How do I trigger the TDD workflow?

You can initiate the workflow by using the command /cast:tdd followed by the name of the feature or function you want to develop.

What is the TDD skill for Claude Code?

The TDD skill is a specialized capability that guides Claude through the Red-Green-Refactor cycle, ensuring all new code is validated by tests before implementation.

What are the benefits of using TDD with AI?

Using TDD with Claude prevents the AI from generating 'hallucinated' or incorrect logic by forcing it to prove its code works against a concrete test suite.

Does this skill work with any programming language?

Yes, as long as your environment has a testing framework configured, the TDD skill can adapt to the language and testing tools used in your project.

Can I use this for refactoring existing code?

Absolutely. The 'Refactor' step of the cycle is specifically designed to improve code structure and readability while ensuring the existing tests remain green.

Security & Testing

Automates the Test-Driven Development lifecycle using a disciplined Red-Green-Refactor cycle to ensure high-quality, bug-free code.

This skill implements a professional TDD workflow within Claude Code, guiding the AI through the essential steps of modern software craftsmanship. By enforcing the Red-Green-Refactor cycle, it ensures that every feature is backed by a failing test before implementation begins, followed by the minimal code necessary to pass, and finally a dedicated refactoring phase. This approach is ideal for developers who want to reduce technical debt, improve code reliability, and maintain high test coverage while leveraging AI for rapid feature development.
