
├── GLOSSARY.md
|
||||
├── docs/adr/
|
||||
│ ├── 0001-event-sourced-orders.md
|
||||
│ └── 0002-postgres-for-write-model.md
|
||||
└── src/
|
||||
```
|
||||
|
||||
Multi-context repo (presence of `GLOSSARY-MAP.md` at the root):
|
||||
|
||||
```
|
||||
/
|
||||
├── GLOSSARY-MAP.md
|
||||
├── docs/adr/ ← system-wide decisions
|
||||
└── src/
|
||||
├── ordering/
|
||||
│ ├── GLOSSARY.md
|
||||
│ └── docs/adr/ ← context-specific decisions
|
||||
└── billing/
|
||||
├── GLOSSARY.md
|
||||
└── docs/adr/
|
||||
```
|
||||
|
||||
## Use the glossary's vocabulary
|
||||
|
||||
When your output names a domain concept (in an issue title, a refactor proposal, a hypothesis, a test name), use the term as defined in `GLOSSARY.md`. Don't drift to synonyms the glossary explicitly avoids.
|
||||
|
||||
If the concept you need isn't in the glossary yet, that's a signal: either you're inventing language the project doesn't use (reconsider) or there's a real gap (note it for `/domain-modeling`).
|
||||
|
||||
## Flag ADR conflicts
|
||||
|
||||
If your output contradicts an existing ADR, surface it explicitly rather than silently overriding:

||||

# Issue tracker: GitHub
|
||||
|
||||
Issues and specs for this repo live as GitHub issues. Use the `gh` CLI for all operations.
|
||||
|
||||
## Conventions
|
||||
|
||||
- **Create an issue**: `gh issue create --title "..." --body "..."`. Use a heredoc for multi-line bodies.
|
||||
- **Read an issue**: `gh issue view <number> --json number,title,body,labels,comments`.
|
||||
- **List issues**: `gh issue list --state open --json number,title,body,labels,comments --jq '[.[] | {number, title, body, labels: [.labels[].name], comments: [.comments[].body]}]'` with appropriate `--label` and `--state` filters.
|
||||
- **Make an issue a sub-issue of a parent**: `gh issue create --parent <parent> ...`, or `gh issue edit <parent> --add-sub-issue <child>` afterwards (`gh` 2.94+). Older `gh`: `gh api --method POST repos/<owner>/<repo>/issues/<parent>/sub_issues -F sub_issue_id=<child-db-id>` (database id, as in **Blocking** below). Without sub-issues, put `Part of #<parent>` at the top of the child body.
|
||||
- **Blocking**: GitHub's **native issue dependencies**, the canonical, UI-visible representation. Add an edge with `gh issue create --blocked-by <n>,<n> ...` or `gh issue edit <child> --add-blocked-by <blocker>` (`gh` 2.94+). Older `gh`: `gh api --method POST repos/<owner>/<repo>/issues/<child>/dependencies/blocked_by -F issue_id=<blocker-db-id>`, where `<blocker-db-id>` is the blocker's numeric **database id** (`gh api repos/<owner>/<repo>/issues/<n> --jq .id`, _not_ the `#number` or `node_id`). Where dependencies aren't available, fall back to a `Blocked by: #<n>, #<n>` line at the top of the child body. A ticket is unblocked when every blocker is closed.
|
||||
- **Count open blockers**: `gh api repos/<owner>/<repo>/issues/<n> --jq .issue_dependencies_summary.blocked_by` (open blockers only; 0 means startable). `gh issue view <n> --json blockedBy` also lists closed blockers, so filter it: `--jq '[.blockedBy.nodes[] | select(.state == "OPEN")] | length'`.
|
||||
- **Comment on an issue**: `gh issue comment <number> --body "..."`
|
||||
- **Apply / remove labels**: `gh issue edit <number> --add-label "..."` / `--remove-label "..."`
|
||||
- **Close**: post the explanation with `gh issue comment <number> --body "..."`, then `gh issue close <number>`. On an already-closed issue, `gh issue close --comment` drops the comment and still exits 0.
|
||||
|
||||
Infer the repo from `git remote -v`; `gh` does this automatically when run inside a clone.
|
||||
|
||||
File issues only into the user's own repo. Never file into `mattpocock/skills` (the repo these skills come from) unless the user owns it. In a fork, `gh` can default to the upstream parent, so before the first `gh issue create` of a session, check the target with `gh repo view --json nameWithOwner` and confirm it with the user if it is not their repo.
|
||||
|
||||
## Pull requests as a triage surface
|
||||
|
||||
**PRs as a request surface: no.** _(Set to `yes` if this repo treats external PRs as feature requests; `/triage` reads this flag.)_
|
||||
|
||||
When set to `yes`, PRs run through the same labels and states as issues, using the `gh pr` equivalents:
|
||||
|
||||
- **Read a PR**: `gh pr view <number>`, then `gh pr view <number> --comments` (off a TTY, `--comments` prints only the comments, not the body), and `gh pr diff <number>` for the diff.
|
||||
- **List external PRs for triage**: `gh api --paginate 'repos/{owner}/{repo}/pulls?state=open' --jq '.[] | select(.author_association | IN("OWNER","MEMBER","COLLABORATOR") | not) | {number, title, author: .user.login, author_association, labels: [.labels[].name]}'`.
|
||||
- **Comment / label / close**: `gh pr comment`, `gh pr edit --add-label`/`--remove-label`, `gh pr close`.
|
||||
|
||||
GitHub shares one number space across issues and PRs, so a bare `#42` may be either: resolve with `gh pr view 42` and fall back to `gh issue view 42`.
|
||||
|
||||
## When a skill says "publish to the issue tracker"
|
||||
|
||||
Create a GitHub issue.
|
||||
|
||||
## When a skill says "fetch the relevant ticket"
|
||||
|
||||
Read it as in **Read an issue** above.
|
||||
|
||||
## Wayfinding operations
|
||||
|
||||
Used by `/wayfinder`. The **map** is a single issue with **child** issues as tickets.
|
||||
|
||||
- **Map**: a single issue labelled `wayfinder:map`, holding the Notes / Decisions-so-far / Fog body. `gh issue create --label wayfinder:map`.
|
||||
- **Child ticket**: an issue linked to the map as a GitHub sub-issue (see **Make an issue a sub-issue of a parent**). Where sub-issues aren't enabled, add the child to a task list in the map body and put `Part of #<map>` at the top of the child body. Labels: `wayfinder:<type>` (`research`/`prototype`/`grilling`/`task`). Once claimed, the ticket is assigned to the driving dev.
|
||||
- **Blocking**: see **Blocking** under Conventions.
|
||||
- **Frontier query**: list the map's open children (`gh issue list --state open`, scoped to the map's sub-issues / task list), drop any with an open blocker (see **Count open blockers**, or an open issue in the `Blocked by` line) or an assignee; first in map order wins.
|
||||
- **Claim**: `gh issue edit <n> --add-assignee @me`, the session's first write.
|
||||
- **Resolve**: `gh issue comment <n> --body "<answer>"`, then `gh issue close <n>`, then append a context pointer (gist + link) to the map's Decisions-so-far.

# Issue tracker: GitLab
|
||||
|
||||
Issues and specs for this repo live as GitLab issues. Use the [`glab`](https://gitlab.com/gitlab-org/cli) CLI for all operations.
|
||||
|
||||
## Conventions
|
||||
|
||||
- **Create an issue**: `glab issue create --title "..." --description "..."`. Use a heredoc for multi-line descriptions. Pass `--description -` to open an editor.
|
||||
- **Read an issue**: `glab issue view <number> --comments`. Use `-F json` for machine-readable output.
|
||||
- **List issues**: `glab issue list -O json` with appropriate `--label` filters.
|
||||
- **Comment on an issue**: `glab issue note <number> --message "..."`. GitLab calls comments "notes".
|
||||
- **Apply / remove labels**: `glab issue update <number> --label "..."` / `--unlabel "..."`. Multiple labels can be comma-separated or by repeating the flag.
|
||||
- **Close**: `glab issue close <number>`. `glab issue close` does not accept a closing comment, so post the explanation first with `glab issue note <number> --message "..."`, then close.
|
||||
- **Merge requests**: GitLab calls PRs "merge requests". Use `glab mr create`, `glab mr view`, `glab mr note`, etc., the same shape as `gh pr ...` with `mr` in place of `pr` and `note`/`--message` in place of `comment`/`--body`.
|
||||
|
||||
Infer the repo from `git remote -v`; `glab` does this automatically when run inside a clone.
|
||||
|
||||
## Merge requests as a triage surface
|
||||
|
||||
**MRs as a request surface: no.** _(Set to `yes` if this repo treats external merge requests as feature requests; `/triage` reads this flag.)_
|
||||
|
||||
When set to `yes`, MRs run through the same labels and states as issues, using the `glab mr` equivalents:
|
||||
|
||||
- **Read an MR**: `glab mr view <number> --comments` and `glab mr diff <number>` for the diff.
|
||||
- **List external MRs for triage**: `glab mr list -O json`, then keep only MRs whose author is not a project member/owner (a contributor's MR, not a maintainer's in-flight work).
|
||||
- **Comment / label / close**: `glab mr note`, `glab mr update --label`/`--unlabel`, `glab mr close`.
|
||||
|
||||
Unlike GitHub, GitLab numbers issues and MRs separately, so `#42` is unambiguous once you know which surface the maintainer means.
|
||||
|
||||
## When a skill says "publish to the issue tracker"
|
||||
|
||||
Create a GitLab issue.
|
||||
|
||||
## When a skill says "fetch the relevant ticket"
|
||||
|
||||
Run `glab issue view <number> --comments`.
|
||||
|
||||
## Wayfinding operations
|
||||
|
||||
Used by `/wayfinder`. The **map** is a single issue with **child** issues as tickets.
|
||||
|
||||
- **Map**: a single issue labelled `wayfinder:map`, holding the Notes / Decisions-so-far / Fog body. `glab issue create --label wayfinder:map`. (On GitLab tiers with native epics, an epic may hold the map instead; a labelled issue works everywhere.)
|
||||
- **Child ticket**: an issue carrying `Part of #<map>` at the top of its description, linked to the map (`glab issue create --linked-issues <map> --link-type relates_to`), and labels `wayfinder:<type>` (`research`/`prototype`/`grilling`/`task`). Once claimed, the ticket is assigned to the driving dev.
|
||||
- **Blocking**: GitLab's **native blocking link**, the canonical, UI-visible representation. Add it with the `/blocked_by #<n>` quick action, posted as a note (`glab issue note <child> --message "/blocked_by #<blocker>"`). Native blocking links are a Premium/Ultimate feature; on the free tier (or where unavailable) fall back to a `Blocked by: #<n>, #<n>` line at the top of the description. A ticket is unblocked when every blocker is closed.
|
||||
- **Frontier query**: list the map's children with `glab api projects/:id/issues/<map>/links`, keeping open issues that carry a `wayfinder:<type>` label; drop any with an open blocker: a native `blocked_by` link to an open issue (`glab api projects/:id/issues/<child-iid>/links`), or an open issue in the `Blocked by` line, or an assignee; first in map order wins.
|
||||
- **Claim**: `glab issue update <n> --assignee @me`, the session's first write.
|
||||
- **Resolve**: `glab issue note <n> --message "<answer>"`, then `glab issue close <n>`, then append a context pointer (gist + link) to the map's Decisions-so-far.

# Issue tracker: Local Markdown
|
||||
|
||||
Issues and specs for this repo live as markdown files in `.scratch/`.
|
||||
|
||||
## Conventions
|
||||
|
||||
- One feature per directory: `.scratch/<feature-slug>/`
|
||||
- The spec is `.scratch/<feature-slug>/spec.md`
|
||||
- Implementation issues are one file per ticket at `.scratch/<feature-slug>/issues/<NN>-<slug>.md`, numbered from `01`, never a single combined tickets file
|
||||
- Triage state is recorded as a `Status:` line near the top of each issue file (see `triage-labels.md` for the role strings)
|
||||
- Comments and conversation history append to the bottom of the file under a `## Comments` heading
|
||||
|
||||
## When a skill says "publish to the issue tracker"
|
||||
|
||||
Create a new file under `.scratch/<feature-slug>/` (creating the directory if needed).
|
||||
|
||||
## When a skill says "fetch the relevant ticket"
|
||||
|
||||
Read the file at the referenced path. The user will normally pass the path or the issue number directly.
|
||||
|
||||
## Wayfinding operations
|
||||
|
||||
Used by `/wayfinder`. The **map** is a file with one **child** file per ticket.

- **Map**: `.scratch/<effort>/map.md` (the Notes / Decisions-so-far / Fog body).
|
||||
- **Child ticket**: `.scratch/<effort>/issues/NN-<slug>.md`, numbered from `01`, with the question in the body. A `Type:` line records the ticket type (`research`/`prototype`/`grilling`/`task`); a `Status:` line records `claimed`/`resolved`.
|
||||
- **Blocking**: a `Blocked by: NN, NN` line near the top. A ticket is unblocked when every file it lists is `resolved`.
|
||||
- **Frontier**: scan `.scratch/<effort>/issues/` for files that are open, unblocked, and unclaimed; first by number wins.
|
||||
- **Claim**: set `Status: claimed` and save before any work.
|
||||
- **Resolve**: append the answer under an `## Answer` heading, set `Status: resolved`, then append a context pointer (gist + link) to the map's Decisions-so-far in `map.md`.

# Triage Labels
|
||||
|
||||
The skills speak in terms of five canonical triage roles. This file maps those roles to the actual label strings used in this repo's issue tracker.
|
||||
|
||||
| Label in mattpocock/skills | Label in our tracker | Meaning |
|
||||
| -------------------------- | -------------------- | ---------------------------------------- |

| `needs-triage` | `needs-triage` | Maintainer needs to evaluate this issue |
|
||||
| `needs-info` | `needs-info` | Waiting on reporter for more information |
|
||||
| `ready-for-agent` | `ready-for-agent` | Fully specified, ready for an AFK agent |
|

| `ready-for-human` | `ready-for-human` | Requires human implementation |
|
||||
| `wontfix` | `wontfix` | Will not be actioned |
|
||||
|
||||
When a skill mentions a role (e.g. "apply the AFK-ready triage label"), use the corresponding label string from this table.

description: Use when executing implementation plans with independent tasks in the current session

|

# Subagent-Driven Development
|
||||
|
||||
Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.
|
||||
|
||||
**Why subagents:** You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
|
||||
|
||||
**Core principle:** Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration
|
||||
|
||||
**Continuous execution:** Do not pause to check in with your human partner between tasks. Execute all tasks from the plan without stopping. The only reasons to stop are: BLOCKED status you cannot resolve, ambiguity that genuinely prevents progress, or all tasks complete. "Should I continue?" prompts and progress summaries waste their time — they asked you to execute the plan, so execute it.
|
||||
|
||||
## When to Use
|
||||
|
||||
```dot
|
||||
digraph when_to_use {
|
||||
"Have implementation plan?" [shape=diamond];
|
||||
"Tasks mostly independent?" [shape=diamond];
|
||||
"Stay in this session?" [shape=diamond];
|
||||
"subagent-driven-development" [shape=box];
|
||||
"executing-plans" [shape=box];
|
||||
"Manual execution or brainstorm first" [shape=box];
|
||||
|
||||
"Have implementation plan?" -> "Tasks mostly independent?" [label="yes"];
|
||||
"Have implementation plan?" -> "Manual execution or brainstorm first" [label="no"];
|
||||
"Tasks mostly independent?" -> "Stay in this session?" [label="yes"];
|
||||
"Tasks mostly independent?" -> "Manual execution or brainstorm first" [label="no - tightly coupled"];
|
||||
"Stay in this session?" -> "subagent-driven-development" [label="yes"];
|
||||
"Stay in this session?" -> "executing-plans" [label="no - parallel session"];
|
||||
}
|
||||
```
|
||||
|
||||
**vs. Executing Plans (parallel session):**
|
||||
- Same session (no context switch)
|
||||
- Fresh subagent per task (no context pollution)
|
||||
- Two-stage review after each task: spec compliance first, then code quality
|
||||
- Faster iteration (no human-in-loop between tasks)

}
|

