Enforces a strict Red-Green-Refactor cycle to ensure all production code is verified by failing tests first.
This skill implements a rigorous Test-Driven Development (TDD) workflow for Claude, mandating that every feature or bug fix begins with a failing test. By following a strict 'Low Freedom' rigidity level, it prevents the common pitfall of writing tests after implementation, ensuring that tests actually verify intended behavior and edge cases. It guides the AI through writing minimal code to pass tests and performing safe refactoring, ultimately leading to higher code quality, better design, and reduced technical debt through systematic verification.
