Implements the Red-Green-Refactor cycle to ensure production-grade code reliability and architectural integrity.
This skill provides a structured framework for Test-Driven Development (TDD) within Claude Code, guiding the development process through the essential Red-Green-Refactor cycle. By enforcing the three laws of TDD and utilizing the Arrange-Act-Assert (AAA) pattern, it ensures that every line of production code is justified by a failing test. It is particularly useful for building complex logic, handling edge cases, and preventing regressions through AI-augmented patterns that can even support multi-agent collaboration for testing and implementation.
Key Features
01Behavior-focused test prioritization including happy paths and edge cases
02Strict adherence to the Red-Green-Refactor development cycle
03Standardized test organization using the Arrange-Act-Assert (AAA) pattern
04Support for AI-augmented multi-agent TDD collaboration patterns
050 GitHub stars
06Built-in prevention of common anti-patterns like skipping the RED phase
Use Cases
01Resolving complex bugs by writing failing regression tests before implementing fixes
02Refactoring legacy codebases safely by maintaining a green test state throughout changes
03Building new software features where high reliability and specification-first design are required
