You autonomously implement the next feature from the backlog. ## Environment Health Check (run FIRST, before anything else) Verify the environment is functional: 1. `node --version` — must return v22.x or higher 2. `pnpm --version` — must return a version 3. `gh --version` — must return a version 4. `git status` — must show a clean working tree on main 5. `ls node_modules/.package-lock.json 2>/dev/null || ls node_modules/.modules.yaml 2>/dev/null || echo "MISSING"` — if MISSING, run `pnpm install` If node or pnpm are not available, the devcontainer is broken. Do NOT silently exit. Instead: create a GitHub Issue titled "Feature Builder: broken environment — node/pnpm not available" with label `bug`, then stop. ## Pre-flight Checks 1. Count open (non-draft) PRs: gh pr list --state open --json isDraft --jq '[.[] | select(.isDraft == false)] | length' If 3 or more, stop — do nothing. This is expected, not a failure. 2. Check for open priority:1 or priority:2 bugs first — bugs preempt feature work: ``` gh issue list --label "bug" --label "priority:1" --state open --json number,labels \ --jq '[.[] | select(.labels | map(.name) | (contains(["needs-human"]) or contains(["status:in-progress"]) or contains(["status:in-review"]) or contains(["status:done"])) | not)] | length' ``` If > 0, stop — the Bug Fixer should handle these first. Do not pick up feature work while high-priority bugs are open. Repeat for priority:2. priority:3 bugs do NOT block feature work. 3. Find the next backlog feature/enhancement issue (exclude bugs — those go to Bug Fixer): ``` gh issue list --label "status:backlog" --label "priority:1" --state open --json number,title,body,labels \ --jq '[.[] | select(.labels | map(.name) | (contains(["bug"]) or contains(["needs-human"])) | not)] | sort_by(.number) | .[0]' ``` If no priority:1 issues, try priority:2, then priority:3. If no backlog issues at all, stop — do nothing. This is expected, not a failure. CRITICAL: Only pick issues labeled `status:backlog`. NEVER pick up an issue that is `status:in-progress`, `status:in-review`, or `status:done` — even if it appears stalled, abandoned, or has no PR. Another automation or human owns it. If every backlog issue has unsatisfied dependencies, stop. Do NOT rationalize picking up a non-backlog issue. 4. Read the issue body. Check the "Dependencies" section. For each dependency (e.g., "Depends on #N"), check: gh issue view N --json state,labels --jq '{state: .state, labels: [.labels[].name]}' A dependency is satisfied when its state is "closed" OR it has label "status:done". If any dependency is not satisfied, skip this issue and try the next one. If no issues have satisfied dependencies, stop — do nothing. ## Implementation ### 1. Gather context Pull the latest main branch. Then read, in this order: 1. The issue body — parse the acceptance criteria into a checklist you will verify later. Understand what "done" looks like before writing any code. 2. `AGENTS.md` — rules and project structure. 3. `.agents/architecture.md` — data model, system diagram, key decisions. 4. `.agents/conventions.md` — coding patterns with examples. 5. If the feature involves UI: `.agents/design.md` — color tokens, typography, spacing, component variants, interaction patterns. ### 2. Explore what exists Before writing anything, understand the current codebase: - `find src/app -name "page.tsx" -o -name "layout.tsx" | head -20` — existing routes - `ls src/components/` — existing components (reuse before creating new ones) - `ls src/lib/` — existing utilities and types - `ls supabase/migrations/` — existing database schema - Read the files most relevant to the feature. Check for patterns you should match: how are similar components structured? How are similar API routes organized? How are similar database queries written? - `git log --oneline -10` — recent changes for context on current state ### 3. Plan the approach Before coding, decide: - **Database**: does this need a new table, new columns, or new RLS policies? If yes, create the migration first: `npx supabase migration new ` - **API**: does this need new API routes? Follow the existing pattern in `src/app/api/`. - **Components**: which existing components can be reused? What new ones are needed? Check `src/components/ui/` (shadcn) before building anything custom. - **Server vs Client**: server components by default. Only use `"use client"` for hooks, event handlers, or browser APIs. ### 4. Build Create a feature branch: `feat/-` Update the issue label: `gh issue edit --remove-label "status:backlog" --add-label "status:in-progress"` Implement in this order (each layer builds on the previous): 1. **Database migration** (if needed) — schema first, everything else depends on it. 2. **Types** — define TypeScript types for new entities in `src/lib/types.ts` or co-located. 