Can I choose which types of refactoring are applied?

Yes, you can set an aggressiveness level (Conservative, Moderate, or Aggressive) to control the priority and risk level of the refactorings the skill attempts.

Does this skill work without an existing test suite?

No, this skill requires a passing test suite to validate that refactoring does not change the code's behavior. If no tests exist, the process will halt for safety.

How does the automatic rollback feature work?

If a refactoring change causes a test to fail, the skill automatically uses git to revert the changes and logs the failure before moving to the next opportunity.

Does this skill modify my tests?

No, a core safety rule of this skill is that it will never modify your tests to make them pass; it only modifies implementation code to improve quality while keeping tests green.

Safely improves code quality through automated, test-driven refactoring with built-in validation and rollback safety.

This skill provides a systematic approach to reducing technical debt by identifying and applying code improvements such as method extraction, duplication removal, and conditional simplification. It operates with a safety-first mindset, requiring existing tests to pass before and after each incremental change and automatically rolling back any modification that causes a regression. Whether you are cleaning up a large function or renaming variables for clarity, this skill ensures your codebase remains functional and maintainable through risk-based prioritization and continuous validation.
