macOS Disk Cleanup Advisor

Safely analyzes macOS disk usage and produces a cleanup report that explains the real cost of deleting each item.

UtilitiesIntermediate★ 1,323⑂ 212AI score 9/10Last updated: Aug 8, 2026

What it does

  • Runs Mole (mo analyze) inside tmux plus bundled Python scripts to scan caches, logs, app remnants, large files, and dev tooling (Docker, npm, Homebrew, pip).
  • Classifies every finding as 🟢 safe / 🟡 trade-off / 🔴 do not delete, always with an "impact if deleted" column.
  • Bans all docker ... prune commands; requires per-object inspection and deletion by explicit image/volume name.
  • Never auto-deletes: Claude hands you the commands, then verifies with df -h before/after.

Who it's for

  • Mac users out of disk space with no idea what's eating it.
  • Developers sitting on tens of GB of Docker images and volumes.
  • Anyone burned by wiping useful caches (the skill factors in slow networks and redownload cost).

Examples

  1. "My Mac is out of space" → quick diagnosis and a report like "45 GB in ~/Library/Caches, but keep the npm cache — 2 hr redownload".
  2. "Clean up my dev environment" → scripts/analyze_dev_env.py lists Docker volumes per project before proposing precise docker volume rm commands.
  3. "What's using all my space?" → top 20 files over 100 MB grouped into videos, datasets, archives, and disk images.
