Codebase Cleanup Refactor Clean

This is a structured refactoring assistant that helps you clean up technical debt without going overboard. It breaks down cleanup work into small, testable steps and focuses on high-impact changes like removing duplication and improving readability. The skill explicitly pushes back on large rewrites, keeping changes reviewable and reversible. It's built for the common scenario where you need to tidy up a codebase before adding features, not for quick fixes or documentation tasks. The output gives you a prioritized plan with risk notes rather than just dumping refactored code at you. Good fit if you want guardrails around refactoring scope instead of an enthusiastic rewrite-everything approach.
