Refactors source code to improve maintainability and clarity without altering functional behavior.
The File Cleaner skill is a specialized utility for Claude Code designed to transform messy or legacy source files into clean, readable, and professional code. It focuses on non-semantic improvements such as renaming ambiguous variables to intent-revealing names, pruning redundant comments, and ensuring strict adherence to style guides and linting rules. By prioritizing documentation that explains 'why' logic exists rather than just 'what' it does, this skill helps developers reduce technical debt and prepare codebases for easier long-term maintenance while providing a clear diff for manual verification.
