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
