Implementing Issues

Work through an issue with TDD, proper branch management, and PR creation.

Workflow

1. Auto-detect VCS -- jj root succeeds -> jj, otherwise git
2. Auto-detect issue tracking -- numeric/#number -> GitHub (gh), TEAM-ID format -> Linear (linear-cli)
3. Check working copy status -- ensure not on main/master/dev
4. Create feature branch with proper naming
5. Read and understand issue requirements
6. Review project context -- spec.md, requirements.md, CLAUDE.md
7. Follow TDD -- write tests first
8. Implement minimal code to pass tests
9. Refactor incrementally while maintaining coverage
10. Clean up history -- squash/curate commits
11. Push with upstream tracking and create PR
12. Write complete PR description with test plan