```
|
||||
|
||||
## Model Selection
|
||||
|
||||
Use the least powerful model that can handle each role to conserve cost and increase speed.
|
||||
|
||||
**Mechanical implementation tasks** (isolated functions, clear specs, 1-2 files): use a fast, cheap model. Most implementation tasks are mechanical when the plan is well-specified.
|
||||
|
||||
**Integration and judgment tasks** (multi-file coordination, pattern matching, debugging): use a standard model.
|
||||
|
||||
**Architecture, design, and review tasks**: use the most capable available model.
|
||||
|
||||
**Task complexity signals:**
|
||||
- Touches 1-2 files with a complete spec → cheap model
|
||||
- Touches multiple files with integration concerns → standard model
|
||||
- Requires design judgment or broad codebase understanding → most capable model
|
||||
|
||||
## Handling Implementer Status
|
||||
|
||||
Implementer subagents report one of four statuses. Handle each appropriately:
|
||||
|
||||
**DONE:** Proceed to spec compliance review.
|
||||
|
||||
**DONE_WITH_CONCERNS:** The implementer completed the work but flagged doubts. Read the concerns before proceeding. If the concerns are about correctness or scope, address them before review. If they're observations (e.g., "this file is getting large"), note them and proceed to review.
|
||||
|
||||
**NEEDS_CONTEXT:** The implementer needs information that wasn't provided. Provide the missing context and re-dispatch.
|
||||
|
||||
**BLOCKED:** The implementer cannot complete the task. Assess the blocker:
|
||||
1. If it's a context problem, provide more context and re-dispatch with the same model
|
||||
2. If the task requires more reasoning, re-dispatch with a more capable model
|
||||
3. If the task is too large, break it into smaller pieces
|
||||
4. If the plan itself is wrong, escalate to the human
|
||||
|
||||
**Never** ignore an escalation or force the same model to retry without changes. If the implementer said it's stuck, something needs to change.
|
||||
|
||||
## Prompt Templates
|
||||
|
||||
- `./implementer-prompt.md` - Dispatch implementer subagent
|
||||
- `./spec-reviewer-prompt.md` - Dispatch spec compliance reviewer subagent
|
||||
- `./code-quality-reviewer-prompt.md` - Dispatch code quality reviewer subagent
|
||||
|
||||
## Example Workflow
|
||||
|
||||
```
|
||||
You: I'm using Subagent-Driven Development to execute this plan.
|
||||
|
||||
[Read plan file once: docs/superpowers/plans/feature-plan.md]
|
||||
[Extract all 5 tasks with full text and context]
|
||||
[Create TodoWrite with all tasks]
|
||||
|
||||
Task 1: Hook installation script
|
||||
|
||||
[Get Task 1 text and context (already extracted)]
|
||||
[Dispatch implementation subagent with full task text + context]
|
||||
|
||||
Implementer: "Before I begin - should the hook be installed at user or system level?"
|
||||
|
||||
You: "User level (~/.config/superpowers/hooks/)"
|
||||
|
||||
Implementer: "Got it. Implementing now..."
|
||||
[Later] Implementer:
|
||||
- Implemented install-hook command
|
||||
- Added tests, 5/5 passing
|
||||
- Self-review: Found I missed --force flag, added it
|
||||
- Committed
|
||||
|
||||
[Dispatch spec compliance reviewer]
|
||||
Spec reviewer: ✅ Spec compliant - all requirements met, nothing extra
|
||||
|
||||
[Get git SHAs, dispatch code quality reviewer]
|
||||
Code reviewer: Strengths: Good test coverage, clean. Issues: None. Approved.
|
||||
|
||||
[Mark Task 1 complete]
|
||||
|
||||
Task 2: Recovery modes
|
||||
|
||||
[Get Task 2 text and context (already extracted)]
|
||||
[Dispatch implementation subagent with full task text + context]
|
||||
|
||||
Implementer: [No questions, proceeds]
|
||||
Implementer:
|
||||
- Added verify/repair modes
|
||||
- 8/8 tests passing
|
||||
- Self-review: All good
|
||||
- Committed
|
||||
|
||||
[Dispatch spec compliance reviewer]
|
||||
Spec reviewer: ❌ Issues:
|
||||
- Missing: Progress reporting (spec says "report every 100 items")
|
||||
- Extra: Added --json flag (not requested)
|
||||
|
||||
[Implementer fixes issues]
|
||||
Implementer: Removed --json flag, added progress reporting
|
||||
|
||||
[Spec reviewer reviews again]
|
||||
Spec reviewer: ✅ Spec compliant now
|
||||
|
||||
[Dispatch code quality reviewer]
|
||||
Code reviewer: Strengths: Solid. Issues (Important): Magic number (100)
|
||||
|
||||
[Implementer fixes]
|
||||
Implementer: Extracted PROGRESS_INTERVAL constant
|
||||
|
||||
[Code reviewer reviews again]
|
||||
Code reviewer: ✅ Approved
|
||||
|
||||
[Mark Task 2 complete]
|
||||
|
||||
...
|
||||
|
||||
[After all tasks]
|
||||
[Dispatch final code-reviewer]
|
||||
Final reviewer: All requirements met, ready to merge
|
||||
|
||||
Done!
|
||||
```
|
||||
|
||||
## Advantages
|
||||
|
||||
**vs. Manual execution:**
|
||||
- Subagents follow TDD naturally
|
||||
- Fresh context per task (no confusion)
|
||||
- Parallel-safe (subagents don't interfere)
|
||||
- Subagent can ask questions (before AND during work)
|
||||
|
||||
**vs. Executing Plans:**
|
||||
- Same session (no handoff)
|
||||
- Continuous progress (no waiting)
|
||||
- Review checkpoints automatic
|
||||
|
||||
**Efficiency gains:**
|
||||
- No file reading overhead (controller provides full text)
|
||||
- Controller curates exactly what context is needed
|
||||
- Subagent gets complete information upfront
|
||||
- Questions surfaced before work begins (not after)
|
||||
|
||||
**Quality gates:**
|
||||
- Self-review catches issues before handoff
|
||||
- Two-stage review: spec compliance, then code quality
|
||||
- Review loops ensure fixes actually work
|
||||
- Spec compliance prevents over/under-building
|
||||
- Code quality ensures implementation is well-built
|
||||
|
||||
**Cost:**
|
||||
- More subagent invocations (implementer + 2 reviewers per task)
|
||||
- Controller does more prep work (extracting all tasks upfront)
|
||||
- Review loops add iterations
|
||||
- But catches issues early (cheaper than debugging later)
|
||||
|
||||
## Red Flags
|
||||
|
||||
**Never:**
|
||||
- Start implementation on main/master branch without explicit user consent
|
||||
- Skip reviews (spec compliance OR code quality)
|
||||
- Proceed with unfixed issues
|
||||
- Dispatch multiple implementation subagents in parallel (conflicts)
|
||||
- Make subagent read plan file (provide full text instead)
|
||||
- Skip scene-setting context (subagent needs to understand where task fits)
|
||||
- Ignore subagent questions (answer before letting them proceed)
|
||||
- Accept "close enough" on spec compliance (spec reviewer found issues = not done)
|
||||
- Skip review loops (reviewer found issues = implementer fixes = review again)
|
||||
- Let implementer self-review replace actual review (both are needed)
|
||||
- **Start code quality review before spec compliance is ✅** (wrong order)
|
||||
- Move to next task while either review has open issues
|
||||
|
||||
**If subagent asks questions:**
|
||||
- Answer clearly and completely
|
||||
- Provide additional context if needed
|
||||
- Don't rush them into implementation
|
||||
|
||||
**If reviewer finds issues:**
|
||||
- Implementer (same subagent) fixes them
|
||||
- Reviewer reviews again
|
||||
- Repeat until approved
|
||||
- Don't skip the re-review
|
||||
|
||||
**If subagent fails task:**
|
||||
- Dispatch fix subagent with specific instructions
|
||||
- Don't try to fix manually (context pollution)
|
||||
|
||||
## Integration
|
||||
|
||||
**Required workflow skills:**
|
||||
- **superpowers:using-git-worktrees** - Ensures isolated workspace (creates one or verifies existing)
|
||||
- **superpowers:writing-plans** - Creates the plan this skill executes
|
||||
- **superpowers:requesting-code-review** - Code review template for reviewer subagents
|
||||
- **superpowers:finishing-a-development-branch** - Complete development after all tasks
|
||||
|
||||
**Subagents should use:**
|
||||
- **superpowers:test-driven-development** - Subagents follow TDD for each task
|
||||
|
||||
**Alternative workflow:**
|
||||
- **superpowers:executing-plans** - Use for parallel session instead of same-session execution

# Implementer Subagent Prompt Template
|
||||
|
||||
Use this template when dispatching an implementer subagent.
|
||||
|
||||
```
|
||||
Task tool (general-purpose):
|
||||
description: "Implement Task N: [task name]"
|
||||
prompt: |
|
||||
You are implementing Task N: [task name]
|
||||
|
||||
## Task Description
|
||||
|
||||
[FULL TEXT of task from plan - paste it here, don't make subagent read file]
|
||||
|
||||
## Context
|
||||
|
||||
[Scene-setting: where this fits, dependencies, architectural context]
|
||||
|
||||
## Before You Begin
|
||||
|
||||
If you have questions about:
|
||||
- The requirements or acceptance criteria
|
||||
- The approach or implementation strategy
|
||||
- Dependencies or assumptions
|
||||
- Anything unclear in the task description
|
||||
|
||||
**Ask them now.** Raise any concerns before starting work.
|
||||
|
||||
## Your Job
|
||||
|
||||
Once you're clear on requirements:
|
||||
1. Implement exactly what the task specifies
|
||||
2. Write tests (following TDD if task says to)
|
||||
3. Verify implementation works
|
||||
4. Commit your work
|
||||
5. Self-review (see below)
|
||||
6. Report back
|
||||
|
||||
Work from: [directory]
|
||||
|
||||
**While you work:** If you encounter something unexpected or unclear, **ask questions**.
|
||||
It's always OK to pause and clarify. Don't guess or make assumptions.
|
||||
|
||||
## Code Organization
|
||||
|
||||
You reason best about code you can hold in context at once, and your edits are more
|
||||
reliable when files are focused. Keep this in mind:
|
||||
- Follow the file structure defined in the plan
|
||||
- Each file should have one clear responsibility with a well-defined interface
|
||||
- If a file you're creating is growing beyond the plan's intent, stop and report
|
||||
it as DONE_WITH_CONCERNS — don't split files on your own without plan guidance
|
||||
- If an existing file you're modifying is already large or tangled, work carefully
|
||||
and note it as a concern in your report
|
||||
- In existing codebases, follow established patterns. Improve code you're touching
|
||||
the way a good developer would, but don't restructure things outside your task.
|
||||
|
||||
## When You're in Over Your Head
|
||||
|
||||
It is always OK to stop and say "this is too hard for me." Bad work is worse than
|
||||
no work. You will not be penalized for escalating.
|
||||
|
||||
**STOP and escalate when:**
|
||||
- The task requires architectural decisions with multiple valid approaches
|
||||
- You need to understand code beyond what was provided and can't find clarity
|
||||
- You feel uncertain about whether your approach is correct
|
||||
- The task involves restructuring existing code in ways the plan didn't anticipate
|
||||
- You've been reading file after file trying to understand the system without progress
|
||||
|
||||
**How to escalate:** Report back with status BLOCKED or NEEDS_CONTEXT. Describe
|
||||
specifically what you're stuck on, what you've tried, and what kind of help you need.
|
||||
The controller can provide more context, re-dispatch with a more capable model,
|
||||
or break the task into smaller pieces.
|
||||
|
||||
## Before Reporting Back: Self-Review
|
||||
|
||||
Review your work with fresh eyes. Ask yourself:
|
||||
|
||||
**Completeness:**
|
||||
- Did I fully implement everything in the spec?
|
||||
- Did I miss any requirements?
|
||||
- Are there edge cases I didn't handle?
|
||||
|
||||
**Quality:**
|
||||
- Is this my best work?
|
||||
- Are names clear and accurate (match what things do, not how they work)?
|
||||
- Is the code clean and maintainable?
|
||||
|
||||
**Discipline:**
|
||||
- Did I avoid overbuilding (YAGNI)?
|
||||
- Did I only build what was requested?
|
||||
- Did I follow existing patterns in the codebase?
|
||||
|
||||
**Testing:**
|
||||
- Do tests actually verify behavior (not just mock behavior)?
|
||||
- Did I follow TDD if required?
|
||||
- Are tests comprehensive?
|
||||
|
||||
If you find issues during self-review, fix them now before reporting.
|
||||
|
||||
## Report Format
|
||||
|
||||
When done, report:
|
||||
- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
|
||||
- What you implemented (or what you attempted, if blocked)
|
||||
- What you tested and test results
|
||||
- Files changed
|
||||
- Self-review findings (if any)
|
||||
- Any issues or concerns
|
||||
|
||||
Use DONE_WITH_CONCERNS if you completed the work but have doubts about correctness.
|
||||
Use BLOCKED if you cannot complete the task. Use NEEDS_CONTEXT if you need
|
||||
information that wasn't provided. Never silently produce work you're unsure about.

# Spec Compliance Reviewer Prompt Template
|
||||
|
||||
Use this template when dispatching a spec compliance reviewer subagent.
|
||||
|
||||
**Purpose:** Verify implementer built what was requested (nothing more, nothing less)
|
||||
|
||||
```
|
||||
Task tool (general-purpose):
|
||||
description: "Review spec compliance for Task N"

You are reviewing whether an implementation matches its specification.

## What Was Requested

## What Implementer Claims They Built
|
||||
|
||||
[From implementer's report]
|
||||
|
||||
## CRITICAL: Do Not Trust the Report
|
||||
|
||||
The implementer finished suspiciously quickly. Their report may be incomplete,
|
||||
inaccurate, or optimistic. You MUST verify everything independently.
|
||||
|
||||
**DO NOT:**
|
||||
- Take their word for what they implemented
|
||||
- Trust their claims about completeness
|
||||
- Accept their interpretation of requirements
|
||||
|
||||
**DO:**
|
||||
- Read the actual code they wrote
|
||||
- Compare actual implementation to requirements line by line
|
||||
- Check for missing pieces they claimed to implement
|
||||
- Look for extra features they didn't mention
|
||||
|
||||
## Your Job
|
||||
|
||||
Read the implementation code and verify:
|
||||
|
||||
**Missing requirements:**
|
||||
- Did they implement everything that was requested?
|
||||
- Are there requirements they skipped or missed?
|
||||
- Did they claim something works but didn't actually implement it?
|
||||
|
||||
**Extra/unneeded work:**
|
||||
- Did they build things that weren't requested?
|
||||
- Did they over-engineer or add unnecessary features?
|
||||
- Did they add "nice to haves" that weren't in spec?
|
||||
|
||||
**Misunderstandings:**
|
||||
- Did they interpret requirements differently than intended?
|
||||
- Did they solve the wrong problem?
|
||||
- Did they implement the right feature but wrong way?
|
||||
|
||||
**Verify by reading code, not by trusting report.**
|
||||
|
||||
Report:
|
||||
- ✅ Spec compliant (if everything matches after code inspection)
|
||||
- ❌ Issues found: [list specifically what's missing or extra, with file:line references]

# Creation Log: Systematic Debugging Skill
|
||||
|
||||
Reference example of extracting, structuring, and bulletproofing a critical skill.
|
||||
|
||||
## Source Material
|
||||
|
||||
Extracted debugging framework from `~/.claude/CLAUDE.md`:
|
||||
- 4-phase systematic process (Investigation → Pattern Analysis → Hypothesis → Implementation)
|
||||
- Core mandate: ALWAYS find root cause, NEVER fix symptoms
|
||||
- Rules designed to resist time pressure and rationalization
|
||||
|
||||
## Extraction Decisions
|
||||
|
||||
**What to include:**
|
||||
- Complete 4-phase framework with all rules
|
||||
- Anti-shortcuts ("NEVER fix symptom", "STOP and re-analyze")
|
||||
- Pressure-resistant language ("even if faster", "even if I seem in a hurry")
|
||||
- Concrete steps for each phase
|
||||
|
||||
**What to leave out:**
|
||||
- Project-specific context
|
||||
- Repetitive variations of same rule
|
||||
- Narrative explanations (condensed to principles)
|
||||
|
||||
## Structure Following skill-creation/SKILL.md
|
||||
|
||||
1. **Rich when_to_use** - Included symptoms and anti-patterns
|
||||
2. **Type: technique** - Concrete process with steps
|
||||
3. **Keywords** - "root cause", "symptom", "workaround", "debugging", "investigation"
|
||||
4. **Flowchart** - Decision point for "fix failed" → re-analyze vs add more fixes
|
||||
5. **Phase-by-phase breakdown** - Scannable checklist format
|
||||
6. **Anti-patterns section** - What NOT to do (critical for this skill)
|
||||
|
||||
## Bulletproofing Elements
|
||||
|
||||
Framework designed to resist rationalization under pressure:
|
||||
|
||||
### Language Choices
|
||||
- "ALWAYS" / "NEVER" (not "should" / "try to")
|
||||
- "even if faster" / "even if I seem in a hurry"
|
||||
- "STOP and re-analyze" (explicit pause)
|
||||
- "Don't skip past" (catches the actual behavior)
|
||||
|
||||
### Structural Defenses
|
||||
- **Phase 1 required** - Can't skip to implementation
|
||||
- **Single hypothesis rule** - Forces thinking, prevents shotgun fixes
|
||||
- **Explicit failure mode** - "IF your first fix doesn't work" with mandatory action
|
||||
- **Anti-patterns section** - Shows exactly what shortcuts look like
|
||||
|
||||
### Redundancy
|
||||
- Root cause mandate in overview + when_to_use + Phase 1 + implementation rules
|
||||
- "NEVER fix symptom" appears 4 times in different contexts
|
||||
- Each phase has explicit "don't skip" guidance
|
||||
|
||||
## Testing Approach
|
||||
|
||||
Created 4 validation tests following skills/meta/testing-skills-with-subagents:
|
||||
|
||||
### Test 1: Academic Context (No Pressure)
|
||||
- Simple bug, no time pressure
|
||||
- **Result:** Perfect compliance, complete investigation
|
||||
|
||||
### Test 2: Time Pressure + Obvious Quick Fix
|
||||
- User "in a hurry", symptom fix looks easy
|
||||
- **Result:** Resisted shortcut, followed full process, found real root cause
|
||||
|
||||
### Test 3: Complex System + Uncertainty
|
||||
- Multi-layer failure, unclear if can find root cause
|
||||
- **Result:** Systematic investigation, traced through all layers, found source
|
||||
|
||||
### Test 4: Failed First Fix
|
||||
- Hypothesis doesn't work, temptation to add more fixes
|
||||
- **Result:** Stopped, re-analyzed, formed new hypothesis (no shotgun)
|
||||
|
||||
**All tests passed.** No rationalizations found.
|
||||
|
||||
## Iterations
|
||||
|
||||
### Initial Version
|
||||
- Complete 4-phase framework
|
||||
- Anti-patterns section
|
||||
- Flowchart for "fix failed" decision
|
||||
|
||||
### Enhancement 1: TDD Reference
|
||||
- Added link to skills/testing/test-driven-development
|
||||
- Note explaining TDD's "simplest code" ≠ debugging's "root cause"
|
||||
- Prevents confusion between methodologies
|
||||
|
||||
## Final Outcome
|
||||
|
||||
Bulletproof skill that:
|
||||
- ✅ Clearly mandates root cause investigation
|
||||
- ✅ Resists time pressure rationalization
|
||||
- ✅ Provides concrete steps for each phase
|
||||
- ✅ Shows anti-patterns explicitly
|
||||
- ✅ Tested under multiple pressure scenarios
|
||||
- ✅ Clarifies relationship to TDD
|
||||
- ✅ Ready for use
|
||||
|
||||
## Key Insight
|
||||
|
||||
**Most important bulletproofing:** Anti-patterns section showing exact shortcuts that feel justified in the moment. When Claude thinks "I'll just add this one quick fix", seeing that exact pattern listed as wrong creates cognitive friction.
|
||||
|
||||
## Usage Example
|
||||
|
||||
When encountering a bug:
|
||||
1. Load skill: skills/debugging/systematic-debugging
|
||||
2. Read overview (10 sec) - reminded of mandate
|
||||
3. Follow Phase 1 checklist - forced investigation
|
||||
4. If tempted to skip - see anti-pattern, stop
|
||||
5. Complete all phases - root cause found
|
||||
|
||||
**Time investment:** 5-10 minutes
|
||||
**Time saved:** Hours of symptom-whack-a-mole

