Individual skill

tdd

Test-first cycle and red-step evidence rule for skills that implement behavior a test can assert. Binds when the verification skill resolves a test command; defines what the red run must quote and when the cycle is skipped with a reason.

# TDD

Reference skill read by `/plan` Step 5, `/work` Phase 3 and `skills/work/orchestrator.md`, and `/hypothesis-debugging` Step 7; `/ship` names it where it hands the build to `/work`. It is never invoked and runs nothing itself: the consumer resolves the test command per `skills/verification/SKILL.md`, follows the cycle here, and quotes the evidence.

## Applicability

The cycle binds to a change when both hold:

- The consumer resolved the test command per `skills/verification/SKILL.md` and the value is not `none`.
- The change produces behavior a test can assert. Documentation, a config value, a rename with no behavior change, and a migration with no code path do not.

When either fails, the outcome is `skipped: <reason>`, and the reason names which one: `test command none (<verification's reason>)` or `no testable behavior (<what the change is>)`. A skipped cycle is a recorded fact, not an error, and it never blocks the consumer.

The user's own project instructions win. A project whose `CLAUDE.md` says not to use TDD settles it.
