Does this skill work with languages other than PHP?

While the conceptual workflow is universal, this specific implementation is pre-configured for PHP environments utilizing tools like PHPUnit, PHPStan, and PHP-CS-Fixer.

Can I target specific files for refactoring?

Yes, the skill accepts file or folder arguments, allowing you to precisely control which parts of your application are being refactored.

What happens if a refactor breaks my tests?

The skill is designed with a safety-first approach; if a transformation causes a test failure that isn't immediately fixable, it automatically reverts the changes to ensure the codebase remains stable.

Does the skill automatically commit changes to my repository?

No, the skill has an explicit restriction against creating Git commits, ensuring that you have the final say and can review all changes before they are finalized.

How many iterations does the skill perform?

To prevent infinite loops or excessive changes, the skill is limited to a maximum of 5 refactoring iterations per file.

Developer Tools

Automates complex code refactoring through a rigorous, test-driven iterative loop to ensure code quality and stability.

The implementer:refactor skill is designed to handle the heavy lifting of code maintenance by following a strict 'Refactor/Test/Adjust' cycle. It begins by establishing a performance baseline using PHPUnit and static analysis, then identifies and executes specific architectural improvements such as method extractions, type-hinting updates, and condition simplifications. By enforcing a rule that tests must remain green at every iteration, it allows developers to safely pay down technical debt and improve maintainability without the risk of introducing regressions.
