Default guidance

Apply the rule files in this folder as the source of truth for Bun and PostgreSQL usage.

Workflow (use this order)

  1. Clarify scope: service/API/script/task runner.
  2. Prefer Bun-native tooling (bun install, bun run, bun test, bun build).
  3. Use Bun-native APIs (Bun.serve, Bun.file, SQLite/Redis) where applicable.
  4. Design module boundaries and error handling early.
  5. Add tests with bun test and include coverage for edge cases.
  6. Validate deployment target and build output.

Review Checklist

  • Bun-native tooling used; no unnecessary Node tooling.
  • Modern JS/TS patterns (ESM, async/await, private fields) applied.
  • Error handling is centralized and user-facing errors are clear.
  • IO paths use Bun APIs for performance.
  • Tests present and runnable with bun test.
