How does this skill enforce TDD principles?

The skill mandates a strict Red-Green-Refactor cycle where Claude must write a failing test and verify its failure message before any production code can be authored.

Why is the 'Verify Red' step mandatory?

Watching a test fail confirms that the test is actually checking the intended behavior and isn't passing by accident, which is a common pitfall in tests-after development.

What is the 'Iron Law' in this TDD skill?

The Iron Law states that no production code should be written without a failing test first. If code is written prematurely, it must be deleted and restarted from the test phase.

Can this skill be used for bug fixing?

Absolutely. It requires writing a test that reproduces the bug (RED), verifying the failure, and then writing the minimal code to fix it (GREEN) before refactoring.

安全与测试

Enforces a strict Red-Green-Refactor workflow to ensure high-quality, bug-free production code through a test-first approach.

This skill implements a rigorous Test-Driven Development (TDD) methodology within Claude Code, ensuring that no production code is written without a preceding failing test. By guiding Claude through the mandatory Red-Green-Refactor cycle, it eliminates technical debt, prevents regressions, and produces cleaner, more maintainable software architecture. It is designed to foster extreme discipline, requiring developers and AI alike to verify failures before implementation and refactor only when tests are green, resulting in codebases that are robust by design.
