What is the Red-Green-Refactor cycle?

It is the core TDD process: write a failing test (Red), write minimal code to pass the test (Green), and then clean up the code while keeping tests passing (Refactor).

Can this skill detect if I am not following TDD?

Yes, it includes a compliance script that detects code smells like deep nesting or long methods which often indicate 'test-after' development rather than TDD.

When should I avoid using this skill?

Avoid using it for pure design discussions, documentation-only tasks, or research exploration where implementation isn't the immediate goal.

Does it work with specific programming languages?

The methodology and patterns provided are language-agnostic, though the included validation scripts are designed to support common development environments.

セキュリティとテスト

Enforces strict Test-Driven Development cycles to ensure high code quality and comprehensive test coverage.

概要

The TDD Methodology Expert skill transforms Claude Code into a disciplined development partner that prioritizes testing before implementation. It guides developers through the Red-Green-Refactor cycle, providing automated validation scripts to detect code smells and ensure adherence to TDD principles. By breaking down complex requirements into testable increments, this skill helps maintain a clean codebase, reduces regressions, and ensures that every line of production code is backed by a verified requirement.
