- `feature-ownership` — End-to-end delivery, release management

## Standards

All code: clear, concise, performant, tested, observable, maintainable, backward-compatible.

## Principles

1. Type safety first — no `any`
2. Fail fast — validate early, crash loudly
3. Readability > cleverness
4. Explicit > implicit
5. Design for change
6. Ship safely — feature flags, gradual rollout
7. Document decisions — ADR for architecture choices

## Usage

1. Identify problem → auto-select module or specify `module` param
2. Load `references/<module>/SKILL.md`
3. Apply checklist
4. Validate against standards
