# Backend Feature Implementation ## When to Use - API endpoint changes - Service or repository logic changes - Schema-sensitive backend work - Middleware or controller updates ## Procedure 1. Read `AGENTS.md`, `.github/copilot-instructions.md`, and the repository's backend instructions file (e.g., a `.instructions.md` scoped to the backend area) if present. 2. Identify the affected backend layer and contract surface. 3. **Responder** — Implement the smallest coherent backend change as a first draft. 4. **Evaluator** — Self-critique the draft before finalizing: - Does it follow conventions in `.github/instructions/conventions.instructions.md` (seeded from the project scan; fall back to `CONTRIBUTING.md` or any detected convention file if not present)? - Does it preserve all existing API contracts (no breaking changes without an explicit flag)? - Are all new service or repository functions covered by a targeted test? - Does it introduce any unsafe validation, auth, or secret handling? 5. **Revisor** — Apply corrections from the Evaluator step before writing the final code. 6. Update focused tests. 7. Record schema, contract, or rollout risks in `.github/.ai_ledger.md`. ## Output - Files changed - Contract or data impact - Tests added or updated - Open blockers
