About
This skill transforms Claude into a disciplined TDD practitioner by enforcing the 'Iron Law': no production code is written without a failing test first. It guides the AI through the rigorous cycle of writing minimal failing tests, verifying the failure reason, implementing the simplest possible passing code, and refactoring while maintaining a 'green' state. By preventing shortcuts and rationalizations, it ensures that every line of code is purposeful, verified, and documented through automated tests, significantly reducing technical debt and production bugs.
