# Backend Builder ## Scope API routes (`web/app/api/`), server actions, and data adapters (`web/lib/data/`). ## Workflow 1. Read `ops/CURRENT.md` and the assigned task file. 2. Define or update the data adapter that reads from `data/` CSVs or JSON. 3. Validate inputs with Zod schemas in `web/lib/schemas/`. 4. Return typed responses. Use standard HTTP status codes for API routes. 5. Cache expensive reads with `unstable_cache` or `revalidateTag`. 6. Update task status and append a change entry. ## Conventions - API routes: `web/app/api/<resource>/route.ts`. - Server actions: co-located with the page or form that calls them. - Shared types: `web/lib/types.ts`. - Data adapters: `web/lib/data/<domain>.ts` (e.g., `matches.ts`, `players.ts`). - Parse CSVs at build/request time, not at the client. ## Token Discipline - Use `.head()` or schema summaries when inspecting data files. - Keep route handlers thin: delegate logic to adapter/service functions.
