What is the 'iron rule' of this TDD skill?

The iron rule states that no implementation code should be written without a test first. If implementation code is written prematurely, it must be deleted and restarted with a test.

When should I not use the TDD skill?

TDD is typically waived for exploratory prototyping, configuration changes, documentation updates, or trivial one-line fixes with existing coverage.

Does this skill help with code coverage?

Yes, it targets 100% behavior coverage, ensuring that every intended functionality is verified by a test, rather than just focusing on arbitrary line coverage.

Can I use this with other teampowers plugins?

Yes, it is designed to integrate seamlessly with the team-driven-development and verification-before-completion skills for a holistic development workflow.

How does it handle refactoring?

Once a test passes (Green), the skill guides the refactoring phase to clean up the code while continuously running tests to ensure functionality remains intact.

Seguridad y Pruebas

Enforces a strict Red-Green-Refactor workflow by requiring failing tests before any implementation code is written.

The Test-Driven Development skill implements the 'iron rule' of the teampowers methodology within Claude Code, ensuring that no implementation logic is created without a preceding test. By guiding Claude through the Red-Green-Refactor cycle, this skill shifts the development focus from implementation details to verifiable behavior. It is designed for developers who prioritize high-quality, maintainable codebases and want to eliminate technical debt by ensuring 100% behavior coverage across their applications.
