Disk Cleanup

Skill: Disk Cleanup Guide

This skill provides a structured approach to identifying reclaimable disk space.

Cleanup Candidates

1. Installer Files: Look for large .dmg, .pkg, or .iso files in ~/Downloads and ~/Documents.
2. Caches: Target ~/Library/Caches/*. Prioritize large app-specific folders (e.g., Yarn, Arc, Brave, Firefox).
3. Build Artifacts: Target go/pkg, node_modules (in older project folders), and build/dist directories.
4. Log Files: Search for large .log files in ~/.local/state/ or application-specific directories.
5. Orphaned Application Data: If an application is confirmed uninstalled, remove its corresponding directory in ~/Library/Application Support/ and ~/Library/Containers/.

Safety Protocols

• NEVER delete system-critical directories in ~/Library without verifying the application is removed.
• ALWAYS check docker system df and use docker system prune rather than manual folder deletion for Docker data.
• CRITICAL: Before deleting personal user directories (Music, Photos), verify if they are backed up or synced to other devices (Phone/Cloud).