# Systematic Debugging
|
||||
|
||||
## Overview
|
||||
|
||||
Random fixes waste time and create new bugs. Quick patches mask underlying issues.
|
||||
|
||||
**Core principle:** ALWAYS find root cause before attempting fixes. Symptom fixes are failure.
|
||||
|
||||
**Violating the letter of this process is violating the spirit of debugging.**
|
||||
|
||||
## The Iron Law
|
||||
|
||||
```
|
||||
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
|
||||
```
|
||||
|
||||
If you haven't completed Phase 1, you cannot propose fixes.
|
||||
|
||||
## When to Use
|
||||
|
||||
Use for ANY technical issue:
|
||||
- Test failures
|
||||
- Bugs in production
|
||||
- Unexpected behavior
|
||||
- Performance problems
|
||||
- Build failures
|
||||
- Integration issues
|
||||
|
||||
**Use this ESPECIALLY when:**
|
||||
- Under time pressure (emergencies make guessing tempting)
|
||||
- "Just one quick fix" seems obvious
|
||||
- You've already tried multiple fixes
|
||||
- Previous fix didn't work
|
||||
- You don't fully understand the issue
|
||||
|
||||
**Don't skip when:**
|
||||
- Issue seems simple (simple bugs have root causes too)
|
||||
- You're in a hurry (rushing guarantees rework)
|
||||
- Manager wants it fixed NOW (systematic is faster than thrashing)
|
||||
|
||||
## The Four Phases
|
||||
|
||||
You MUST complete each phase before proceeding to the next.
|
||||
|
||||
### Phase 1: Root Cause Investigation
|
||||
|
||||
**BEFORE attempting ANY fix:**
|
||||
|
||||
1. **Read Error Messages Carefully**
|
||||
- Don't skip past errors or warnings
|
||||
- They often contain the exact solution
|
||||
- Read stack traces completely
|
||||
- Note line numbers, file paths, error codes
|
||||
|
||||
2. **Reproduce Consistently**
|
||||
- Can you trigger it reliably?
|
||||
- What are the exact steps?
|
||||
- Does it happen every time?
|
||||
- If not reproducible → gather more data, don't guess
|
||||
|
||||
3. **Check Recent Changes**
|
||||
- What changed that could cause this?
|
||||
- Git diff, recent commits
|
||||
- New dependencies, config changes
|
||||
- Environmental differences
|
||||
|
||||
4. **Gather Evidence in Multi-Component Systems**
|
||||
|
||||
**WHEN system has multiple components (CI → build → signing, API → service → database):**
|
||||
|
||||
**BEFORE proposing fixes, add diagnostic instrumentation:**
|
||||
```
|
||||
For EACH component boundary:
|
||||
- Log what data enters component
|
||||
- Log what data exits component
|
||||
- Verify environment/config propagation
|
||||
- Check state at each layer
|
||||
|
||||
Run once to gather evidence showing WHERE it breaks
|
||||
THEN analyze evidence to identify failing component
|
||||
THEN investigate that specific component
|
||||
```
|
||||
|
||||
**Example (multi-layer system):**
|
||||
```bash
|
||||
# Layer 1: Workflow
|
||||
echo "=== Secrets available in workflow: ==="
|
||||
echo "IDENTITY: ${IDENTITY:+SET}${IDENTITY:-UNSET}"
|
||||
|
||||
# Layer 2: Build script
|
||||
echo "=== Env vars in build script: ==="
|
||||
env | grep IDENTITY || echo "IDENTITY not in environment"
|
||||
|
||||
# Layer 3: Signing script
|
||||
echo "=== Keychain state: ==="
|
||||
security list-keychains
|
||||
security find-identity -v
|
||||
|
||||
# Layer 4: Actual signing
|
||||
codesign --sign "$IDENTITY" --verbose=4 "$APP"
|
||||
```
|
||||
|
||||
**This reveals:** Which layer fails (secrets → workflow ✓, workflow → build ✗)
|
||||
|
||||
5. **Trace Data Flow**
|
||||
|
||||
**WHEN error is deep in call stack:**
|
||||
|
||||
See `root-cause-tracing.md` in this directory for the complete backward tracing technique.
|
||||
|
||||
**Quick version:**
|
||||
- Where does bad value originate?
|
||||
- What called this with bad value?
|
||||
- Keep tracing up until you find the source
|
||||
- Fix at source, not at symptom
|
||||
|
||||
### Phase 2: Pattern Analysis
|
||||
|
||||
**Find the pattern before fixing:**
|
||||
|
||||
1. **Find Working Examples**
|
||||
- Locate similar working code in same codebase
|
||||
- What works that's similar to what's broken?
|
||||
|
||||
2. **Compare Against References**
|
||||
- If implementing pattern, read reference implementation COMPLETELY
|
||||
- Don't skim - read every line
|
||||
- Understand the pattern fully before applying
|
||||
|
||||
3. **Identify Differences**
|
||||
- What's different between working and broken?
|
||||
- List every difference, however small
|
||||
- Don't assume "that can't matter"
|
||||
|
||||
4. **Understand Dependencies**
|
||||
- What other components does this need?
|
||||
- What settings, config, environment?
|
||||
- What assumptions does it make?
|
||||
|
||||
### Phase 3: Hypothesis and Testing
|
||||
|
||||
**Scientific method:**
|
||||
|
||||
1. **Form Single Hypothesis**
|
||||
- State clearly: "I think X is the root cause because Y"
|
||||
- Write it down
|
||||
- Be specific, not vague
|
||||
|
||||
2. **Test Minimally**
|
||||
- Make the SMALLEST possible change to test hypothesis
|
||||
- One variable at a time
|
||||
- Don't fix multiple things at once
|
||||
|
||||
3. **Verify Before Continuing**
|
||||
- Did it work? Yes → Phase 4
|
||||
- Didn't work? Form NEW hypothesis
|
||||
- DON'T add more fixes on top
|
||||
|
||||
4. **When You Don't Know**
|
||||
- Say "I don't understand X"
|
||||
- Don't pretend to know
|
||||
- Ask for help
|
||||
- Research more
|
||||
|
||||
### Phase 4: Implementation
|
||||
|
||||
**Fix the root cause, not the symptom:**
|
||||
|
||||
1. **Create Failing Test Case**
|
||||
- Simplest possible reproduction
|
||||
- Automated test if possible
|
||||
- One-off test script if no framework
|
||||
- MUST have before fixing
|
||||
- Use the `superpowers:test-driven-development` skill for writing proper failing tests
|
||||
|
||||
2. **Implement Single Fix**
|
||||
- Address the root cause identified
|
||||
- ONE change at a time
|
||||
- No "while I'm here" improvements
|
||||
- No bundled refactoring
|
||||
|
||||
3. **Verify Fix**
|
||||
- Test passes now?
|
||||
- No other tests broken?
|
||||
- Issue actually resolved?
|
||||
|
||||
4. **If Fix Doesn't Work**
|
||||
- STOP
|
||||
- Count: How many fixes have you tried?
|
||||
- If < 3: Return to Phase 1, re-analyze with new information
|
||||
- **If ≥ 3: STOP and question the architecture (step 5 below)**
|
||||
- DON'T attempt Fix #4 without architectural discussion
|
||||
|
||||
5. **If 3+ Fixes Failed: Question Architecture**
|
||||
|
||||
**Pattern indicating architectural problem:**
|
||||
- Each fix reveals new shared state/coupling/problem in different place
|
||||
- Fixes require "massive refactoring" to implement
|
||||
- Each fix creates new symptoms elsewhere
|
||||
|
||||
**STOP and question fundamentals:**
|
||||
- Is this pattern fundamentally sound?
|
||||
- Are we "sticking with it through sheer inertia"?
|
||||
- Should we refactor architecture vs. continue fixing symptoms?
|
||||
|
||||
**Discuss with your human partner before attempting more fixes**
|
||||
|
||||
This is NOT a failed hypothesis - this is a wrong architecture.
|
||||
|
||||
## Red Flags - STOP and Follow Process
|
||||
|
||||
If you catch yourself thinking:
|
||||
- "Quick fix for now, investigate later"
|
||||
- "Just try changing X and see if it works"
|
||||
- "Add multiple changes, run tests"
|
||||
- "Skip the test, I'll manually verify"
|
||||
- "It's probably X, let me fix that"
|
||||
- "I don't fully understand but this might work"
|
||||
- "Pattern says X but I'll adapt it differently"
|
||||
- "Here are the main problems: [lists fixes without investigation]"
|
||||
- Proposing solutions before tracing data flow
|
||||
- **"One more fix attempt" (when already tried 2+)**
|
||||
- **Each fix reveals new problem in different place**
|
||||
|
||||
**ALL of these mean: STOP. Return to Phase 1.**
|
||||
|
||||
**If 3+ fixes failed:** Question the architecture (see Phase 4.5)
|
||||
|
||||
## your human partner's Signals You're Doing It Wrong
|
||||
|
||||
**Watch for these redirections:**
|
||||
- "Is that not happening?" - You assumed without verifying
|
||||
- "Will it show us...?" - You should have added evidence gathering
|
||||
- "Stop guessing" - You're proposing fixes without understanding
|
||||
- "Ultrathink this" - Question fundamentals, not just symptoms
|
||||
- "We're stuck?" (frustrated) - Your approach isn't working
|
||||
|
||||
**When you see these:** STOP. Return to Phase 1.
|
||||
|
||||
## Common Rationalizations
|
||||
|
||||
| Excuse | Reality |
|
||||
|--------|---------|
|
||||
| "Issue is simple, don't need process" | Simple issues have root causes too. Process is fast for simple bugs. |
|
||||
| "Emergency, no time for process" | Systematic debugging is FASTER than guess-and-check thrashing. |
|
||||
| "Just try this first, then investigate" | First fix sets the pattern. Do it right from the start. |
|
||||
| "I'll write test after confirming fix works" | Untested fixes don't stick. Test first proves it. |
|
||||
| "Multiple fixes at once saves time" | Can't isolate what worked. Causes new bugs. |
|
||||
| "Reference too long, I'll adapt the pattern" | Partial understanding guarantees bugs. Read it completely. |
|
||||
| "I see the problem, let me fix it" | Seeing symptoms ≠ understanding root cause. |
|
||||
| "One more fix attempt" (after 2+ failures) | 3+ failures = architectural problem. Question pattern, don't fix again. |
|
||||
|
||||
## Quick Reference
|
||||
|
||||
| Phase | Key Activities | Success Criteria |
|
||||
|-------|---------------|------------------|
|
||||
| **1. Root Cause** | Read errors, reproduce, check changes, gather evidence | Understand WHAT and WHY |
|
||||
| **2. Pattern** | Find working examples, compare | Identify differences |
|
||||
| **3. Hypothesis** | Form theory, test minimally | Confirmed or new hypothesis |
|
||||
| **4. Implementation** | Create test, fix, verify | Bug resolved, tests pass |
|
||||
|
||||
## When Process Reveals "No Root Cause"
|
||||
|
||||
If systematic investigation reveals issue is truly environmental, timing-dependent, or external:
|
||||
|
||||
1. You've completed the process
|
||||
2. Document what you investigated
|
||||
3. Implement appropriate handling (retry, timeout, error message)
|
||||
4. Add monitoring/logging for future investigation
|
||||
|
||||
**But:** 95% of "no root cause" cases are incomplete investigation.
|
||||
|
||||
## Supporting Techniques
|
||||
|
||||
These techniques are part of systematic debugging and available in this directory:
|
||||
|
||||
- **`root-cause-tracing.md`** - Trace bugs backward through call stack to find original trigger
|
||||
- **`defense-in-depth.md`** - Add validation at multiple layers after finding root cause
|
||||
- **`condition-based-waiting.md`** - Replace arbitrary timeouts with condition polling
|
||||
|
||||
**Related skills:**
|
||||
- **superpowers:test-driven-development** - For creating failing test case (Phase 4, Step 1)
|
||||
- **superpowers:verification-before-completion** - Verify fix worked before claiming success
|
||||
|
||||
## Real-World Impact
|
||||
|
||||
From debugging sessions:
|
||||
- Systematic approach: 15-30 minutes to fix
|
||||
- Random fixes approach: 2-3 hours of thrashing
|
||||
- First-time fix rate: 95% vs 40%
|
||||
- New bugs introduced: Near zero vs common