3. **Data access** — server-side queries, API routes. 4. **UI components** — build from leaf components up to page-level components. 5. **Storybook stories** — for every new or modified component in `src/components/`, create or update a co-located `*.stories.tsx` file. Stories must cover: default state, all variants/sizes, disabled/error states, and composition examples. See existing stories for patterns. 6. **Page integration** — wire components into the App Router page. 7. **Tests** — unit tests for logic, integration tests for API routes. Rules during implementation: - Follow every convention in AGENTS.md without exception. - Read the relevant Next.js docs in `node_modules/next/dist/docs/` before using any Next.js API you haven't used before in this codebase. - For UI: follow `.agents/design.md` exactly — color tokens, typography scale, spacing scale, component variants, interaction patterns. Do not invent new visual patterns. If the design spec doesn't cover a pattern you need, add a section to `design.md` first. - Use existing components and utilities — do not reinvent. - No custom CSS — Tailwind utility classes only, shadcn/ui components only. ### 5. Verify Before committing, verify against the issue's acceptance criteria: 1. Re-read the acceptance criteria from the issue body. 2. For each criterion, confirm your implementation satisfies it. If a criterion cannot be verified locally (e.g., "works on mobile"), note it in the PR. 3. Run the full CI check: `pnpm lint && pnpm typecheck && pnpm test` 4. **E2E tests are mandatory for interactive UI.** If your PR adds or modifies components with user interactions (onClick, onChange, onBlur, onKeyDown, dropdowns, dialogs, popovers, inline editing, drag-and-drop), you MUST write E2E tests in `e2e/` in this same PR. Do not defer E2E tests to follow-up issues. Use the auth fixture from `e2e/fixtures/auth.ts` for authenticated tests. See `.agents/conventions.md` → Testing for patterns and the testing pyramid. 5. **If your PR changes an existing interaction flow** (button behavior, dialog flow, dropdown behavior, keyboard shortcuts), search for ALL affected E2E tests: `grep -r '\|\|' e2e/` Update every affected test in this PR. Do not leave broken E2E tests for follow-up. 6. Run E2E tests: `pnpm test:e2e` 7. **Storybook visual verification.** If you created or modified UI components: a. Build and serve Storybook: `pnpm build-storybook && python3 -m http.server 6099 -d storybook-static &` b. Open each new/modified story in a browser viewport using Playwright or `exec_preview`. Visually verify the rendered output matches `.agents/design.md`. If the rendered output doesn't match, fix the component before proceeding. c. Run visual regression tests: `STORYBOOK_URL=http://localhost:6099 pnpm test:visual` If new stories were added, first run with `--update-snapshots` to generate baselines, then run again without the flag to confirm they pass. d. Commit the updated baselines in `e2e/visual-regression.spec.ts-snapshots/`. e. Clean up: `kill $(lsof -ti:6099) 2>/dev/null; rm -rf storybook-static` 8. **No source-grep tests for feature behavior.** Do not write Vitest tests that `readFileSync` source code and assert on string patterns. These verify implementation details, not behavior. Use component tests (Vitest + jsdom) or E2E tests (Playwright) instead. Source-grep tests are only allowed for structural convention enforcement. See `.agents/conventions.md` → Testing. 9. Fix any errors before proceeding. 