Audit and reclaim disk space on macOS. Discovers cache hogs, dev caches, dead app data, old Downloads, dup installers, obsolete container images and volumes, merged worktrees, and stale node_modules/.venv dirs. Use when user says 'clean disk', 'free up space', 'computer-clean', 'cleanup mac', 'disk full', or shows ≥85% disk usage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Computer Clean - macOS Disk Cleanup
Goal: surface the largest reclaimable space on the user's Mac, classify by risk, **always confirm before destructive ops**, then execute.
## Operating principle
**Audit → Classify → Confirm → Execute → Verify.** Never skip the confirm step for 🟡/🔴 buckets. The 🟢 cache bucket can run after a single user "go".
The skill **discovers** what's actually on the user's machine - don't assume specific apps/caches exist. Run audit commands first, then classify what was found.
---
## Phase 1 - Audit (read-only)
Run these in parallel. Report top consumers per bucket.
Never run `du -sh ~/*` in the foreground: a large project tree (`~/git`, `~/projects`) can take over 10 minutes and stall the audit. Size dotdirs one by one with a timeout, and size project roots per child in the background.
Stock macOS has no `timeout`. It comes from Homebrew coreutils, as `timeout` or `gtimeout`. The `tmo` helper defined in each block uses whichever one exists, and without either it runs the command with no time limit. A `${T:+$T 60}` prefix would break under zsh, which does not word-split.

How to install
mdr add vanducng/skills/computer-clean@sha256:fc51b254a4ec07b2The line at the top of this page pins the label v1.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