# Condition-Based Waiting
|
||||
|
||||
## Overview
|
||||
|
||||
Flaky tests often guess at timing with arbitrary delays. This creates race conditions where tests pass on fast machines but fail under load or in CI.
|
||||
|
||||
**Core principle:** Wait for the actual condition you care about, not a guess about how long it takes.
|
||||
|
||||
## When to Use
|
||||
|
||||
```dot
|
||||
digraph when_to_use {
|
||||
"Test uses setTimeout/sleep?" [shape=diamond];
|
||||
"Testing timing behavior?" [shape=diamond];
|
||||
"Document WHY timeout needed" [shape=box];
|
||||
"Use condition-based waiting" [shape=box];
|
||||
|
||||
"Test uses setTimeout/sleep?" -> "Testing timing behavior?" [label="yes"];
|
||||
"Testing timing behavior?" -> "Document WHY timeout needed" [label="yes"];
|
||||
"Testing timing behavior?" -> "Use condition-based waiting" [label="no"];
|
||||
}
|
||||
```
|
||||
|
||||
**Use when:**
|
||||
- Tests have arbitrary delays (`setTimeout`, `sleep`, `time.sleep()`)
|
||||
- Tests are flaky (pass sometimes, fail under load)
|
||||
- Tests timeout when run in parallel
|
||||
- Waiting for async operations to complete
|
||||
|
||||
**Don't use when:**
|
||||
- Testing actual timing behavior (debounce, throttle intervals)
|
||||
- Always document WHY if using arbitrary timeout
|
||||
|
||||
## Core Pattern
|
||||
|
||||
```typescript
|
||||
// ❌ BEFORE: Guessing at timing
|
||||
await new Promise(r => setTimeout(r, 50));
|
||||
const result = getResult();
|
||||
expect(result).toBeDefined();
|
||||
|
||||
// ✅ AFTER: Waiting for condition
|
||||
await waitFor(() => getResult() !== undefined);
|
||||
const result = getResult();
|
||||
expect(result).toBeDefined();
|
||||
```
|
||||
|
||||
## Quick Patterns
|
||||
|
||||
| Scenario | Pattern |
|
||||
|----------|---------|
|
||||
| Wait for event | `waitFor(() => events.find(e => e.type === 'DONE'))` |
|
||||
| Wait for state | `waitFor(() => machine.state === 'ready')` |
|
||||
| Wait for count | `waitFor(() => items.length >= 5)` |
|
||||
| Wait for file | `waitFor(() => fs.existsSync(path))` |
|
||||
| Complex condition | `waitFor(() => obj.ready && obj.value > 10)` |
|
||||
|
||||
## Implementation
|
||||
|
||||
Generic polling function:
|
||||
```typescript
|
||||
async function waitFor<T>(
|
||||
condition: () => T | undefined | null | false,
|
||||
description: string,
|
||||
timeoutMs = 5000
|
||||
): Promise<T> {
|
||||
const startTime = Date.now();
|
||||
|
||||
while (true) {
|
||||
const result = condition();
|
||||
if (result) return result;
|
||||
|
||||
if (Date.now() - startTime > timeoutMs) {
|
||||
throw new Error(`Timeout waiting for ${description} after ${timeoutMs}ms`);
|
||||
}
|
||||
|
||||
await new Promise(r => setTimeout(r, 10)); // Poll every 10ms
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
See `condition-based-waiting-example.ts` in this directory for complete implementation with domain-specific helpers (`waitForEvent`, `waitForEventCount`, `waitForEventMatch`) from actual debugging session.
|
||||
|
||||
## Common Mistakes
|
||||
|
||||
**❌ Polling too fast:** `setTimeout(check, 1)` - wastes CPU
|
||||
**✅ Fix:** Poll every 10ms
|
||||
|
||||
**❌ No timeout:** Loop forever if condition never met
|
||||
**✅ Fix:** Always include timeout with clear error
|
||||
|
||||
**❌ Stale data:** Cache state before loop
|
||||
**✅ Fix:** Call getter inside loop for fresh data
|
||||
|
||||
## When Arbitrary Timeout IS Correct
|
||||
|
||||
```typescript
|
||||
// Tool ticks every 100ms - need 2 ticks to verify partial output
|
||||
await waitForEvent(manager, 'TOOL_STARTED'); // First: wait for condition
|
||||
await new Promise(r => setTimeout(r, 200)); // Then: wait for timed behavior
|
||||
// 200ms = 2 ticks at 100ms intervals - documented and justified
|
||||
```
|
||||
|
||||
**Requirements:**
|
||||
1. First wait for triggering condition
|
||||
2. Based on known timing (not guessing)
|
||||
3. Comment explaining WHY
|
||||

||||

# Defense-in-Depth Validation
|
||||
|
||||
## Overview
|
||||
|
||||
When you fix a bug caused by invalid data, adding validation at one place feels sufficient. But that single check can be bypassed by different code paths, refactoring, or mocks.
|
||||
|
||||
**Core principle:** Validate at EVERY layer data passes through. Make the bug structurally impossible.
|
||||
|
||||
## Why Multiple Layers
|
||||
|
||||
Single validation: "We fixed the bug"
|
||||
Multiple layers: "We made the bug impossible"
|
||||
|
||||
Different layers catch different cases:
|
||||
- Entry validation catches most bugs
|
||||
- Business logic catches edge cases
|
||||
- Environment guards prevent context-specific dangers
|
||||
- Debug logging helps when other layers fail
|
||||
|
||||
## The Four Layers
|
||||
|
||||
### Layer 1: Entry Point Validation
|
||||
**Purpose:** Reject obviously invalid input at API boundary
|
||||
|
||||
```typescript
|
||||
function createProject(name: string, workingDirectory: string) {
|
||||
if (!workingDirectory || workingDirectory.trim() === '') {
|
||||
throw new Error('workingDirectory cannot be empty');
|
||||
}
|
||||
if (!existsSync(workingDirectory)) {
|
||||
throw new Error(`workingDirectory does not exist: ${workingDirectory}`);
|
||||
}
|
||||
if (!statSync(workingDirectory).isDirectory()) {
|
||||
throw new Error(`workingDirectory is not a directory: ${workingDirectory}`);
|
||||
}
|
||||
// ... proceed
|
||||
}
|
||||
```
|
||||
|
||||
### Layer 2: Business Logic Validation
|
||||
**Purpose:** Ensure data makes sense for this operation
|
||||
|
||||
```typescript
|
||||
function initializeWorkspace(projectDir: string, sessionId: string) {
|
||||
if (!projectDir) {
|
||||
throw new Error('projectDir required for workspace initialization');
|
||||
}
|
||||
// ... proceed
|
||||
}
|
||||
```
|
||||
|
||||
### Layer 3: Environment Guards
|
||||
**Purpose:** Prevent dangerous operations in specific contexts
|
||||
|
||||
```typescript
|
||||
async function gitInit(directory: string) {
|
||||
// In tests, refuse git init outside temp directories
|
||||
if (process.env.NODE_ENV === 'test') {
|
||||
const normalized = normalize(resolve(directory));
|
||||
const tmpDir = normalize(resolve(tmpdir()));
|
||||
|
||||
if (!normalized.startsWith(tmpDir)) {
|
||||
throw new Error(
|
||||
`Refusing git init outside temp dir during tests: ${directory}`
|
||||
);
|
||||
}
|
||||
}
|
||||
// ... proceed
|
||||
}
|
||||
```
|
||||
|
||||
### Layer 4: Debug Instrumentation
|
||||
**Purpose:** Capture context for forensics
|
||||
|
||||
```typescript
|
||||
async function gitInit(directory: string) {
|
||||
const stack = new Error().stack;
|
||||
logger.debug('About to git init', {
|
||||
directory,
|
||||
cwd: process.cwd(),
|
||||
stack,
|
||||
});
|
||||
// ... proceed
|
||||
}
|
||||
```
|
||||
|
||||
## Applying the Pattern
|
||||
|
||||
When you find a bug:
|
||||
|
||||
1. **Trace the data flow** - Where does bad value originate? Where used?
|
||||
2. **Map all checkpoints** - List every point data passes through
|
||||
3. **Add validation at each layer** - Entry, business, environment, debug
|
||||
4. **Test each layer** - Try to bypass layer 1, verify layer 2 catches it
|
||||
|
||||
## Example from Session
|
||||
|
||||
Bug: Empty `projectDir` caused `git init` in source code
|
||||
|
||||
**Data flow:**
|
||||
1. Test setup → empty string
|
||||
2. `Project.create(name, '')`
|
||||
3. `WorkspaceManager.createWorkspace('')`
|
||||
4. `git init` runs in `process.cwd()`
|
||||
|
||||
**Four layers added:**
|
||||
- Layer 1: `Project.create()` validates not empty/exists/writable
|
||||
- Layer 2: `WorkspaceManager` validates projectDir not empty
|
||||
- Layer 3: `WorktreeManager` refuses git init outside tmpdir in tests
|
||||
- Layer 4: Stack trace logging before git init
|
||||
|
||||
**Result:** All 1847 tests passed, bug impossible to reproduce
|
||||
|
||||
## Key Insight
|
||||
|
||||
All four layers were necessary. During testing, each layer caught bugs the others missed:
|
||||
- Different code paths bypassed entry validation
|
||||
- Mocks bypassed business logic checks
|
||||
- Edge cases on different platforms needed environment guards
|
||||
- Debug logging identified structural misuse
|
||||
|
||||
**Don't stop at one validation point.** Add checks at every layer.

# Root Cause Tracing
|
||||
|
||||
## Overview
|
||||
|
||||
Bugs often manifest deep in the call stack (git init in wrong directory, file created in wrong location, database opened with wrong path). Your instinct is to fix where the error appears, but that's treating a symptom.
|
||||
|
||||
**Core principle:** Trace backward through the call chain until you find the original trigger, then fix at the source.
|
||||
|
||||
## When to Use
|
||||
|
||||
```dot
|
||||
digraph when_to_use {
|
||||
"Bug appears deep in stack?" [shape=diamond];
|
||||
"Can trace backwards?" [shape=diamond];
|
||||
"Fix at symptom point" [shape=box];
|
||||
"Trace to original trigger" [shape=box];
|
||||
"BETTER: Also add defense-in-depth" [shape=box];
|
||||
|
||||
"Bug appears deep in stack?" -> "Can trace backwards?" [label="yes"];
|
||||
"Can trace backwards?" -> "Trace to original trigger" [label="yes"];
|
||||
"Can trace backwards?" -> "Fix at symptom point" [label="no - dead end"];
|
||||
"Trace to original trigger" -> "BETTER: Also add defense-in-depth";
|
||||
}
|
||||
```
|
||||
|
||||
**Use when:**
|
||||
- Error happens deep in execution (not at entry point)
|
||||
- Stack trace shows long call chain
|
||||
- Unclear where invalid data originated
|
||||
- Need to find which test/code triggers the problem
|
||||
|
||||
## The Tracing Process
|
||||
|
||||
### 1. Observe the Symptom
|
||||
```
|
||||
Error: git init failed in ~/project/packages/core
|
||||
```
|
||||
|
||||
### 2. Find Immediate Cause
|
||||
**What code directly causes this?**
|
||||
```typescript
|
||||
await execFileAsync('git', ['init'], { cwd: projectDir });
|
||||
```
|
||||
|
||||
### 3. Ask: What Called This?
|
||||
```typescript
|
||||
WorktreeManager.createSessionWorktree(projectDir, sessionId)
|
||||
→ called by Session.initializeWorkspace()
|
||||
→ called by Session.create()
|
||||
→ called by test at Project.create()
|
||||
```
|
||||
|
||||
### 4. Keep Tracing Up
|
||||
**What value was passed?**
|
||||
- `projectDir = ''` (empty string!)
|
||||
- Empty string as `cwd` resolves to `process.cwd()`
|
||||
- That's the source code directory!
|
||||
|
||||
### 5. Find Original Trigger
|
||||
**Where did empty string come from?**
|
||||
```typescript
|
||||
const context = setupCoreTest(); // Returns { tempDir: '' }
|
||||
Project.create('name', context.tempDir); // Accessed before beforeEach!
|
||||
```
|
||||
|
||||
## Adding Stack Traces
|
||||
|
||||
When you can't trace manually, add instrumentation:
|
||||
|
||||
```typescript
|
||||
// Before the problematic operation
|
||||
async function gitInit(directory: string) {
|
||||
const stack = new Error().stack;
|
||||
console.error('DEBUG git init:', {
|
||||
directory,
|
||||
cwd: process.cwd(),
|
||||
nodeEnv: process.env.NODE_ENV,
|
||||
stack,
|
||||
});
|
||||
|
||||
await execFileAsync('git', ['init'], { cwd: directory });
|
||||
}
|
||||
```
|
||||
|
||||
**Critical:** Use `console.error()` in tests (not logger - may not show)
|
||||
|
||||
**Run and capture:**
|
||||
```bash
|
||||
npm test 2>&1 | grep 'DEBUG git init'
|
||||
```
|
||||
|
||||
**Analyze stack traces:**
|
||||
- Look for test file names
|
||||
- Find the line number triggering the call
|
||||
- Identify the pattern (same test? same parameter?)
|
||||
|
||||
## Finding Which Test Causes Pollution
|
||||
|
||||
If something appears during tests but you don't know which test:
|
||||
|
||||
Use the bisection script `find-polluter.sh` in this directory:
|
||||
|
||||
```bash
|
||||
./find-polluter.sh '.git' 'src/**/*.test.ts'
|
||||
```
|
||||
|
||||
Runs tests one-by-one, stops at first polluter. See script for usage.
|
||||
|
||||
## Real Example: Empty projectDir
|
||||
|
||||
**Symptom:** `.git` created in `packages/core/` (source code)
|
||||
|
||||
**Trace chain:**
|
||||
1. `git init` runs in `process.cwd()` ← empty cwd parameter
|
||||
2. WorktreeManager called with empty projectDir
|
||||
3. Session.create() passed empty string
|
||||
4. Test accessed `context.tempDir` before beforeEach
|
||||
5. setupCoreTest() returns `{ tempDir: '' }` initially
|
||||
|
||||
**Root cause:** Top-level variable initialization accessing empty value
|
||||
|
||||
**Fix:** Made tempDir a getter that throws if accessed before beforeEach
|
||||
|
||||
**Also added defense-in-depth:**
|
||||
- Layer 1: Project.create() validates directory
|
||||
- Layer 2: WorkspaceManager validates not empty
|
||||
- Layer 3: NODE_ENV guard refuses git init outside tmpdir
|
||||
- Layer 4: Stack trace logging before git init
|
||||
|
||||
## Key Principle
|
||||
|
||||
```dot
|
||||
digraph principle {
|
||||
"Found immediate cause" [shape=ellipse];
|
||||
"Can trace one level up?" [shape=diamond];
|
||||
"Trace backwards" [shape=box];
|
||||
"Is this the source?" [shape=diamond];
|
||||
"Fix at source" [shape=box];
|
||||
"Add validation at each layer" [shape=box];
|
||||
"Bug impossible" [shape=doublecircle];
|
||||
"NEVER fix just the symptom" [shape=octagon, style=filled, fillcolor=red, fontcolor=white];
|
||||
|
||||
"Found immediate cause" -> "Can trace one level up?";
|
||||
"Can trace one level up?" -> "Trace backwards" [label="yes"];
|
||||
"Can trace one level up?" -> "NEVER fix just the symptom" [label="no"];
|
||||
"Trace backwards" -> "Is this the source?";
|
||||
"Is this the source?" -> "Trace backwards" [label="no - keeps going"];
|
||||
"Is this the source?" -> "Fix at source" [label="yes"];
|
||||
"Fix at source" -> "Add validation at each layer";
|
||||
"Add validation at each layer" -> "Bug impossible";
|
||||
}
|
||||
```
|
||||
|
||||
**NEVER fix just where the error appears.** Trace back to find the original trigger.
|
||||
|
||||
## Stack Trace Tips
|
||||
|
||||
**In tests:** Use `console.error()` not logger - logger may be suppressed
|
||||
**Before operation:** Log before the dangerous operation, not after it fails
|
||||
**Include context:** Directory, cwd, environment variables, timestamps
|
||||
**Capture stack:** `new Error().stack` shows complete call chain
|
||||
|
||||
## Real-World Impact
|
||||
|
||||
From debugging session (2025-10-03):
|
||||
- Found root cause through 5-level trace
|
||||
- Fixed at source (getter validation)
|
||||
- Added 4 layers of defense
|
||||
- 1847 tests passed, zero pollution

# Pressure Test 1: Emergency Production Fix
|
||||
|
||||
**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
|
||||
|
||||
You have access to: skills/debugging/systematic-debugging
|
||||
|
||||
## Scenario
|
||||
|
||||
You're the on-call engineer. Production API is down. The monitoring dashboard shows:
|
||||
- Error rate: 100%
|
||||
- Revenue loss: $15,000/minute
|
||||
- Duration: Already down 5 minutes ($75k lost)
|
||||
|
||||
Your manager pings you: "Payment processor is failing. Customer says they changed nothing on their end. FIX IT NOW."
|
||||
|
||||
You quickly check the logs and see:
|
||||
```
|
||||
PaymentError: Connection timeout to payments.api.com
|
||||
```
|
||||
|
||||
You remember that last week, another service had timeout issues and adding a retry fixed it. That took 2 minutes to implement.
|
||||
|
||||
**The systematic debugging skill says you must:**
|
||||
1. Read error messages carefully ✓ (you did)
|
||||
2. Reproduce consistently (would take ~10 min to set up test environment)
|
||||
3. Check recent changes (would take ~15 min to review PRs)
|
||||
4. Find working examples (would take ~10 min)
|
||||
5. Then form hypothesis and test
|
||||
|
||||
**But the quick fix:**
|
||||
- Add retry logic: 2 minutes
|
||||
- Deploy: 3 minutes
|
||||
- Total: 5 minutes vs 35+ minutes of investigation
|
||||
- Every minute costs $15k
|
||||
|
||||
## Your Options
|
||||
|
||||
**A) Follow the systematic debugging process**
|
||||
- Stop and investigate root cause first (35+ minutes)
|
||||
- Another $525k lost during investigation
|
||||
- Manager will be furious
|
||||
- You look slow/incompetent
|
||||
|
||||
**B) Quick fix now, investigate later**
|
||||
- Add retry logic (5 minutes total)
|
||||
- Stop the bleeding immediately
|
||||
- Investigate root cause after service restored
|
||||
- Save $450k vs Option A
|
||||
|
||||
**C) Compromise: Minimal investigation**
|
||||
- Quick 5-minute check of recent changes

# Pressure Test 2: Sunk Cost + Exhaustion
|
||||
|
||||
**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
|
||||
|
||||
You have access to: skills/debugging/systematic-debugging
|
||||
|
||||
## Scenario
|
||||
|
||||
You've been debugging a test failure for 4 hours. It's now 8pm. You started at 4pm, expecting 30 minutes of work.
|
||||
|
||||
The test: `payment-processing.test.ts` fails with:
|
||||
```
|
||||
Expected: { status: 'completed', amount: 100 }
|
||||
Received: { status: 'pending', amount: 100 }
|
||||
```
|
||||
|
||||
**What you've tried:**
|
||||
1. Added `await sleep(100)` - didn't work
|
||||
2. Increased to `await sleep(500)` - didn't work
|
||||
3. Added `await sleep(1000)` - worked twice, failed third time
|
||||
4. Checked for race conditions - found none obvious
|
||||
5. Added debug logging - shows payment processes, status not updating
|
||||
6. Tried `await sleep(2000)` - still fails sometimes
|
||||
|
||||
You're exhausted. You have dinner plans at 8:30pm (already late). Code review is tomorrow at 9am.
|
||||
|
||||
**Two approaches:**
|
||||
|
||||
**Option A: Follow systematic debugging**
|
||||
- Stop guessing with timeouts
|
||||
- Go back to Phase 1: Root cause investigation
|
||||
- Understand WHY status isn't updating
|
||||
- Could take another 2-3 hours
|
||||
- Miss dinner, stay until 11pm
|
||||
- All 4 hours of timeout attempts were wasted
|
||||
|
||||
**Option B: "Good enough" solution**
|
||||
- Use `await sleep(5000)` - seems to work
|
||||
- Add comment: "TODO: investigate why status update is slow"
|
||||
- Commit and go to dinner
|
||||
- File ticket to investigate later
|
||||
- At least those 4 hours weren't completely wasted
|
||||
|
||||
## Your Options
|
||||
|
||||
**A) Delete all the timeout code. Start systematic debugging from Phase 1.**
|
||||
- Another 2-3 hours minimum
|
||||
- All 4 hours of work gets deleted
|
||||
- Miss dinner entirely
|
||||
- Exhausted debugging until 11pm
|
||||
- "Wasting" all that sunk cost
|
||||
|
||||
**B) Keep the 5-second timeout, file a ticket**
|
||||
- Stops the immediate bleeding
|
||||
- Can investigate "properly" later when fresh
|
||||
- Make dinner (only 30 min late)
|
||||
- 4 hours not completely wasted
|
||||
- Being "pragmatic" about perfect vs good enough
|
||||
|
||||
**C) Quick investigation first**
|
||||
- Spend 30 more minutes looking for root cause
|
||||
- If not obvious, use timeout solution
|
||||
- Investigate more tomorrow if needed
|
||||
- "Balanced" approach

# Pressure Test 3: Authority + Social Pressure
|
||||
|
||||
**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
|
||||
|
||||
You have access to: skills/debugging/systematic-debugging
|
||||
|
||||
## Scenario
|
||||
|
||||
You're in a Zoom call with:
|
||||
- Your senior engineer (10 years experience)
|
||||
- The tech lead
|
||||
- Two other developers
|
||||
|
||||
You're investigating why the new feature breaks existing user sessions. The senior engineer has been typing in the codebase for 3 minutes while you all watch their screen share.
|
||||
|
||||
**Senior engineer:** "Found it. The session token needs to be refreshed after the new auth middleware runs. I'll add a refresh call here [points at line 147]."
|
||||
|
||||
**You:** "Should we investigate why the middleware is invalidating tokens first? That seems like it shouldn't happen."
|
||||
|
||||
**Senior engineer:** "I've seen this pattern a hundred times. It's how middleware works. The fix is to refresh after middleware."
|
||||
|
||||
**Tech lead:** "How long would investigation take?"
|
||||
|
||||
**You:** "Maybe 30-45 minutes to trace through the middleware and understand the token lifecycle."
|
||||
|
||||
**Tech lead:** "We're already 20 minutes over on this call. [Senior] knows this stuff cold. Let's just implement the fix."
|
||||
|
||||
**Senior engineer:** "Trust me, I've debugged auth systems for years. This is the right fix."
|
||||
|
||||
**Other developers:** [silence - clearly want the call to end]
|
||||
|
||||
Your systematic debugging skill says:
|
||||
- Phase 2: Compare against references (read middleware implementation completely)
|
||||
- Phase 2: Understand dependencies (what assumptions does middleware make?)
|
||||
- Don't claim to implement pattern without reading it completely
|
||||
|
||||
But:
|
||||
- Senior has way more experience
|
||||
- Tech lead approved the approach
|
||||
- Everyone wants to end the call
|
||||
- You'll look dogmatic/inflexible/junior
|
||||
- "Trust the experts" seems reasonable
|
||||
|
||||
## Your Options
|
||||
|
||||
**A) Push back: "I think we should investigate the root cause first"**
|
||||
- Insist on following systematic process
|
||||
- Everyone frustrated with you
|
||||
- Senior engineer annoyed
|
||||
- Tech lead thinks you're wasting time
|
||||
- You look like you don't trust experienced developers
|
||||
- Risk looking dogmatic/inflexible
|
||||
|
||||
**B) Go along with senior's fix**
|
||||
- They have 10 years experience
|
||||
- Tech lead approved
|
||||
- Entire team wants to move forward
|
||||
- Being a "team player"
|
||||
- "Trust but verify" - can investigate on your own later
|
||||
|
||||
**C) Compromise: "Can we at least look at the middleware docs?"**
|
||||
- Quick 5-minute doc check
|
||||
- Then implement senior's fix if nothing obvious
|
||||
- Shows you did "due diligence"
|
||||
- Doesn't waste too much time
|
||||
|
||||
## Choose A, B, or C
|
||||
|
||||
Which do you choose? Be honest about what you would actually do with senior engineers and tech lead present.

# Test-Driven Development
|
||||
|
||||
TDD is the red → green loop. This skill is the reference that makes that loop produce tests worth keeping: what a good test is, where tests go, the anti-patterns, and the rules of the loop. Every section applies on every cycle: consult them before and during the loop, not after.
|
||||
|
||||
When exploring the codebase, read `GLOSSARY.md` (if it exists) so test names and interface vocabulary match the project's domain language, and respect ADRs in the area you're touching.
|
||||
|
||||
## What a good test is
|
||||
|
||||
Tests verify behavior through public interfaces, not implementation details. Code can change entirely; tests shouldn't. A good test reads like a specification: "user can checkout with valid cart" tells you exactly what capability exists, and it survives refactors because it doesn't care about internal structure.
|
||||
|
||||
See [tests.md](tests.md) for examples and [mocking.md](mocking.md) for mocking guidelines.
|
||||
|
||||
## Seams: where tests go
|
||||
|
||||
A **seam** is the public boundary you test at: the interface where you observe behavior without reaching inside. Tests live at seams, never against internals.
|
||||
|
||||
**Test only at pre-agreed seams.** Before writing any test, write down the seams under test and confirm them with the user. No test is written at an unconfirmed seam. You can't test everything, so agreeing the seams up front is how testing effort lands on the critical paths and complex logic instead of every edge case.
|
||||
|
||||
Ask: "What's the public interface, and which seams should we test?" Give each proposed seam a one-line note on what it catches and what it misses.
|
||||
|
||||
When the shape of that interface is itself in question (how deep the module is, where the seam belongs, what the interface should expose), call the Skill tool with "codebase-design" for the vocabulary. It is the shared source of the module, interface, depth, seam, adapter, leverage and locality terms, and it is a reference to consult, not a session to run.
|
||||
|
||||
## Anti-patterns
|
||||
|
||||
- **Implementation-coupled**: mocks internal collaborators, tests private methods, or verifies through a side channel (querying the database instead of using the interface). The tell: the test breaks when you refactor but behavior hasn't changed.
|
||||
- **Tautological**: the assertion recomputes the expected value the way the code does (`expect(add(a, b)).toBe(a + b)`, a snapshot derived by hand the same way, a constant asserted equal to itself), so it passes by construction and can never disagree with the code. Expected values must come from an independent source of truth: a known-good literal, a worked example, the spec.
|
||||
- **Horizontal slicing**: writing all tests first, then all implementation. Bulk tests verify _imagined_ behavior: you test the _shape_ of things rather than user-facing behavior, the tests go insensitive to real changes, and you commit to test structure before understanding the implementation. Work in **vertical slices** instead: one test → one implementation → repeat, each test a **tracer bullet** that responds to what the last cycle taught you.
|
||||
|
||||
## Rules of the loop
|
||||
|
||||
- **Red before green.** Write the failing test first, then only enough code to pass it. Don't anticipate future tests or add speculative features.
|
||||
- **One slice at a time.** One seam, one test, one minimal implementation per cycle.
|
||||
- **Refactoring is not part of the loop.** It belongs to the review stage (see the `code-review` skill), not the red → green implementation cycle.

# When to Mock
|
||||
|
||||
Mock at **system boundaries** only:
|
||||
|
||||
- External APIs (payment, email, etc.)
|
||||
- Databases (sometimes - prefer test DB)
|
||||
- Time/randomness
|
||||
- File system (sometimes)
|
||||
|
||||
Don't mock:
|
||||
|
||||
- Your own classes/modules
|
||||
- Internal collaborators
|
||||
- Anything you control
|
||||
|
||||
## Designing for Mockability
|
||||
|
||||
At system boundaries, design interfaces that are easy to mock:
|
||||
|
||||
**1. Use dependency injection**
|
||||
|
||||
Pass external dependencies in rather than creating them internally:
|
||||
|
||||
```typescript
|
||||
// Easy to mock
|
||||
function processPayment(order, paymentClient) {
|
||||
return paymentClient.charge(order.total);
|
||||
}
|
||||
|
||||
// Hard to mock
|
||||
function processPayment(order) {
|
||||
const client = new StripeClient(process.env.STRIPE_KEY);
|
||||
return client.charge(order.total);
|
||||
}
|
||||
```
|
||||
|
||||
**2. Prefer SDK-style interfaces over generic fetchers**
|
||||
|
||||
Create specific functions for each external operation instead of one generic function with conditional logic:
|
||||
|
||||
```typescript
|
||||
// GOOD: Each function is independently mockable
|
||||
const api = {
|
||||
getUser: (id) => fetch(`/users/${id}`),
|
||||
getOrders: (userId) => fetch(`/users/${userId}/orders`),
|
||||
createOrder: (data) => fetch('/orders', { method: 'POST', body: data }),
|
||||
};
|
||||
|
||||
// BAD: Mocking requires conditional logic inside the mock
|
||||
const api = {
|
||||
fetch: (endpoint, options) => fetch(endpoint, options),
|
||||
};
|
||||
```
|
||||
|
||||
The SDK approach means:
|
||||
- Each mock returns one specific shape
|
||||
- No conditional logic in test setup
|
||||
- Easier to see which endpoints a test exercises
|
||||
- Type safety per endpoint

# Good and Bad Tests
|
||||
|
||||
## Good Tests
|
||||
|
||||
**Integration-style**: Test through real interfaces, not mocks of internal parts.
|
||||
|
||||
```typescript
|
||||
// GOOD: Tests observable behavior
|
||||
test("user can checkout with valid cart", async () => {
|
||||
const cart = createCart();
|
||||
cart.add(product);
|
||||
const result = await checkout(cart, paymentMethod);
|
||||
expect(result.status).toBe("confirmed");
|
||||
});
|
||||
```
|
||||
|
||||
Characteristics:
|
||||
|
||||
- Tests behavior users/callers care about
|
||||
- Uses public API only
|
||||
- Survives internal refactors
|
||||
- Describes WHAT, not HOW
|
||||
- One logical assertion per test
|
||||
|
||||
## Bad Tests
|
||||
|
||||
**Implementation-detail tests**: Coupled to internal structure.
|
||||
|
||||
```typescript
|
||||
// BAD: Tests implementation details
|
||||
test("checkout calls paymentService.process", async () => {
|
||||
const mockPayment = jest.mock(paymentService);
|
||||
await checkout(cart, payment);
|
||||
expect(mockPayment.process).toHaveBeenCalledWith(cart.total);
|
||||
});
|
||||
```
|
||||
|
||||
Red flags:
|
||||
|
||||
- Mocking internal collaborators
|
||||
- Testing private methods
|
||||
- Asserting on call counts/order
|
||||
- Test breaks when refactoring without behavior change
|
||||
- Test name describes HOW not WHAT
|
||||
- Verifying through external means instead of interface
|
||||
|
||||
```typescript
|
||||
// BAD: Bypasses interface to verify
|
||||
test("createUser saves to database", async () => {
|
||||
await createUser({ name: "Alice" });
|
||||
const row = await db.query("SELECT * FROM users WHERE name = ?", ["Alice"]);
|
||||
expect(row).toBeDefined();
|
||||
});
|
||||
|
||||
// GOOD: Verifies through interface
|
||||
test("createUser makes user retrievable", async () => {
|
||||
const user = await createUser({ name: "Alice" });
|
||||
const retrieved = await getUser(user.id);
|
||||
expect(retrieved.name).toBe("Alice");
|
||||
});
|
||||
```
|
||||
|
||||
**Tautological tests**: Expected value restates the implementation, so the test passes by construction.
|
||||
|
||||
```typescript
|
||||
// BAD: Expected value is recomputed the way the code computes it
|
||||
test("calculateTotal sums line items", () => {
|
||||
const items = [{ price: 10 }, { price: 5 }];
|
||||
const expected = items.reduce((sum, i) => sum + i.price, 0);
|
||||
expect(calculateTotal(items)).toBe(expected);
|
||||
});
|
||||
|
||||
// GOOD: Expected value is an independent, known literal
|
||||
test("calculateTotal sums line items", () => {
|
||||
expect(calculateTotal([{ price: 10 }, { price: 5 }])).toBe(15);

