Which languages does the Code Cleanup skill support?

It includes specific presets for JavaScript (Knip) and Elixir (Credo), but it is designed to follow idiomatic guidelines for any language by running its specific compilation and linting tools.

Does it verify that the code still works after cleanup?

Yes, it runs your existing test suite before and after the cleanup process to assess the state of the code and ensure no regressions were introduced.

How does the skill handle large codebases?

It creates a structured plan and spawns language-specific expert agents in parallel to process multiple files or folders simultaneously, ensuring efficiency on large projects.

Will this skill automatically change my code without permission?

No, it first creates a CLEANUP.md plan and requires user approval of the proposed changes before spawning agents to execute the modifications.

Automates the identification and resolution of technical debt, linting errors, and code smells through structured planning and parallel execution.

The Code Cleanup skill streamlines the process of maintaining high-quality codebases by identifying bad patterns and fixing compiler or linter warnings automatically. It orchestrates a multi-step workflow that includes running diagnostic tools like Knip for JavaScript or Credo for Elixir, rating issue complexity, and generating a detailed CLEANUP.md plan for user approval. By leveraging parallel language-expert agents and continuous test suite validation, it ensures that even large-scale refactors are handled safely and efficiently without introducing regressions.
