Mac Disk Cleanup

Purpose

Systematically find and reclaim disk space on macOS without losing important data. Covers the full spectrum — from obvious caches to deep audio plugin libraries and orphaned dev dependencies that silently eat storage.

When to Use

• User says "clean up space", "disk full", "free up storage", "what's using space"
• Disk free drops below 15% of total
• Before large installs or project work that needs headroom
• Periodic maintenance (monthly recommended)

What This Skill Produces

1. Disk audit report — ranked table of all major consumers
2. Actionable cleanup plan — categorized by risk (safe cache / recoverable deps / permanent removal)
3. Executed removals — with before/after space comparison
4. Sudo command block — for system-level removals that need Terminal