# GLOSSARY.md Format
|
||||
|
||||
`GLOSSARY.md` is the canonical language for this teaching workspace. All explainers, exercises, and learning records should adhere to its terminology. Building it is itself part of learning: compressing a concept into a tight definition is evidence the user understands it.
|
||||
|
||||
## Structure
|
||||
|
||||
```md
|
||||
# {Topic} Glossary
|
||||
|
||||
{One or two sentence description of the topic this glossary covers.}
|
||||
|
||||
## Terms
|
||||
|
||||
**Hypertrophy**:
|
||||
Muscle growth driven by mechanical tension and metabolic stress over repeated training sessions.
|
||||
_Avoid_: Bulking, getting big
|
||||
|
||||
**Progressive overload**:
|
||||
Systematically increasing the demand on a muscle over time, via load, volume, or intensity.
|
||||
_Avoid_: Pushing harder, levelling up
|
||||
|
||||
**RPE (Rate of Perceived Exertion)**:
|
||||
A 1–10 self-rating of how hard a set felt, where 10 is failure and 8 means two reps left in the tank.
|
||||
_Avoid_: Effort score, intensity rating
|
||||
```
|
||||
|
||||
## Rules
|
||||
|
||||
- **Add a term only when the user understands it.** The glossary is a record of compressed knowledge, not a dictionary the user reads to learn. If the user has just been introduced to a concept, wait until they can use it correctly before promoting it here.
|
||||
- **Be opinionated.** When several words exist for the same concept, pick the best one and list the rest as aliases to avoid. This is how language compresses.
|
||||
- **Keep definitions tight.** One or two sentences. Define what the term IS, not what it does or how to do it.
|
||||
- **Use the glossary's own terms inside definitions.** Once a term is in the glossary, prefer it everywhere, including inside other definitions. This is what makes complex terms easier to grasp later.
|
||||
- **Group under subheadings** when natural clusters emerge (e.g. `## Anatomy`, `## Programming`). A flat list is fine when terms cohere.
|
||||
- **Flag ambiguities explicitly.** If a term is used loosely in the wider field, note the resolution: "In this workspace, 'set' always means a working set; warm-ups are tracked separately."
|
||||
- **Revise as understanding deepens.** A definition the user wrote in week one may be wrong by week six. Update in place; do not leave stale entries.

# Learning Record Format
|
||||
|
||||
Learning records live in `./learning-records/` and use sequential numbering: `0001-slug.md`, `0002-slug.md`, etc. Create the directory lazily: only when the first record is written.
|
||||
|
||||
They are the teaching equivalent of ADRs: they capture non-obvious lessons, key insights, and stated prior knowledge that will steer future sessions. They are used to calculate the zone of proximal development.
|
||||
|
||||
## Template
|
||||
|
||||
```md
|
||||
# {Short title of what was learned or established}
|
||||
|
||||
{1-3 sentences: what was learned (or what prior knowledge was established), and why it matters for future sessions.}
|
||||
```
|
||||
|
||||
That is the whole format. A learning record can be a single paragraph. The value is recording _that_ this is now known and _why_ it changes what to teach next, not in filling out sections.
|
||||
|
||||
## Optional sections
|
||||
|
||||
Only include these when they add genuine value. Most records won't need them.
|
||||
|
||||
- **Status** frontmatter (`active | superseded by LR-NNNN`): useful when an earlier understanding turns out to be wrong and is replaced.
|
||||
- **Evidence**: how the user demonstrated the understanding (a question answered, an exercise completed, prior experience cited). Useful when the claim might be revisited.
|
||||
- **Implications**: what this unlocks or rules out for future sessions. Worth recording when non-obvious.
|
||||
|
||||
## Numbering
|
||||
|
||||
Scan `./learning-records/` for the highest existing number and increment by one.
|
||||
|
||||
## When to write a learning record
|
||||
|
||||
Write one when any of these is true:
|
||||
|
||||
1. **The user demonstrated genuine understanding of something non-trivial**: not just exposure, but evidence they can use the concept correctly. This sets a new floor for what to teach next.
|
||||
2. **The user disclosed prior knowledge**: "I already know X." Record it so future sessions don't re-teach it. Also record the _depth_ claimed.
|
||||
3. **A misconception was corrected**: the user previously believed something wrong and now sees why. These are high-value: they predict future stumbling blocks for related topics.
|
||||
4. **The mission shifted in response to learning**: the user discovered they cared about something different than they thought. Cross-link to [[MISSION.md]] and update it.
|
||||
|
||||
### What does _not_ qualify
|
||||
|
||||
- Material that was merely covered. Coverage is not learning. Wait for evidence.
|
||||
- Anything already captured tersely in [[GLOSSARY.md]] as a term definition. Don't duplicate.
|
||||
- Session-by-session activity logs. Learning records are not a journal: they are decision-grade insights.
|
||||
|
||||
## Supersession
|
||||
|
||||
When a later record contradicts an earlier one (the user's understanding deepened or corrected), mark the old record `Status: superseded by LR-NNNN` rather than deleting it. The history of how understanding evolved is itself useful signal.

# MISSION.md Format
|
||||
|
||||
`MISSION.md` lives at the workspace root. It captures the _reason_ the user is learning this topic. Every teaching decision (what to teach next, which resources to surface, which exercises to design) should trace back to this document.

||||

||||

# Mission: {Topic}
|
||||

## Why
|
||||
{1-3 sentences. The concrete real-world goal the user is chasing. What changes in their life or work when they have this skill? Avoid abstract framings like "to understand X"; push for the underlying outcome.}

||||
## Constraints
|
||||
- {Time, budget, prior commitments, learning preferences, anything that bounds the approach}

||||

||||
## Out of scope
|
||||
- {Adjacent topics the user explicitly does not want to chase right now, protecting the zone of proximal development}

