How does this skill handle bug fixes?

It follows a specific bug-fix checklist: first, write a test that reproduces the bug (RED), confirm it fails, implement the minimal fix (GREEN), and then verify all tests pass.

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 before a test, it must be deleted to ensure the TDD process is followed correctly.

Why does this skill have a 'LOW FREEDOM' rigidity level?

TDD relies on a specific sequence to be effective. The low freedom level ensures the AI doesn't take shortcuts that would compromise the reliability of the tests or the resulting code.

Can I skip the 'Verify RED' phase?

No. Verifying the failure is mandatory because it proves the test is actually testing the missing feature and isn't passing by accident or due to a configuration error.

Which programming languages are supported?

This skill includes native support and command examples for Go, TypeScript (Vitest), Rust (Cargo), and Python (Pytest).

セキュリティとテスト

Enforces a strict Red-Green-Refactor workflow to ensure all production code is verified by failing tests first.

The Test-Driven Development (TDD) skill for Claude Code provides a rigorous framework for implementing features and fixing bugs through the Red-Green-Refactor cycle. By mandating that a failing test must exist before any production code is written, it eliminates the risks associated with writing tests after the fact, such as false positives or untested edge cases. This skill is built for developers who prioritize software reliability, providing specific commands for Go, TypeScript, Rust, and Python, while enforcing the 'Iron Law' of TDD: if you didn't watch it fail, you don't know if it works.
