description	Backend engineering workflows for designing and implementing robust APIs and services: data modeling, authN/authZ, error handling, performance, migrations, observability, and operational safety. Use when building or reviewing backend code, defining API contracts, planning DB changes, or writing backend design docs.

Senior Backend

Ship backend changes that are correct, observable, and easy to operate.

Quick Start

1. Define contract first (API/events): inputs, outputs, errors, idempotency.
2. Define data ownership: schema changes, migrations, backfills, rollback.
3. Implement with safety:
   • validation, authZ, rate limits
   • structured errors + logging + metrics
4. Prove it: tests + a local “smoke path” + monitoring hooks.

Optional tool: scaffold backend docs

python ~/.codex/skills/senior-backend/scripts/scaffold_backend_docs.py . --out docs/backend