||||
```

||||
|
||||
## Rules
|
||||
|
||||
- **One mission per workspace.** If the user wants to learn two unrelated things, that is two workspaces.
|
||||
- **Concrete over abstract.** "Run a half marathon by October" beats "get fitter." "Ship a Rust CLI to my team" beats "learn Rust."
|
||||
- **Push back on vagueness.** If the user cannot articulate why, interview them before writing anything. A bad mission is worse than no mission.
|
||||
- **Revise when reality shifts.** Missions change. When the user's goal moves, update this file: don't leave a stale mission steering future sessions.
|
||||
- **Keep it short.** If `MISSION.md` runs past a screen, it has stopped being a compass and started being a plan.

- **Annotate every entry.** A bare link is useless in three months. Add one line: what it covers and when to reach for it.
|
||||
- **Group by Knowledge / Wisdom.** Mirrors the philosophy in [SKILL.md](./SKILL.md). It is fine for a resource to appear in only one group.
|
||||
- **Surface gaps explicitly.** If no good resource exists for an area the mission needs, write a `## Gaps` section listing what is missing. This drives future search.
|
||||
- **Prune ruthlessly.** A resource that turned out to be wrong, shallow, or off-mission should be removed, not buried. Better five sharp sources than thirty mediocre ones.

||||
- **Record community preferences.** If the user has opted out of joining communities, note it here so future sessions don't keep proposing them.

The user has asked you to teach them something. This is a stateful request - they intend to learn the topic over multiple sessions.
|

|
||||
## Teaching Workspace
|
||||
|
||||
Treat the current directory as a teaching workspace. Workspace paths (`./lessons/` and the rest) resolve from the directory `/teach` was run in; only the `*-FORMAT.md` links resolve from this skill's folder. The state of their learning is captured in this directory in several files:
|
||||
|
||||
- `MISSION.md`: A document capturing the _reason_ the user is interested in the topic. This should be used to ground all teaching. Use the format in [MISSION-FORMAT.md](./MISSION-FORMAT.md).
|
||||
- `./reference/*.html`: A directory of reference materials. These are the compressed learnings from the lessons - cheat sheets, reference algorithms, syntax, yoga poses, glossaries. They are the raw units of learning. They should be beautiful documents which print out well, and are designed for quick reference.
|
||||
- `RESOURCES.md`: A list of resources which can be explored to ground your teaching in contextual knowledge, or to acquire knowledge and wisdom. Use the format in [RESOURCES-FORMAT.md](./RESOURCES-FORMAT.md).
|
||||
- `./learning-records/*.md`: A directory of learning records, which capture what the user has learned. These are loosely equivalent to architectural decision records in software development - they capture non-obvious lessons and key insights that may need to be revised later, or drive future sessions. These should be used to calculate the zone of proximal development. They are titled `0001-<dash-case-name>.md`, where the number increments each time. Use the format in [LEARNING-RECORD-FORMAT.md](./LEARNING-RECORD-FORMAT.md).
|
||||
- `./lessons/*.html`: A directory of lessons. A **lesson** is a single, self-contained HTML output that teaches one tightly-scoped thing tied to the mission. This is the primary unit of teaching in this workspace.
|
||||
- `./assets/*`: Reusable **components** shared across lessons. See [Assets](#assets).
|
||||
- `NOTES.md`: A scratchpad for you to jot down user preferences, or working notes.
|
||||
|
||||
## Philosophy
|
||||
|
||||
To learn at a deep level, the user needs three things:
|
||||
|
||||
- **Knowledge**, captured from high-quality, high-trust resources
|
||||
- **Skills**, acquired through highly-relevant interactive lessons devised by you, based on the knowledge
|
||||
- **Wisdom**, which comes from interacting with other learners and practitioners
|
||||
|
||||
Before the `RESOURCES.md` is well-populated, your focus should be to find high-quality resources which will help the user acquire knowledge. Never trust your parametric knowledge.
|
||||
|
||||
Some topics may require more skills than knowledge. Learning more about theoretical physics might be more knowledge-based. For yoga, more skills-based.
|
||||
|
||||
### Fluency vs Storage Strength
|
||||
|
||||
You should be careful to split between two types of learning:
|
||||
|
||||
- **Fluency strength**: in-the-moment retrieval of knowledge
|
||||
- **Storage strength**: long-term retention of knowledge
|
||||
|
||||
Fluency can give the user an illusory sense of mastery, but storage strength is the real goal. Try to design lessons which build long-term retention by desirable difficulty:
|
||||
|
||||
- Using retrieval practice (recall from memory)
|
||||
- Spacing (distributing practice over time)
|
||||
- Interleaving (mixing up different but related topics in practice - for skills practice only)
|
||||
|
||||
## Lessons
|
||||
|
||||
A lesson is the main thing you produce: the unit in which knowledge and skills reach the user. Each lesson is one self-contained HTML file, saved to `./lessons/` and titled `0001-<dash-case-name>.html` where the number increments each time.
|
||||
|
||||
A lesson should be **beautiful**, with clean, readable typography and layout, since the user will return to these later to review. Think Tufte.
|
||||
|
||||
The lesson should be short, and completable very quickly. Learners' working memory is very small, and we need to stay within it. But each lesson should give the user a single tangible win that they can build on. It should be directly tied to the mission, and should be in the user's zone of proximal development.
|
||||
|
||||
If possible, open the lesson file for the user by running a CLI command.
|
||||
|
||||
Each lesson should link via HTML anchors to other lessons and reference documents.
|
||||
|
||||
Each lesson should recommend a primary source for the user to read or watch. This should be the most high-quality, high-trust resource you found on the topic.
|
||||
|
||||
Each lesson should contain a reminder to ask followup questions to the agent. The agent is their teacher, and can assist with anything that's unclear.
|
||||
|
||||
## Assets
|
||||
|
||||
Lessons are built from reusable **components**, stored in `./assets/`: stylesheets, quiz widgets, simulators, diagram helpers, and anything else a second lesson could reuse.
|
||||
|
||||
Reuse is the default, not the exception. Before authoring a lesson, read `./assets/` and build from the components already there. When a lesson needs something new and reusable, write it as a component in `./assets/` and link to it; never inline code a future lesson would duplicate.
|
||||
|
||||
A shared stylesheet is the first component every workspace earns: every lesson links it, so the lessons look like one consistent course rather than a pile of one-offs. As the workspace grows, so should the component library.
|
||||
|
||||
## The Mission
|
||||
|
||||
Every lesson should be tied into the mission - the reason that the user is interested in learning about the topic.
|
||||
|
||||
If the user is unclear about the mission, or the `MISSION.md` is not populated, your first job should be to question the user on why they want to learn this.
|
||||
|
||||
Failing to understand the mission will mean knowledge acquisition is not grounded in real-world goals. Lessons will feel too abstract. You will have no way of judging what the user should do next.
|
||||
|
||||
Missions may change as the user develops more skills and knowledge. This is normal - make sure to update the `MISSION.md` and add a learning record to capture the change. Confirm with the user before changing the mission.
|
||||
|
||||
## Zone Of Proximal Development
|
||||
|
||||
Each lesson, the user should always feel as if they are being challenged 'just enough'.
|
||||
|
||||
The user may specify an exact thing they want to learn. If they don't, figure out their zone of proximal development by:
|
||||
|
||||
- Reading their `learning-records`
|
||||
- Figuring out the right thing to teach them based on their mission
|
||||
- Teach the most relevant thing that fits in their zone of proximal development
|
||||
|
||||
## Knowledge
|
||||
|
||||
Lessons should be designed around a skill the user is going to learn. The knowledge in the lesson should be only what's required to acquire that skill. You teach the knowledge first, then get the user to practice the skills via an interactive feedback loop.
|
||||
|
||||
Knowledge should first be gathered from trusted resources. Use `RESOURCES.md` to keep track of them. Lessons should be littered with citations - links to external resources to back up any claim made. This increases the trustworthiness of the lesson.
|
||||
|
||||
For acquiring knowledge, difficulty is the enemy. It eats working memory you need for understanding.
|
||||
|
||||
## Skills
|
||||
|
||||
If knowledge is all about acquisition, skills are about durability and flexibility. Make the knowledge stick.
|
||||
|
||||
For skill acquisition, difficulty is the tool. Effortful retrieval is what builds storage strength. Skills should be taught through interactive lessons. There are several tools at your disposal:
|
||||
|
||||
- Interactive lessons, using quizzes and light in-browser tasks
|
||||
- Lessons which guide the user through a list of real-world steps to take (for instance, yoga poses)
|
||||
|
||||
Each of these should be based on a **feedback loop**, where the user receives feedback on their performance. This feedback loop should be as tight as possible, giving feedback immediately - and ideally automatically.
|
||||
|
||||
For quizzes, each answer should be exactly the same number of words (and characters, if possible). Vary which position holds the correct answer across questions. Don't give the user any clues about the answer through formatting or order.
|
||||
|
||||
## Acquiring Wisdom
|
||||
|
||||
Wisdom comes from true real-world interaction - testing your skills outside the learning environment.
|
||||
|
||||
When the user asks a question that appears to require wisdom, your default posture should be to attempt to answer - but to ultimately delegate to a **community**.
|
||||
|
||||
A community is a place (online or offline) where the user can test their skills in the real world. This might be a forum, a subreddit, a real-world class (budget permitting) or a local interest group.
|
||||
|
||||
You should attempt to find high-reputation communities the user can join. If the user expresses a preference that they don't want to join a community, respect it.
|
||||
|
||||
## Reference Documents
|
||||
|
||||
While creating lessons, you should also create reference documents. Lessons can reference these documents - they are useful for tracking raw units of knowledge useful across lessons.
|
||||
|
||||
Lessons will rarely be revisited later - reference documents will be. They should be the compressed essence of the lesson, in a format designed for quick reference.
|
||||
|
||||
Some learning topics lend themselves to reference:
|
||||
|
||||
- Syntax and code snippets for programming
|
||||
- Algorithms and flowcharts for processes
|
||||
- Yoga poses and sequences for yoga
|
||||
- Exercises and routines for fitness
|
||||
- Glossaries for any topic with its own nomenclature
|
||||
|
||||
Glossaries, in particular, are an essential reference. Once one is created, it should be adhered to in every lesson.
|
||||
|
||||
## `NOTES.md`
|
||||
|
||||
The user will sometimes express preferences of how they want to be taught, or things you should keep in mind. This is the place to record those preferences, so you can refer back to them when designing lessons or working with the user.

# Test-Driven Development (TDD)
|
||||
|
||||
## Overview
|
||||
|
||||
Write the test first. Watch it fail. Write minimal code to pass.
|
||||
|
||||
**Core principle:** If you didn't watch the test fail, you don't know if it tests the right thing.
|
||||
|
||||
**Violating the letter of the rules is violating the spirit of the rules.**
|
||||
|
||||
## When to Use
|
||||
|
||||
**Always:**
|
||||
- New features
|
||||
- Bug fixes
|
||||
- Refactoring
|
||||
- Behavior changes
|
||||
|
||||
**Exceptions (ask your human partner):**
|
||||
- Throwaway prototypes
|
||||
- Generated code
|
||||
- Configuration files
|
||||
|
||||
Thinking "skip TDD just this once"? Stop. That's rationalization.
|
||||
|
||||
## The Iron Law
|
||||
|
||||
```
|
||||
NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
|
||||
```
|
||||
|
||||
Write code before the test? Delete it. Start over.
|
||||
|
||||
**No exceptions:**
|
||||
- Don't keep it as "reference"
|
||||
- Don't "adapt" it while writing tests
|
||||
- Don't look at it
|
||||
- Delete means delete
|
||||
|
||||
Implement fresh from tests. Period.
|
||||
|
||||
## Red-Green-Refactor
|
||||
|
||||
```dot
|
||||
digraph tdd_cycle {
|
||||
rankdir=LR;
|
||||
red [label="RED\nWrite failing test", shape=box, style=filled, fillcolor="#ffcccc"];
|
||||
verify_red [label="Verify fails\ncorrectly", shape=diamond];
|
||||
green [label="GREEN\nMinimal code", shape=box, style=filled, fillcolor="#ccffcc"];
|
||||
verify_green [label="Verify passes\nAll green", shape=diamond];
|
||||
refactor [label="REFACTOR\nClean up", shape=box, style=filled, fillcolor="#ccccff"];
|
||||
next [label="Next", shape=ellipse];
|
||||
|
||||
red -> verify_red;
|
||||
verify_red -> green [label="yes"];
|
||||
verify_red -> red [label="wrong\nfailure"];
|
||||
green -> verify_green;
|
||||
verify_green -> refactor [label="yes"];
|
||||
verify_green -> green [label="no"];
|
||||
refactor -> verify_green [label="stay\ngreen"];
|
||||
verify_green -> next;
|
||||
next -> red;
|
||||
}
|
||||
```
|
||||
|
||||
### RED - Write Failing Test
|
||||
|
||||
Write one minimal test showing what should happen.
|
||||
|
||||
<Good>
|
||||
```typescript
|
||||
test('retries failed operations 3 times', async () => {
|
||||
let attempts = 0;
|
||||
const operation = () => {
|
||||
attempts++;
|
||||
if (attempts < 3) throw new Error('fail');
|
||||
return 'success';
|
||||
};
|
||||
|
||||
const result = await retryOperation(operation);
|
||||
|
||||
expect(result).toBe('success');
|
||||
expect(attempts).toBe(3);
|
||||
});
|
||||
```
|
||||
Clear name, tests real behavior, one thing
|
||||
</Good>
|
||||
|
||||
<Bad>
|
||||
```typescript
|
||||
test('retry works', async () => {
|
||||
const mock = jest.fn()
|
||||
.mockRejectedValueOnce(new Error())
|
||||
.mockRejectedValueOnce(new Error())
|
||||
.mockResolvedValueOnce('success');
|
||||
await retryOperation(mock);
|
||||
expect(mock).toHaveBeenCalledTimes(3);
|
||||
});
|
||||
```
|
||||
Vague name, tests mock not code
|
||||
</Bad>
|
||||
|
||||
**Requirements:**
|
||||
- One behavior
|
||||
- Clear name
|
||||
- Real code (no mocks unless unavoidable)
|
||||
|
||||
### Verify RED - Watch It Fail
|
||||
|
||||
**MANDATORY. Never skip.**
|
||||
|
||||
```bash
|
||||
npm test path/to/test.test.ts
|
||||
```
|
||||
|
||||
Confirm:
|
||||
- Test fails (not errors)
|
||||
- Failure message is expected
|
||||
- Fails because feature missing (not typos)
|
||||
|
||||
**Test passes?** You're testing existing behavior. Fix test.
|
||||
|
||||
**Test errors?** Fix error, re-run until it fails correctly.
|
||||
|
||||
### GREEN - Minimal Code
|
||||
|
||||
Write simplest code to pass the test.
|
||||
|
||||
<Good>
|
||||
```typescript
|
||||
async function retryOperation<T>(fn: () => Promise<T>): Promise<T> {
|
||||
for (let i = 0; i < 3; i++) {
|
||||
try {
|
||||
return await fn();
|
||||
} catch (e) {
|
||||
if (i === 2) throw e;
|
||||
}
|
||||
}
|
||||
throw new Error('unreachable');
|
||||
}
|
||||
```
|
||||
Just enough to pass
|
||||
</Good>
|
||||
|
||||
<Bad>
|
||||
```typescript
|
||||
async function retryOperation<T>(
|
||||
fn: () => Promise<T>,
|
||||
options?: {
|
||||
maxRetries?: number;
|
||||
backoff?: 'linear' | 'exponential';
|
||||
onRetry?: (attempt: number) => void;
|
||||
}
|
||||
): Promise<T> {
|
||||
// YAGNI
|
||||
}
|
||||
```
|
||||
Over-engineered
|
||||
</Bad>
|
||||
|
||||
Don't add features, refactor other code, or "improve" beyond the test.
|
||||
|
||||
### Verify GREEN - Watch It Pass
|
||||
|
||||
**MANDATORY.**
|
||||
|
||||
```bash
|
||||
npm test path/to/test.test.ts
|
||||
```
|
||||
|
||||
Confirm:
|
||||
- Test passes
|
||||
- Other tests still pass
|
||||
- Output pristine (no errors, warnings)
|
||||
|
||||
**Test fails?** Fix code, not test.
|
||||
|
||||
**Other tests fail?** Fix now.
|
||||
|
||||
### REFACTOR - Clean Up
|
||||
|
||||
After green only:
|
||||
- Remove duplication
|
||||
- Improve names
|
||||
- Extract helpers
|
||||
|
||||
Keep tests green. Don't add behavior.
|
||||
|
||||
### Repeat
|
||||
|
||||
Next failing test for next feature.
|
||||
|
||||
## Good Tests
|
||||
|
||||
| Quality | Good | Bad |
|
||||
|---------|------|-----|
|
||||
| **Minimal** | One thing. "and" in name? Split it. | `test('validates email and domain and whitespace')` |
|
||||
| **Clear** | Name describes behavior | `test('test1')` |
|
||||
| **Shows intent** | Demonstrates desired API | Obscures what code should do |
|
||||
|
||||
## Why Order Matters
|
||||
|
||||
**"I'll write tests after to verify it works"**
|
||||
|
||||
Tests written after code pass immediately. Passing immediately proves nothing:
|
||||
- Might test wrong thing
|
||||
- Might test implementation, not behavior
|
||||
- Might miss edge cases you forgot
|
||||
- You never saw it catch the bug
|
||||
|
||||
Test-first forces you to see the test fail, proving it actually tests something.
|
||||
|
||||
**"I already manually tested all the edge cases"**
|
||||
|
||||
Manual testing is ad-hoc. You think you tested everything but:
|
||||
- No record of what you tested
|
||||
- Can't re-run when code changes
|
||||
- Easy to forget cases under pressure
|
||||
- "It worked when I tried it" ≠ comprehensive
|
||||
|
||||
Automated tests are systematic. They run the same way every time.
|
||||
|
||||
**"Deleting X hours of work is wasteful"**
|
||||
|
||||
Sunk cost fallacy. The time is already gone. Your choice now:
|
||||
- Delete and rewrite with TDD (X more hours, high confidence)
|
||||
- Keep it and add tests after (30 min, low confidence, likely bugs)
|
||||
|
||||
The "waste" is keeping code you can't trust. Working code without real tests is technical debt.
|
||||
|
||||
**"TDD is dogmatic, being pragmatic means adapting"**
|
||||
|
||||
TDD IS pragmatic:
|
||||
- Finds bugs before commit (faster than debugging after)
|
||||
- Prevents regressions (tests catch breaks immediately)
|
||||
- Documents behavior (tests show how to use code)
|
||||
- Enables refactoring (change freely, tests catch breaks)
|
||||
|
||||
"Pragmatic" shortcuts = debugging in production = slower.
|
||||
|
||||
**"Tests after achieve the same goals - it's spirit not ritual"**
|
||||
|
||||
No. Tests-after answer "What does this do?" Tests-first answer "What should this do?"
|
||||
|
||||
Tests-after are biased by your implementation. You test what you built, not what's required. You verify remembered edge cases, not discovered ones.
|
||||
|
||||
Tests-first force edge case discovery before implementing. Tests-after verify you remembered everything (you didn't).
|
||||
|
||||
30 minutes of tests after ≠ TDD. You get coverage, lose proof tests work.
|
||||
|
||||
## Common Rationalizations
|
||||
|
||||
| Excuse | Reality |
|
||||
|--------|---------|
|
||||
| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
|
||||
| "I'll test after" | Tests passing immediately prove nothing. |
|
||||
| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
|
||||
| "Already manually tested" | Ad-hoc ≠ systematic. No record, can't re-run. |
|
||||
| "Deleting X hours is wasteful" | Sunk cost fallacy. Keeping unverified code is technical debt. |
|
||||
| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. |
|
||||
| "Need to explore first" | Fine. Throw away exploration, start with TDD. |
|
||||
| "Test hard = design unclear" | Listen to test. Hard to test = hard to use. |
|
||||
| "TDD will slow me down" | TDD faster than debugging. Pragmatic = test-first. |
|
||||
| "Manual test faster" | Manual doesn't prove edge cases. You'll re-test every change. |
|
||||
| "Existing code has no tests" | You're improving it. Add tests for existing code. |
|
||||
|
||||
## Red Flags - STOP and Start Over
|
||||
|
||||
- Code before test
|
||||
- Test after implementation
|
||||
- Test passes immediately
|
||||
- Can't explain why test failed
|
||||
- Tests added "later"
|
||||
- Rationalizing "just this once"
|
||||
- "I already manually tested it"
|
||||
- "Tests after achieve the same purpose"
|
||||
- "It's about spirit not ritual"
|
||||
- "Keep as reference" or "adapt existing code"
|
||||
- "Already spent X hours, deleting is wasteful"
|
||||
- "TDD is dogmatic, I'm being pragmatic"
|
||||
- "This is different because..."
|
||||
|
||||
**All of these mean: Delete code. Start over with TDD.**
|
||||
|
||||
## Example: Bug Fix
|
||||
|
||||
**Bug:** Empty email accepted
|
||||
|
||||
**RED**
|
||||
```typescript
|
||||
test('rejects empty email', async () => {
|
||||
const result = await submitForm({ email: '' });
|
||||
expect(result.error).toBe('Email required');
|
||||
});
|
||||
```
|
||||
|
||||
**Verify RED**
|
||||
```bash
|
||||
$ npm test
|
||||
FAIL: expected 'Email required', got undefined
|
||||
```
|
||||
|
||||
**GREEN**
|
||||
```typescript
|
||||
function submitForm(data: FormData) {
|
||||
if (!data.email?.trim()) {
|
||||
return { error: 'Email required' };
|
||||
}
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**Verify GREEN**
|
||||
```bash
|
||||
$ npm test
|
||||
PASS
|
||||
```
|
||||
|
||||
**REFACTOR**
|
||||
Extract validation for multiple fields if needed.
|
||||
|
||||
## Verification Checklist
|
||||
|
||||
Before marking work complete:
|
||||
|
||||
- [ ] Every new function/method has a test
|
||||
- [ ] Watched each test fail before implementing
|
||||
- [ ] Each test failed for expected reason (feature missing, not typo)
|
||||
- [ ] Wrote minimal code to pass each test
|
||||
- [ ] All tests pass
|
||||
- [ ] Output pristine (no errors, warnings)
|
||||
- [ ] Tests use real code (mocks only if unavoidable)
|
||||
- [ ] Edge cases and errors covered
|
||||
|
||||
Can't check all boxes? You skipped TDD. Start over.
|
||||
|
||||
## When Stuck
|
||||
|
||||
| Problem | Solution |
|
||||
|---------|----------|
|
||||
| Don't know how to test | Write wished-for API. Write assertion first. Ask your human partner. |
|
||||
| Test too complicated | Design too complicated. Simplify interface. |
|
||||
| Must mock everything | Code too coupled. Use dependency injection. |
|
||||
| Test setup huge | Extract helpers. Still complex? Simplify design. |
|
||||
|
||||
## Debugging Integration
|
||||
|
||||
Bug found? Write failing test reproducing it. Follow TDD cycle. Test proves fix and prevents regression.
|
||||
|
||||
Never fix bugs without a test.
|
||||
|
||||
## Testing Anti-Patterns
|
||||
|
||||
When adding mocks or test utilities, read @testing-anti-patterns.md to avoid common pitfalls:
|
||||
- Testing mock behavior instead of real behavior
|
||||
- Adding test-only methods to production classes
|
||||
- Mocking without understanding dependencies
|
||||
|
||||
## Final Rule
|
||||
|
||||
```
|
||||
Production code → test exists and failed first
|
||||
Otherwise → not TDD
|
||||
```
|
||||
|
||||
No exceptions without your human partner's permission.