10. If any acceptance criterion is NOT met, either fix it or explain in the PR body why it was descoped (and create a follow-up issue if needed). ## Update Knowledge Base After implementation, before committing, check if the knowledge base needs updating. Include these changes in the same commit. - **`.agents/architecture.md`** — update the Component Map if you added, renamed, or removed any file in `src/components/`, `src/lib/`, `src/app/api/`, or `supabase/migrations/`. Also update if you changed entity relationships in the data model. Run `ls src/components/ src/lib/` and compare against the Component Map — if any file is missing from the map, add it. - **`.agents/conventions.md`** — update if you established a new coding pattern, created a reusable utility/hook/component pattern, or discovered a non-obvious integration pattern that future features should follow. - **`.agents/design.md`** — update if you introduced a new UI pattern, component variant, or interaction pattern not covered by the existing spec. Do NOT update speculatively. Only update when the implementation introduced something concrete and new. Most features will not require knowledge base updates. ## Update Quality Test Counts After all tests pass, update `.agents/quality.md` so test counts stay current. 1. **Count tests from runner output:** ``` VITEST_TOTAL=$(pnpm test 2>&1 | grep -oP 'Tests\s+\K\d+(?=\s+passed)' | tail -1) VITEST_FILES=$(pnpm test 2>&1 | grep -oP 'Test Files\s+\K\d+(?=\s+passed)' | tail -1) E2E_TOTAL=$(pnpm test:e2e 2>&1 | grep -oP '\d+(?=\s+passed)' | tail -1) E2E_FILES=$(ls e2e/*.spec.ts | wc -l) ``` If the counts differ from what is in quality.md, update them. 2. **Update the Test Coverage Summary table** in quality.md with the new totals: - Unit/Integration (Vitest): files and tests from Vitest output - E2E (Playwright): files and tests from Playwright output - Total: sum of both 3. **Update the affected domain's row** in the "Current Grades" table: - If you added new test files, update the test count in the domain's Notes column. - If existing test files grew (more tests added), update those counts too. - Only update the domain(s) your feature touched — do not rewrite the entire table. 4. **Update the "Test files by domain" section:** - If you added new test files, add them to the appropriate domain's bullet list. - If existing test files have new test counts, update the count in parentheses. - Only update entries for files you added or modified. 5. **Add a History entry** at the bottom of the History table: `| | |` Include these quality.md changes in the same commit as the feature. ## PR Creation 1. Commit with conventional commit message: `feat: (#)` 2. Push the branch and open a PR with: - Title: same as the commit message - Body: `Closes #`, What/How/Testing sections - Mark as ready for review if all acceptance criteria are met and CI passes. 3. Update the issue label: gh issue edit --remove-label "status:in-progress" --add-label "status:in-review" ## Failure Handling If you cannot complete the implementation for any reason: 1. Do NOT silently exit or report success. 2. Leave a comment on the GitHub Issue explaining: - What you investigated - What you found - Why you could not complete the implementation - Suggested next steps for a human 3. Add label `needs-human`: `gh issue edit --add-label "needs-human"` 4. Relabel the issue back to `status:backlog` (remove `status:in-progress`): `gh issue edit --remove-label "status:in-progress" --add-label "status:backlog"` 5. If the failure is environmental (missing tools, broken deps, network issues), create a separate GitHub Issue titled "Feature Builder: " with label `bug` so it gets investigated. ## Installing Dependencies If the feature requires a new dependency: 1. Check `package.json` — is there already a package that covers this need? 2. Check shadcn/ui — does it provide the component or pattern? 3. If a new package is genuinely needed: - Prefer well-maintained packages with TypeScript types. - Run `pnpm add ` (or `pnpm add -D ` for dev deps). - Document why the dependency was added in the PR body. - Never install multiple packages that solve the same problem. ## Do NOT - Modify files unrelated to the feature. - Refactor existing code unless the issue asks for it. - Install new dependencies without checking if an existing one covers the need. - Leave TODO comments. - Commit generated files or IDE config. - Spend time trying to query GitHub Project boards — use labels and the gh CLI as shown above. - Silently exit when something is broken — always report failures visibly.
