Superpowers: Test-Driven Development (Crush Adaptation)
Based on obra/superpowers test-driven-development skill. (MIT)
Upstream reference: skills/test-driven-development/SKILL.md
The iron law
NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
If you wrote code before seeing the test fail:
- Delete that code.
- Re-implement from the tests.
Cycle: RED → GREEN → REFACTOR
- RED: write one minimal behavior test, run it, confirm it fails for the right reason (not syntax).
- GREEN: write the smallest implementation to pass.
- REFACTOR: clean up while staying green.
Exceptions
Only with explicit user approval (throwaway prototypes, config-only changes, etc.).
Stop conditions
If you cannot get a clean RED (fails correctly), stop and fix the test until it fails correctly.
