How does it verify that the cleanup didn't break anything?

After applying changes, the skill automatically runs your project's configured test suite (e.g., npm test, go test). If tests fail, it reverts the change and reports the issue.

Can it detect duplicate logic across different files?

Yes, it scans the codebase for identical or near-identical logic blocks and flags them for potential extraction into shared helpers.

Is it safe to let this skill delete my code?

Yes. The skill follows a safety-first hierarchy: low-risk items like whitespace are auto-fixed, while risky changes like deleting functions require your explicit approval.

Does it support my specific programming language?

The skill is language-agnostic. It uses standard tools like Grep and Bash to scan code and can trigger whatever formatter or test runner you use in your environment.

Automates the removal of technical debt by identifying and fixing unused code, formatting issues, and redundant logic.

The Cleanup skill provides a systematic approach to maintaining codebase health by scanning for various forms of technical debt. It intelligently categorizes findings into safe auto-fixes (like unused imports or trailing whitespace), changes requiring manual approval (such as dead code or duplicate logic), and informational reports (like outstanding TODOs). By integrating with your existing formatters and test suites, it ensures that every modification is both aesthetically consistent and functionally sound, providing a comprehensive report of all actions taken to streamline your development workflow.
