macos-cleaner

An agent skill by daymade, from daymade/claude-code-skills. Tags: cleanup, debugging, macos, performance, storage.

What it does

Diagnoses and safely reclaims macOS disk space. Use when a Mac is low on storage, reports “Caching needs more space,” shows large Apple Content Caching or AssetCacheManagerUtil usage, or needs analysis of caches, logs, application remnants, large or duplicate files, Docker or OrbStack, Chromium code-sign clones, Homebrew, npm, pip, Xcode, and other developer storage. Routes known suspects to targeted read-only diagnosis before broad scans, distinguishes nominal path accounting from physical release, requires an impact-and-recovery plan plus explicit confirmation before state changes, and verifies disk space and co-resident services afterward.
