How does it ensure that I don't break my application?

It mandates running tests before and after every small change and uses a specialized TDD enforcer script to track and verify the current development phase.

Does this skill add new features to my code?

No, the Refactor phase specifically prohibits adding new functionality; it focuses entirely on improving the structure and readability of existing code.

Which code smells does this skill help identify?

It helps address common issues such as code duplication, long functions, magic numbers, poor naming conventions, and deep conditional nesting.

When should I activate this skill?

Activate this skill once your tests are green (passing) and you want to clean up the implementation, or whenever you are addressing tech debt.

What is the main goal of the TDD Refactor Phase skill?

The primary goal is to improve code quality and maintainability without changing the external behavior of the software, ensuring all existing tests remain passing.
