When should I use the TDD Workflow skill?

Use this skill whenever you are starting a new feature, fixing a bug, or need to refactor complex code while maintaining high test coverage.

What is the TDD Workflow skill?

It is a specialized Claude Code skill that guides developers through the Test-Driven Development cycle and Kent Beck's Tidy First principles for cleaner code.

Does this skill help with commit messages?

Yes, it encourages a discipline of small, frequent commits that clearly distinguish between structural and behavioral updates.

How does this skill handle refactoring?

It follows the 'Tidy First' approach, which requires separating structural changes from behavioral changes and ensuring structural changes happen first without altering functionality.

Can I use this for existing projects?

Absolutely. It is particularly effective for fixing bugs in existing projects by first writing a test that replicates the problem before implementing the fix.

Security & Testing

Guides development using Kent Beck’s Test-Driven Development and Tidy First principles to ensure clean, robust, and maintainable code.

This skill transforms Claude into a senior software engineer specialized in the TDD cycle (Red-Green-Refactor) and Kent Beck’s 'Tidy First' methodology. It provides a structured framework for implementing features and fixing bugs by enforcing a test-first approach and a strict separation between structural and behavioral changes. By following these principles, the skill ensures that code is minimalist, expressive, and verified by tests at every stage, making it indispensable for teams prioritizing high code quality and long-term maintainability.

Key Features
