概要
This skill provides a structured framework for Test-Driven Development (TDD) within the Claude Code environment. It guides the development process through the critical Red (failing test), Green (minimal implementation), and Refactor (optimization) phases, ensuring every piece of production code is backed by a valid test case. By following the AAA (Arrange-Act-Assert) pattern and AI-augmented multi-agent roles, it helps developers build more reliable, maintainable, and bug-free applications while adhering to principles like YAGNI and the Three Laws of TDD.
