Can I use this for fixing bugs?

Yes, the skill provides a specific workflow for reproducing bugs with a failing test before implementing a fix to ensure the bug is truly understood and resolved.

How does this skill handle refactoring?

It guides you through the Refactor phase only after a 'Green' state is achieved, ensuring that code cleanup happens while tests remain passing and behavior is preserved.

Does it allow for 'tests-after' implementation?

No, the skill strictly discourages writing tests after implementation because 'tests-after' often only verify what was built rather than what was required.

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

The Iron Law dictates that no production code can be written until a test has been written and verified to fail first. If code is written before a test, it should be deleted and rewritten.

安全与测试

Enforces the disciplined Red-Green-Refactor cycle by ensuring no production code is written without a preceding failing test.

The Test-Driven Development (TDD) skill transforms Claude into a rigorous engineering partner that adheres to the 'Iron Law': no production code exists without a failing test first. It guides developers through the complete Red-Green-Refactor lifecycle, providing specific validation steps, preventing common rationalizations for skipping tests, and ensuring that every feature or bug fix is backed by a verifiable, minimal test suite. By mandating that tests fail for the right reasons before implementation begins, this skill helps teams eliminate technical debt, document behavior through code, and maintain a high-confidence codebase.
