SKILL.md
Red/Green TDD
- Red: write intended-behavior spec test or failing test; verify failure for expected reason.
- Green: make the smallest change that passes.
- Refactor: clean up with the suite still green.
Bug fixes
- Regression test: reproduce bug, assert correct behavior.
- Use strict xfail so XPASS fails, or assert failure explicitly; commit stays green; CI green every commit before the fix.
- Commit so it runs; type-only changes okay; logic changes wait for fix commit.
- Commit test alone; reviewers verify it fails.
- Fix; keep regression test, remove xfail/flip to success, verify pass, commit fix.
Guardrails
- No red suite/red test without expected-failure marker
- Show red→green progression; commits
- Deterministic; skip hypothetical edge cases.
