Priority: P2 (MEDIUM)
1. Intent-First Comments
- Explain "Why" logic exists. Avoid "What" mechanics.
- Use triple-slash (Dart/Swift) or JSDoc (TS/JS) for public members.
- Delete commented-out code. Use Git history.
- Format:
TODO(username): description. Link tickets. - For retry backoff, explain that jitter prevents the thundering herd; document intent rather than restating the delay calculation.
2. README Structure
- Mission: Project purpose (one sentence).
- Onboarding: Prerequisites, installation, usage (exact).
- Maintenance: Document inputs/outputs, known quirks, fixes.
- Sync: Documentation ships with feature.
3. ADRs & Architecture
- ADRs: Document rationale for system changes in
docs/adr/. - Docstrings: Include Args, Returns, and Usage examples (
>>>). - Diagrams: Use Mermaid.js inside Markdown.
4. API Docs
- Use Swagger/OpenAPI for REST.
- Provide copy-pasteable examples for endpoints.
- Define contract before implementation.
Anti-Patterns
- No "what" comments: Explain intent. Refactor mechanics.
- No orphan TODOs: Require owner and ticket.
- No stale docs: Document during development.
