Test-Driven Development skill
Enforces a red-green-refactor workflow before any implementation code is written. The agent writes failing tests first, implements the minimum code to make them pass, then refactors. Includes patterns for unit tests, integration tests, and edge case generation.
Why it matters
TDD with AI agents produces dramatically fewer regressions. The agent treats tests as the specification, not an afterthought. Part of Jesse Vincent's battle-tested "Superpowers" skill library (20+ skills).