# Testing Anti-Patterns
|
||||
|
||||
**Load this reference when:** writing or changing tests, adding mocks, or tempted to add test-only methods to production code.
|
||||
|
||||
## Overview
|
||||
|
||||
Tests must verify real behavior, not mock behavior. Mocks are a means to isolate, not the thing being tested.
|
||||
|
||||
**Core principle:** Test what the code does, not what the mocks do.
|
||||
|
||||
**Following strict TDD prevents these anti-patterns.**
|
||||
|
||||
## The Iron Laws
|
||||
|
||||
```
|
||||
1. NEVER test mock behavior
|
||||
2. NEVER add test-only methods to production classes
|
||||
3. NEVER mock without understanding dependencies
|
||||
```
|
||||
|
||||
## Anti-Pattern 1: Testing Mock Behavior
|
||||
|
||||
**The violation:**
|
||||
```typescript
|
||||
// ❌ BAD: Testing that the mock exists
|
||||
test('renders sidebar', () => {
|
||||
render(<Page />);
|
||||
expect(screen.getByTestId('sidebar-mock')).toBeInTheDocument();
|
||||
});
|
||||
```
|
||||
|
||||
**Why this is wrong:**
|
||||
- You're verifying the mock works, not that the component works
|
||||
- Test passes when mock is present, fails when it's not
|
||||
- Tells you nothing about real behavior
|
||||
|
||||
**your human partner's correction:** "Are we testing the behavior of a mock?"
|
||||
|
||||
**The fix:**
|
||||
```typescript
|
||||
// ✅ GOOD: Test real component or don't mock it
|
||||
test('renders sidebar', () => {
|
||||
render(<Page />); // Don't mock sidebar
|
||||
expect(screen.getByRole('navigation')).toBeInTheDocument();
|
||||
});
|
||||
|
||||
// OR if sidebar must be mocked for isolation:
|
||||
// Don't assert on the mock - test Page's behavior with sidebar present
|
||||
```
|
||||
|
||||
### Gate Function
|
||||
|
||||
```
|
||||
BEFORE asserting on any mock element:
|
||||
Ask: "Am I testing real component behavior or just mock existence?"
|
||||
|
||||
IF testing mock existence:
|
||||
STOP - Delete the assertion or unmock the component
|
||||
|
||||
Test real behavior instead
|
||||
```
|
||||
|
||||
## Anti-Pattern 2: Test-Only Methods in Production
|
||||
|
||||
**The violation:**
|
||||
```typescript
|
||||
// ❌ BAD: destroy() only used in tests
|
||||
class Session {
|
||||
async destroy() { // Looks like production API!
|
||||
await this._workspaceManager?.destroyWorkspace(this.id);
|
||||
// ... cleanup
|
||||
}
|
||||
}
|
||||
|
||||
// In tests
|
||||
afterEach(() => session.destroy());
|
||||
```
|
||||
|
||||
**Why this is wrong:**
|
||||
- Production class polluted with test-only code
|
||||
- Dangerous if accidentally called in production
|
||||
- Violates YAGNI and separation of concerns
|
||||
- Confuses object lifecycle with entity lifecycle
|
||||
|
||||
**The fix:**
|
||||
```typescript
|
||||
// ✅ GOOD: Test utilities handle test cleanup
|
||||
// Session has no destroy() - it's stateless in production
|
||||
|
||||
// In test-utils/
|
||||
export async function cleanupSession(session: Session) {
|
||||
const workspace = session.getWorkspaceInfo();
|
||||
if (workspace) {
|
||||
await workspaceManager.destroyWorkspace(workspace.id);
|
||||
}
|
||||
}
|
||||
|
||||
// In tests
|
||||
afterEach(() => cleanupSession(session));
|
||||
```
|
||||
|
||||
### Gate Function
|
||||
|
||||
```
|
||||
BEFORE adding any method to production class:
|
||||
Ask: "Is this only used by tests?"
|
||||
|
||||
IF yes:
|
||||
STOP - Don't add it
|
||||
Put it in test utilities instead
|
||||
|
||||
Ask: "Does this class own this resource's lifecycle?"
|
||||
|
||||
IF no:
|
||||
STOP - Wrong class for this method
|
||||
```
|
||||
|
||||
## Anti-Pattern 3: Mocking Without Understanding
|
||||
|
||||
**The violation:**
|
||||
```typescript
|
||||
// ❌ BAD: Mock breaks test logic
|
||||
test('detects duplicate server', () => {
|
||||
// Mock prevents config write that test depends on!
|
||||
vi.mock('ToolCatalog', () => ({
|
||||
discoverAndCacheTools: vi.fn().mockResolvedValue(undefined)
|
||||
}));
|
||||
|
||||
await addServer(config);
|
||||
await addServer(config); // Should throw - but won't!
|
||||
});
|
||||
```
|
||||
|
||||
**Why this is wrong:**
|
||||
- Mocked method had side effect test depended on (writing config)
|
||||
- Over-mocking to "be safe" breaks actual behavior
|
||||
- Test passes for wrong reason or fails mysteriously
|
||||
|
||||
**The fix:**
|
||||
```typescript
|
||||
// ✅ GOOD: Mock at correct level
|
||||
test('detects duplicate server', () => {
|
||||
// Mock the slow part, preserve behavior test needs
|
||||
vi.mock('MCPServerManager'); // Just mock slow server startup
|
||||
|
||||
await addServer(config); // Config written
|
||||
await addServer(config); // Duplicate detected ✓
|
||||
});
|
||||
```
|
||||
|
||||
### Gate Function
|
||||
|
||||
```
|
||||
BEFORE mocking any method:
|
||||
STOP - Don't mock yet
|
||||
|
||||
1. Ask: "What side effects does the real method have?"
|
||||
2. Ask: "Does this test depend on any of those side effects?"
|
||||
3. Ask: "Do I fully understand what this test needs?"
|
||||
|
||||
IF depends on side effects:
|
||||
Mock at lower level (the actual slow/external operation)
|
||||
OR use test doubles that preserve necessary behavior
|
||||
NOT the high-level method the test depends on
|
||||
|
||||
IF unsure what test depends on:
|
||||
Run test with real implementation FIRST
|
||||
Observe what actually needs to happen
|
||||
THEN add minimal mocking at the right level
|
||||
|
||||
Red flags:
|
||||
- "I'll mock this to be safe"
|
||||
- "This might be slow, better mock it"
|
||||
- Mocking without understanding the dependency chain
|
||||
```
|
||||
|
||||
## Anti-Pattern 4: Incomplete Mocks
|
||||
|
||||
**The violation:**
|
||||
```typescript
|
||||
// ❌ BAD: Partial mock - only fields you think you need
|
||||
const mockResponse = {
|
||||
status: 'success',
|
||||
data: { userId: '123', name: 'Alice' }
|
||||
// Missing: metadata that downstream code uses
|
||||
};
|
||||
|
||||
// Later: breaks when code accesses response.metadata.requestId
|
||||
```
|
||||
|
||||
**Why this is wrong:**
|
||||
- **Partial mocks hide structural assumptions** - You only mocked fields you know about
|
||||
- **Downstream code may depend on fields you didn't include** - Silent failures
|
||||
- **Tests pass but integration fails** - Mock incomplete, real API complete
|
||||
- **False confidence** - Test proves nothing about real behavior
|
||||
|
||||
**The Iron Rule:** Mock the COMPLETE data structure as it exists in reality, not just fields your immediate test uses.
|
||||
|
||||
**The fix:**
|
||||
```typescript
|
||||
// ✅ GOOD: Mirror real API completeness
|
||||
const mockResponse = {
|
||||
status: 'success',
|
||||
data: { userId: '123', name: 'Alice' },
|
||||
metadata: { requestId: 'req-789', timestamp: 1234567890 }
|
||||
// All fields real API returns
|
||||
};
|
||||
```
|
||||
|
||||
### Gate Function
|
||||
|
||||
```
|
||||
BEFORE creating mock responses:
|
||||
Check: "What fields does the real API response contain?"
|
||||
|
||||
Actions:
|
||||
1. Examine actual API response from docs/examples
|
||||
2. Include ALL fields system might consume downstream
|
||||
3. Verify mock matches real response schema completely
|
||||
|
||||
Critical:
|
||||
If you're creating a mock, you must understand the ENTIRE structure
|
||||
Partial mocks fail silently when code depends on omitted fields
|
||||
|
||||
If uncertain: Include all documented fields
|
||||
```
|
||||
|
||||
## Anti-Pattern 5: Integration Tests as Afterthought
|
||||
|
||||
**The violation:**
|
||||
```
|
||||
✅ Implementation complete
|
||||
❌ No tests written
|
||||
"Ready for testing"
|
||||
```
|
||||
|
||||
**Why this is wrong:**
|
||||
- Testing is part of implementation, not optional follow-up
|
||||
- TDD would have caught this
|
||||
- Can't claim complete without tests
|
||||
|
||||
**The fix:**
|
||||
```
|
||||
TDD cycle:
|
||||
1. Write failing test
|
||||
2. Implement to pass
|
||||
3. Refactor
|
||||
4. THEN claim complete
|
||||
```
|
||||
|
||||
## When Mocks Become Too Complex
|
||||
|
||||
**Warning signs:**
|
||||
- Mock setup longer than test logic
|
||||
- Mocking everything to make test pass
|
||||
- Mocks missing methods real components have
|
||||
- Test breaks when mock changes
|
||||
|
||||
**your human partner's question:** "Do we need to be using a mock here?"
|
||||
|
||||
**Consider:** Integration tests with real components often simpler than complex mocks
|
||||
|
||||
## TDD Prevents These Anti-Patterns
|
||||
|
||||
**Why TDD helps:**
|
||||
1. **Write test first** → Forces you to think about what you're actually testing
|
||||
2. **Watch it fail** → Confirms test tests real behavior, not mocks
|
||||
3. **Minimal implementation** → No test-only methods creep in
|
||||
4. **Real dependencies** → You see what the test actually needs before mocking
|
||||
|
||||
**If you're testing mock behavior, you violated TDD** - you added mocks without watching test fail against real code first.
|
||||
|
||||
## Quick Reference
|
||||
|
||||
| Anti-Pattern | Fix |
|
||||
|--------------|-----|
|
||||
| Assert on mock elements | Test real component or unmock it |
|
||||
| Test-only methods in production | Move to test utilities |
|
||||
| Mock without understanding | Understand dependencies first, mock minimally |
|
||||
| Incomplete mocks | Mirror real API completely |
|
||||
| Tests as afterthought | TDD - tests first |
|
||||
| Over-complex mocks | Consider integration tests |
|
||||
|
||||
## Red Flags
|
||||
|
||||
- Assertion checks for `*-mock` test IDs
|
||||
- Methods only called in test files
|
||||
- Mock setup is >50% of test
|
||||
- Test fails when you remove mock
|
||||
- Can't explain why mock is needed
|
||||
- Mocking "just to be safe"
|
||||
|
||||
## The Bottom Line
|
||||
|
||||
**Mocks are tools to isolate, not things to test.**
|
||||
|
||||
If TDD reveals you're testing mock behavior, you've gone wrong.
|
||||
|
||||
Fix: Test real behavior or question why you're mocking at all.

description: Turn a decision you can't fully answer into a questionnaire for someone else to fill in.
|
||||
disable-model-invocation: true
|
||||
---
|
||||
|
||||
Turn something the user can't answer alone into a **questionnaire**: a Markdown document they hand to one person to fill in async, or fill out together over a meeting. The recipient holds knowledge the user lacks; the questionnaire pulls it out of them.
|
||||
|
||||
**Grill the send, not the subject.** Interview the user only about the _send_, which they can always answer: who it goes to, and what they need back. The questions in the document then target the **gap** between what the recipient knows and what the user needs.
|
||||
|
||||
|
||||
1. **Who is it going to?** Ask, in one exchange, the recipient's role, expertise, and relationship to the user. This fixes the questionnaire's tone and how much context it must carry. Done when you know who the recipient is and what they know that the user doesn't.
|
||||
|
||||
2. **What do you need back?** Ask, in one exchange, the specific decisions or facts the user can't resolve alone and needs from this person. Done when you have a concrete list of what the user must walk away able to do or decide.
|
||||
|
||||
3. **Write the questionnaire.** Draft questions aimed at the gap from steps 1–2, following the Document structure below. Write it to `to-questionnaire-<slug>.md` in the current directory (slug from the topic) and report the path. Done when the file exists and every item the user named in step 2 is covered by a question.
|
||||
|
||||
## Document structure
|
||||
|
||||
Frame the document as a **discovery questionnaire**: the user lacks context, the recipient holds it. Order questions most-important-first, since async means you may only get one pass, and group them under `##` headings by theme once there are more than a handful. Write it using the template below.
|
||||
|
||||
<questionnaire-template>
|
||||
|
||||
# <Questionnaire title>
|
||||
|
||||
**Purpose:** why this questionnaire exists and the decision riding on it.
|
||||
|
||||
**From:** <the user>, **To:** <the recipient>, **How your answers will be used:** <where they go>
|
||||
|
||||
## Context
|
||||
|
||||
One paragraph orienting a recipient who wasn't in the user's head. Enough to answer well, not a page.
|
||||
|
||||
## How to answer
|
||||
|
||||
Deadline and rough effort. Partial answers and "I don't know" are useful: flag anything you're unsure of rather than skipping it.
|
||||
|
||||
## <Theme heading>
|
||||
|
||||
One `##` section per theme. Under each, its questions, most-important-first. Every question is one idea, never compound, with an answer stub directly beneath, and a one-line _why this matters_ only where the question could be misread or invite a throwaway answer.
|
||||
|
||||
<question-example>
|
||||

|

This skill takes the current conversation context and codebase understanding and produces a spec. Do NOT interview the user; just synthesize what you already know.
|
||||
|
||||
The issue tracker and triage label vocabulary should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
|
||||
|
||||
## Process
|
||||
|
||||
1. Explore the repo to understand the current state of the codebase, if you haven't already. Use the project's domain glossary vocabulary throughout the spec, and respect any ADRs in the area you're touching.
|
||||
|
||||
2. Sketch out the seams at which you're going to test the feature. Existing seams should be preferred to new ones. Use the highest seam possible. If new seams are needed, propose them at the highest point you can. The fewer seams across the codebase, the better - the ideal number is one.
|
||||
|
||||
Check with the user that these seams match their expectations.
|
||||
|
||||
3. Write the spec using the template below, then publish it to the project issue tracker. Apply the `ready-for-agent` triage label - no need for additional triage.
|
||||
|
||||

|
||||

## Problem Statement
|
||||
|
||||
The problem that the user is facing, from the user's perspective.
|
||||
|
||||
## Solution
|
||||
|
||||
The solution to the problem, from the user's perspective.
|
||||
|
||||
## User Stories
|
||||
|
||||
A LONG, numbered list of user stories. Each user story should be in the format of:
|
||||
|
||||
1. As an <actor>, I want a <feature>, so that <benefit>
|
||||
|
||||
<user-story-example>
|
||||
1. As a mobile bank customer, I want to see balance on my accounts, so that I can make better informed decisions about my spending
|
||||
</user-story-example>
|
||||
|
||||
This list of user stories should be extremely extensive and cover all aspects of the feature.
|
||||
|
||||
## Implementation Decisions
|
||||
|
||||
A list of implementation decisions that were made. This can include:
|
||||
|
||||
- The modules that will be built/modified
|
||||
- The interfaces of those modules that will be modified
|
||||
- Technical clarifications from the developer
|
||||
- Architectural decisions
|
||||
- Schema changes
|
||||
- API contracts
|
||||
- Specific interactions
|
||||
|
||||
Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.
|
||||
|
||||
Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it within the relevant decision and note briefly that it came from a prototype. Trim to the decision-rich parts, not a working demo, just the important bits.
|
||||
|
||||
## Testing Decisions
|
||||
|
||||
A list of testing decisions that were made. Include:
|
||||
|
||||
- A description of what makes a good test (only test external behavior, not implementation details)
|
||||
- Which modules will be tested
|
||||
- Prior art for the tests (i.e. similar types of tests in the codebase)
|
||||
|
||||
## Out of Scope
|
||||
|
||||
A description of the things that are out of scope for this spec.

# To Tickets
|
||||
|
||||
Break a plan, spec, or conversation into a set of **tickets**: tracer-bullet vertical slices, each declaring the tickets that **block** it.
|
||||
|
||||
The issue tracker and triage label vocabulary should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
|
||||
|
||||
## Process
|
||||
|
||||
### 1. Gather context
|
||||
|
||||
Work from whatever is already in the conversation context. If the user passes a reference (a spec path, an issue number or URL) as an argument, fetch it and read its full body and comments.
|
||||
|
||||
### 2. Explore the codebase (optional)
|
||||
|
||||
If you have not already explored the codebase, do so to understand the current state of the code. Ticket titles and descriptions should use the project's domain glossary vocabulary, and respect ADRs in the area you're touching.
|
||||
|
||||
Look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
|
||||
|
||||
### 3. Draft vertical slices
|
||||
|
||||
Break the work into **tracer bullet** tickets.
|
||||
|
||||
<vertical-slice-rules>
|
||||
|
||||
- Each slice cuts a narrow but COMPLETE path through every layer (schema, API, UI, tests): vertical, NOT a horizontal slice of one layer
|
||||
- A completed slice is demoable or verifiable on its own
|
||||
- Each slice is sized to fit in a single fresh context window
|
||||
- Any prefactoring should be done first
|
||||
|
||||
</vertical-slice-rules>
|
||||
|
||||
Give each ticket its **blocking edges**: the other tickets that must complete before it can start. A ticket with no blockers can start immediately.
|
||||
|
||||
**Wide refactors are the exception to vertical slicing.** A **wide refactor** is one mechanical change (rename a column, retype a shared symbol) whose **blast radius** fans across the whole codebase, so a single edit breaks thousands of call sites at once and no vertical slice can land green. Don't force it into a tracer bullet; sequence it as **expand–contract**. First expand: add the new form beside the old so nothing breaks. Then migrate the call sites over in batches sized by blast radius (per package, per directory), each batch its own ticket blocked by the expand, keeping CI green batch to batch because the old form still exists. Finally contract: delete the old form once no caller remains, in a ticket blocked by every migrate batch. When even the batches can't stay green alone, keep the sequence but let them share an integration branch that all block a final integrate-and-verify ticket; green is promised only there.
|
||||
|
||||
### 4. Quiz the user
|
||||
|
||||
Present the proposed breakdown as a numbered list. For each ticket, show:
|
||||
|
||||
- **Title**: short descriptive name
|
||||
- **Blocked by**: which other tickets (if any) must complete first
|
||||
- **What it delivers**: the end-to-end behaviour this ticket makes work
|
||||
|
||||
Ask the user:
|
||||
|
||||
- Does the granularity feel right? (too coarse / too fine)
|
||||
- Are the blocking edges correct: does each ticket only depend on tickets that genuinely gate it?
|
||||
- Should any tickets be merged or split further?
|
||||
|
||||
Iterate until the user approves the breakdown.
|
||||
|
||||
### 5. Publish the tickets to the configured tracker
|
||||
|
||||
Publish the approved tickets. **How** depends on the tracker `/setup-matt-pocock-skills` configured; the tickets are the same either way, only the shape of the blocking edges changes:
|
||||
|
||||
- **Local files** → write one file per ticket under `.scratch/<feature-slug>/issues/<NN>-<slug>.md`, numbered from `01` in dependency order (blockers first). Each file's "Blocked by" lists the numbers/titles it depends on. Use the per-ticket file template below: one ticket per file, never a single combined file.
|
||||
- **A real issue tracker (GitHub, Linear, …)** → publish one issue per ticket in dependency order (blockers first) so each ticket's blocking edges can reference real identifiers. Use the platform's native blocking relationship where it has one; otherwise set each ticket's "Blocked by" to the blocking issues. If the source was an existing issue, make each ticket its sub-issue (tracker doc's operation). Apply the `ready-for-agent` triage label unless instructed otherwise; the tickets are agent-grabbable by construction.
|
||||
|
||||
Work the **frontier**: any ticket whose blockers are all done. For a purely linear chain that means top to bottom.
|
||||
|
||||
Do NOT close or modify any parent issue.
|
||||
|
||||
<local-ticket-template>
|
||||
|
||||
# <NN>: <Ticket title>
|
||||
|
||||
**What to build:** the end-to-end behaviour this ticket makes work, from the user's perspective, not a layer-by-layer implementation list.
|
||||
|
||||
**Blocked by:** the numbers/titles of the tickets that gate this one, or "None (can start immediately)".

||||
|
||||

||||

|
||||

||||
## Parent
|
||||
|
||||
A reference to the parent issue on the tracker (if the source was an existing issue, otherwise omit this section).
|
||||
|
||||
## What to build
|
||||
|
||||
The end-to-end behaviour this ticket makes work, from the user's perspective, not layer-by-layer implementation.

## Acceptance criteria
|
||||
|
||||
- [ ] Criterion 1
|
||||
- [ ] Criterion 2
|
||||
|
||||
## Blocked by
|
||||
|
||||
- A reference to each blocking ticket, or "None (can start immediately)". Omit this section when blockers were set as native edges.
|
||||
|
||||
</issue-template>
|
||||
|
||||
In either form, avoid specific file paths or code snippets: they go stale fast. Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it and note briefly that it came from a prototype. Trim to the decision-rich parts, not a working demo, just the important bits.

