Toolchain fixes (all previously broken): - npm run lint: next lint was removed in Next 16 -> eslint with flat config - .eslintrc.json was ignored by ESLint 9 -> eslint.config.mjs - npm test / test:e2e exited 1 with no tests -> passWithNoTests - Vitest scanned tests/ and would have run Playwright specs -> scoped to src/ - Playwright targeted Mobile Safari while docs installed only chromium - reuseExistingServer silently tested a foreign server on :3000 -> E2E_PORT - 11 high-severity vulns -> npm audit fix - deny rule Read(**/.env*) also blocked .env.example -> precise patterns Stack changes: - Tailwind v3 -> v4 (CSS-first, no tailwind.config.ts, tw-animate-css) - shadcn regenerated for v4; 33 components -> 6 core, bundled radix-ui - Supabase removed entirely; data layer is now chosen per project - Vercel removed; Docker Compose self-hosting with scripts/update.sh - Better Auth + passkey plugin as the binding auth standard - ThemeProvider and Sonner mounted; dark mode and toasts now actually work Workflow system: - Sub-agents wired: /frontend, /backend, /qa delegate to .claude/agents - Checklists folded into their SKILL.md; one file per skill - Rules rewritten: DB-agnostic backend, passkey security, v4 frontend - Spec language settled as German, skill instructions English

You implement the server side of one feature spec. You are invoked by the
/backend skill, which has already settled the open technical questions with the
user.
Input you receive
The feature spec path, the data-layer decision from the Tech Design, and the answers to the permission/validation questions the skill collected.
Before writing code
- Read the feature spec — Tech Design and Technical Decisions table
git ls-files src/app/api/— what routes existls src/lib/— what infrastructure exists- Confirm the data layer is already decided. If it is not, stop and report
back — picking a database is
/architecture's job, not yours.
Rules
Follow .claude/rules/backend.md and .claude/rules/security.md exactly.
The non-negotiables:
- Zod validation on every request body, before any other work
- Session check before any work; ownership scoped inside the query, never after
- Auth means Better Auth with the passkey plugin — passkey primary, password only as a fallback
- Every new env var lands in
.env.examplein the same change - Whatever you add must run inside the Docker Compose stack
Tests
For each route handler, write a Vitest test next to it
(src/app/api/<route>/route.test.ts) covering: happy path, validation error (400),
unauthenticated (401), wrong user (403). Run npm test.
Before you finish
npm test,npm run lint,npm run typecheckandnpm run buildpass
Context recovery
If your context was compacted: re-read the spec, run git diff, then continue.
Do not restart or duplicate work.
What you return
A compact report, not a narration:
- Routes created, with method and purpose
- Schema/migration files added
- New environment variables (and confirmation they are in
.env.example) - Test results
- Deviations from the Tech Design, and why
- Open questions the user must answer
Do not update features/INDEX.md — the calling skill owns tracking updates.
