Tdd Workflow

sickn33/antigravity-awesome-skills
913 installs43.1k stars
Summary

This is a structured reference for Claude to follow test-driven development's RED-GREEN-REFACTOR cycle. It walks through the three phases with concrete rules: write a failing test, implement just enough code to pass it, then refactor while keeping tests green. The AAA pattern (Arrange-Act-Assert) and three laws of TDD are laid out clearly, which is helpful if you want Claude to write tests before code or help enforce discipline around minimal implementations. The anti-patterns section is a nice touch. It's basically a cheat sheet to keep TDD workflows consistent, though you'll still need to guide Claude on what specific behavior to test first.