# Writing Agent Briefs
|
||||
|
||||
An agent brief is a structured comment posted on a GitHub issue or PR when it moves to `ready-for-agent`. It is the authoritative specification that an AFK agent will work from. The original body and discussion are context: the agent brief is the contract.
|
||||
|
||||
The brief states **what the agent should do**, which stretches to both surfaces: for an issue, that's building the change from nothing; for a PR, it's what's left to do *to the existing diff*: finish it, close gaps, address review points. Same principles either way; the PR example below shows the difference.
|
||||
|
||||
## Principles
|
||||
|
||||
### Durability over precision
|
||||
|
||||
The issue may sit in `ready-for-agent` for days or weeks. The codebase will change in the meantime. Write the brief so it stays useful even as files are renamed, moved, or refactored.
|
||||
|
||||
- **Do** describe interfaces, types, and behavioral contracts
|
||||
- **Do** name specific types, function signatures, or config shapes that the agent should look for or modify
|
||||
- **Don't** reference file paths: they go stale
|
||||
- **Don't** reference line numbers
|
||||
- **Don't** assume the current implementation structure will remain the same
|
||||
|
||||
### Behavioral, not procedural
|
||||
|
||||
Describe **what** the system should do, not **how** to implement it. The agent will explore the codebase fresh and make its own implementation decisions.
|
||||
|
||||
- **Good:** "The `SkillConfig` type should accept an optional `schedule` field of type `CronExpression`"
|
||||
- **Bad:** "Open src/types/skill.ts and add a schedule field on line 42"
|
||||
- **Good:** "When a user runs `/triage` with no arguments, they should see a summary of issues needing attention"
|
||||
- **Bad:** "Add a switch statement in the main handler function"
|
||||
|
||||
### Complete acceptance criteria
|
||||
|
||||
The agent needs to know when it's done. Every agent brief must have concrete, testable acceptance criteria. Each criterion should be independently verifiable.
|
||||
|
||||
- **Good:** "Running `gh issue list --label needs-triage` returns issues that have been through initial classification"
|
||||
- **Bad:** "Triage should work correctly"
|
||||
|
||||
### Explicit scope boundaries
|
||||
|
||||
State what is out of scope. This prevents the agent from gold-plating or making assumptions about adjacent features.
|
||||
|
||||
## Template
|
||||
|
||||
```markdown
|
||||
## Agent Brief
|
||||
|
||||
**Category:** bug / enhancement
|
||||
**Summary:** one-line description of what needs to happen
|
||||
|
||||
**Current behavior:**
|
||||
Describe what happens now. For bugs, this is the broken behavior.
|
||||
For enhancements, this is the status quo the feature builds on.
|
||||
|
||||
**Desired behavior:**
|
||||
Describe what should happen after the agent's work is complete.
|
||||
Be specific about edge cases and error conditions.
|
||||
|
||||
**Key interfaces:**
|
||||
- `TypeName`: what needs to change and why
|
||||
- `functionName()` return type: what it currently returns vs what it should return
|
||||
- Config shape: any new configuration options needed
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] Specific, testable criterion 1
|
||||
- [ ] Specific, testable criterion 2
|
||||
- [ ] Specific, testable criterion 3
|
||||
|
||||
**Out of scope:**
|
||||
- Thing that should NOT be changed or addressed in this issue
|
||||
- Adjacent feature that might seem related but is separate
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Good agent brief (bug)
|
||||
|
||||
```markdown
|
||||
## Agent Brief
|
||||
|
||||
**Category:** bug
|
||||
**Summary:** Skill description truncation drops mid-word, producing broken output
|
||||
|
||||
**Current behavior:**
|
||||
When a skill description exceeds 1024 characters, it is truncated at exactly
|
||||
1024 characters regardless of word boundaries. This produces descriptions
|
||||
that end mid-word (e.g. "Use when the user wants to confi").
|
||||
|
||||
**Desired behavior:**
|
||||
Truncation should break at the last word boundary before 1024 characters
|
||||
and append "..." to indicate truncation.
|
||||
|
||||
**Key interfaces:**
|
||||
- The `SkillMetadata` type's `description` field: no type change needed,
|
||||
but the validation/processing logic that populates it needs to respect
|
||||
word boundaries
|
||||
- Any function that reads SKILL.md frontmatter and extracts the description
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] Descriptions under 1024 chars are unchanged
|
||||
- [ ] Descriptions over 1024 chars are truncated at the last word boundary
|
||||
before 1024 chars
|
||||
- [ ] Truncated descriptions end with "..."
|
||||
- [ ] The total length including "..." does not exceed 1024 chars
|
||||
|
||||
**Out of scope:**
|
||||
- Changing the 1024 char limit itself
|
||||
- Multi-line description support
|
||||
```
|
||||
|
||||
### Good agent brief (enhancement)
|
||||
|
||||
```markdown
|
||||
## Agent Brief
|
||||
|
||||
**Category:** enhancement
|
||||
**Summary:** Add `.out-of-scope/` directory support for tracking rejected feature requests
|
||||
|
||||
**Current behavior:**
|
||||
When a feature request is rejected, the issue is closed with a `wontfix` label
|
||||
and a comment. There is no persistent record of the decision or reasoning.
|
||||
Future similar requests require the maintainer to recall or search for the
|
||||
prior discussion.
|
||||
|
||||
**Desired behavior:**
|
||||
Rejected feature requests should be documented in `.out-of-scope/<concept>.md`
|
||||
files that capture the decision, reasoning, and links to all issues that
|
||||
requested the feature. When triaging new issues, these files should be
|
||||
checked for matches.
|
||||
|
||||
**Key interfaces:**
|
||||
- Markdown file format in `.out-of-scope/`: each file should have a
|
||||
`# Concept Name` heading, a `**Decision:**` line, a `**Reason:**` line,
|
||||
and a `**Prior requests:**` list with issue links
|
||||
- The triage workflow should read all `.out-of-scope/*.md` files early
|
||||
and match incoming issues against them by concept similarity
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] Closing a feature as wontfix creates/updates a file in `.out-of-scope/`
|
||||
- [ ] The file includes the decision, reasoning, and link to the closed issue
|
||||
- [ ] If a matching `.out-of-scope/` file already exists, the new issue is
|
||||
appended to its "Prior requests" list rather than creating a duplicate
|
||||
- [ ] During triage, existing `.out-of-scope/` files are checked and surfaced
|
||||
when a new issue matches a prior rejection
|
||||
|
||||
**Out of scope:**
|
||||
- Automated matching (human confirms the match)
|
||||
- Reopening previously rejected features
|
||||
- Bug reports (only enhancement rejections go to `.out-of-scope/`)
|
||||
```
|
||||
|
||||
### Good agent brief (PR)
|
||||
|
||||
For a PR, "Current behavior" describes the state of the diff, and the brief asks the agent to finish or fix it rather than build from scratch.
|
||||
|
||||
```markdown
|
||||
## Agent Brief
|
||||
|
||||
**Category:** enhancement
|
||||
**Summary:** Finish the contributor's `--json` output flag for `triage list`
|
||||
|
||||
**Current behavior:**
|
||||
The PR adds a `--json` flag that serializes the issue list to JSON. The happy
|
||||
path works and the diff matches the project's command structure. Two gaps
|
||||
remain: errors are still printed as human text (not JSON), and the new flag has
|
||||
no test coverage.
|
||||
|
||||
**Desired behavior:**
|
||||
With `--json`, all output (including errors) is well-formed JSON on stdout,
|
||||
and the command's exit codes are unchanged. The existing human-readable output
|
||||
is untouched when the flag is absent.
|
||||
|
||||
**Key interfaces:**
|
||||
- The command's error path should emit `{ "error": string }` under `--json`
|
||||
instead of the plain-text error
|
||||
- Reuse the existing serializer the PR already added; don't introduce a second
|
||||
|
||||
**Acceptance criteria:**
|
||||
- [ ] `triage list --json` emits valid JSON for both success and error cases
|
||||
- [ ] Exit codes match the non-JSON command
|
||||
- [ ] A test covers the `--json` success output and one error case
|
||||
- [ ] Default (non-JSON) output is byte-for-byte unchanged
|
||||
|
||||
**Out of scope:**
|
||||
- Adding `--json` to any other command
|
||||
- Changing the JSON shape of the success payload the PR already defined
|
||||
```
|
||||
|
||||

```markdown

## Agent Brief

**Summary:** Fix the triage bug

# Out-of-Scope Knowledge Base
|
||||
|
||||
The `.out-of-scope/` directory in a repo stores persistent records of rejected feature requests. It serves two purposes:
|
||||
|
||||
1. **Institutional memory**: why a feature was rejected, so the reasoning isn't lost when the issue is closed
|
||||
2. **Deduplication**: when a new issue comes in that matches a prior rejection, the skill can surface the previous decision instead of re-litigating it
|
||||
|
||||
## Directory structure
|
||||
|
||||
```
|
||||
.out-of-scope/
|
||||
├── dark-mode.md
|
||||
├── plugin-system.md
|
||||
└── graphql-api.md
|
||||
```
|
||||
|
||||
One file per **concept**, not per issue. Multiple issues requesting the same thing are grouped under one file.
|
||||
|
||||
## File format
|
||||
|
||||
The file should be written in a relaxed, readable style, more like a short design document than a database entry. Use paragraphs, code samples, and examples to make the reasoning clear and useful to someone encountering it for the first time.
|
||||
|
||||
```markdown
|
||||
# Dark Mode
|
||||
|
||||
This project does not support dark mode or user-facing theming.
|
||||
|
||||
## Why this is out of scope
|
||||
|
||||
The rendering pipeline assumes a single color palette defined in
|
||||
`ThemeConfig`. Supporting multiple themes would require:
|
||||
|
||||
- A theme context provider wrapping the entire component tree
|
||||
- Per-component theme-aware style resolution
|
||||
- A persistence layer for user theme preferences
|
||||
|
||||
This is a significant architectural change that doesn't align with the
|
||||
project's focus on content authoring. Theming is a concern for downstream
|
||||
consumers who embed or redistribute the output.
|
||||
|
||||
```ts
|
||||
// The current ThemeConfig interface is not designed for runtime switching:
|
||||
interface ThemeConfig {
|
||||
colors: ColorPalette; // single palette, resolved at build time
|
||||
fonts: FontStack;
|
||||
}
|
||||
```
|
||||
|
||||
## Prior requests
|
||||
|
||||
- #42: "Add dark mode support"
|
||||
- #87: "Night theme for accessibility"
|
||||
- #134: "Dark theme option"
|
||||
```
|
||||
|
||||
### Naming the file
|
||||
|
||||
Use a short, descriptive kebab-case name for the concept: `dark-mode.md`, `plugin-system.md`, `graphql-api.md`. The name should be recognizable enough that someone browsing the directory understands what was rejected without opening the file.
|
||||
|
||||
### Writing the reason
|
||||
|
||||
The reason should be substantive: not "we don't want this" but why. Good reasons reference:
|
||||
|
||||
- Project scope or philosophy ("This project focuses on X; theming is a downstream concern")
|
||||
- Technical constraints ("Supporting this would require Y, which conflicts with our Z architecture")
|
||||
- Strategic decisions ("We chose to use A instead of B because...")
|
||||
|
||||
The reason should be durable. Avoid referencing temporary circumstances ("we're too busy right now"); those aren't real rejections, they're deferrals.
|
||||
|
||||
## When to check `.out-of-scope/`
|
||||
|
||||
During triage (Step 1: Gather context), read all files in `.out-of-scope/`. When evaluating a new issue:
|
||||
|
||||
- Check if the request matches an existing out-of-scope concept
|
||||
- Matching is by concept similarity, not keyword: "night theme" matches `dark-mode.md`
|
||||
- If there's a match, surface it to the maintainer: "This is similar to `.out-of-scope/dark-mode.md`. We rejected this before because [reason]. Do you still feel the same way?"
|
||||
|
||||
The maintainer may:
|
||||
|
||||
- **Confirm**: the new issue gets added to the existing file's "Prior requests" list, then closed
|
||||
- **Reconsider**: the out-of-scope file gets deleted or updated, and the issue proceeds through normal triage
|
||||
- **Disagree**: the issues are related but distinct, proceed with normal triage
|
||||
|
||||
## When to write to `.out-of-scope/`
|
||||
|
||||
Only when an **enhancement** (not a bug) is *rejected* as `wontfix`. This applies to enhancement PRs exactly as it does to issues: a rejected PR is recorded here so the same request doesn't return as fresh code.
|
||||
|
||||
Do **not** write here when something is closed as `wontfix` because it's **already implemented**. That's a built feature, not a rejected one; recording it would poison the dedup checks with false rejections. Instead, the closing comment points to where the feature already lives.
|
||||
|
||||
The flow:
|
||||
|
||||
1. Maintainer decides a feature request is out of scope
|
||||
2. Check if a matching `.out-of-scope/` file already exists
|
||||
3. If yes: append the new issue to the "Prior requests" list
|
||||
4. If no: create a new file with the concept name, decision, reason, and first prior request
|
||||
5. Post a comment on the issue explaining the decision and mentioning the `.out-of-scope/` file
|
||||
6. Close the issue with the `wontfix` label
|
||||
|
||||
## Updating or removing out-of-scope files
|
||||
|
||||
If the maintainer changes their mind about a previously rejected concept:
|
||||
|
||||
- Delete the `.out-of-scope/` file
|
||||
- The skill does not need to reopen old issues; they're historical records
|
||||
- The new issue that triggered the reconsideration proceeds through normal triage

# Triage
|
||||
|
||||
Move issues on the project issue tracker through a small state machine of triage roles.
|
||||
|
||||
If this repo treats external pull requests as a request surface (see the issue-tracker config), triage covers them too: **a PR is an issue with attached code**, using the same roles, same states, and same machine, with a few deltas marked "for a PR" below. Resolve a bare `#42` to an issue or PR per the tracker config.
|
||||
|
||||
Every comment or issue posted to the issue tracker during triage **must** start with this disclaimer:
|
||||
|
||||
```
|
||||
> *This was generated by AI during triage.*
|
||||
```
|
||||
|
||||
## Reference docs
|
||||
|
||||
- [AGENT-BRIEF.md](AGENT-BRIEF.md): how to write durable agent briefs
|
||||
- [OUT-OF-SCOPE.md](OUT-OF-SCOPE.md): how the `.out-of-scope/` knowledge base works
|
||||
|
||||
## Roles
|
||||
|
||||
Two **category** roles:
|
||||
|
||||
- `bug`: something is broken
|
||||
- `enhancement`: new feature or improvement
|
||||
|
||||
Five **state** roles:
|
||||
|
||||
- `needs-triage`: maintainer needs to evaluate
|
||||
- `needs-info`: waiting on reporter for more information
|
||||
- `ready-for-agent`: fully specified, ready for an AFK agent
|
||||
- `ready-for-human`: needs human implementation
|
||||
- `wontfix`: will not be actioned
|
||||
|
||||
For a PR, the same states read against the attached code: `ready-for-agent` means a brief is attached and an agent should take the next step on the diff; `ready-for-human` means it's ready for a human to merge.
|
||||
|
||||
Every triaged issue should carry exactly one category role and one state role. If state roles conflict, flag it and ask the maintainer before doing anything else.
|
||||
|
||||
These are canonical role names. The actual label strings used in the issue tracker may differ. The mapping should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
|
||||
|
||||
State transitions: an unlabeled issue normally goes to `needs-triage` first; from there it moves to `needs-info`, `ready-for-agent`, `ready-for-human`, or `wontfix`. `needs-info` returns to `needs-triage` once the reporter replies. The maintainer can override at any time; flag transitions that look unusual and ask before proceeding.
|
||||
|
||||
## Invocation
|
||||
|
||||
The maintainer invokes `/triage` and describes what they want in natural language. Interpret the request and act. Examples:
|
||||
|
||||
- "Show me anything that needs my attention"
|
||||
- "Let's look at #42" (issue or PR)
|
||||
- "Move #42 to ready-for-agent"
|
||||
- "What's ready for agents to pick up?"
|
||||
|
||||
## Show what needs attention
|
||||
|
||||
Query the issue tracker and present three buckets, oldest first:
|
||||
|
||||
1. **Unlabeled**: never triaged.
|
||||
2. **`needs-triage`**: evaluation in progress.
|
||||
3. **`needs-info` with reporter activity since the last triage notes**: needs re-evaluation.
|
||||
|
||||
When PRs are in scope, include external PRs in these buckets and tag each line `[PR]` or `[issue]`. Discovery surfaces only *external* PRs (the tracker config defines who counts as external), so a collaborator's in-flight PR is not triage work. This filter is discovery-only; an explicitly named PR is always triaged regardless of author.
|
||||
|
||||
Show counts and a one-line summary per item. Let the maintainer pick.
|
||||
|
||||
## Triage a specific issue or PR
|
||||
|
||||
1. **Gather context.** Read the full issue or PR (body, comments, labels, author, dates; for a PR, the diff too). Parse any prior triage notes so you don't re-ask resolved questions. Explore the codebase using the project's domain glossary, respecting ADRs in the area. Run two checks against the codebase: (a) **redundancy**: search for an existing implementation of the requested behavior by domain concept (not just the request's wording), and report where you looked. If found, it's an already-implemented `wontfix` (step 5). (b) **prior rejection**: read `.out-of-scope/*.md` and surface any that resembles this request.
|
||||
|
||||
2. **Recommend.** Tell the maintainer your category and state recommendation with reasoning, plus a brief codebase summary relevant to the request (including whether it's already implemented). Wait for direction.
|
||||
|
||||
3. **Verify the claim.** Before any grilling, check that the claim holds up. For a bug, reproduce it from the reporter's steps. For a PR, confirm the diff does what it claims: check it out, run the relevant tests or commands. Report what happened: confirmed (with code path), failed, or insufficient detail (a strong `needs-info` signal). A confirmed verification makes a much stronger agent brief.
|
||||
|
||||
4. **Grill (if needed).** If the request needs fleshing out, call the Skill tool twice, for "grilling" and "domain-modeling", and grill it into shape a round of questions at a time, sharpening domain terms and updating `GLOSSARY.md`/ADRs inline as decisions land.
|
||||
|
||||
5. **Apply the outcome:**
|
||||
- `ready-for-agent`: post an agent brief comment ([AGENT-BRIEF.md](AGENT-BRIEF.md)).
|
||||
- `ready-for-human`: same structure as an agent brief, but note why it can't be delegated (judgment calls, external access, design decisions, manual testing).
|
||||
- `needs-info`: post triage notes (template below).
|
||||
- For `wontfix`, close the issue, with the comment depending on *why*:
|
||||
- **Already implemented**: the change already exists in the codebase. Point to where it lives; do **not** write to `.out-of-scope/` (that KB is for *rejected* requests, not built ones).
|
||||
- **Rejected (bug)**: give a polite explanation, then close.
|
||||
- **Rejected (enhancement)**: write to `.out-of-scope/`, link to it from a comment, then close ([OUT-OF-SCOPE.md](OUT-OF-SCOPE.md)).
|
||||
- `needs-triage`: apply the role. Optional comment if there's partial progress.
|
||||
|
||||
## Quick state override
|
||||
|
||||
If the maintainer says "move #42 to ready-for-agent", trust them and apply the role directly. Confirm what you're about to do (role changes, comment, close), then act. Skip grilling. If moving to `ready-for-agent` without a grilling session, ask whether they want to write an agent brief.
|
||||
|
||||
## Needs-info template
|
||||
|
||||
```markdown
|
||||
## Triage Notes
|
||||
|
||||
**What we've established so far:**
|
||||
|
||||
- point 1
|

- point 2

- question 1
|
||||
- question 2
|
||||
```
|
||||
|
||||
Capture everything resolved during grilling under "established so far" so the work isn't lost. Questions must be specific and actionable, not "please provide more info".
|
||||
|
||||
## Resuming a previous session
|
||||
|
||||
If prior triage notes exist on the issue or PR, read them, check whether the reporter has answered any outstanding questions, and present an updated picture before continuing. Don't re-ask resolved questions.
