Test-Driven Generation

概要

Test-Driven Generation (TDG) brings the discipline of Test-Driven Development (TDD) to Claude Code, guiding the development process through structured cycles of testing and implementation. The skill manages the entire lifecycle of a feature—from identifying issue numbers and establishing test coverage baselines to writing failing tests, implementing functional code, and refactoring for optimization. By enforcing specific commit message patterns and verifying development phases with helper scripts, TDG ensures that every line of code is verified, traceable to an issue tracker, and adheres to professional software engineering standards.
