macOS disk cleanup, cache pruning, stale file detection, and Downloads triage. TRIGGERS - disk space, cleanup, 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

# Disk Hygiene

> Audit disk usage, clean developer caches, find forgotten large files, and triage Downloads on macOS.

> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

## When to Use This Skill

Use this skill when:

- User asks about disk space, storage, or cleanup
- System is running low on free space
- User wants to find old/forgotten large files
- User wants to clean developer caches (brew, uv, pip, npm, cargo)
- User wants to triage their Downloads folder
- User asks about disk analysis tools (dust, dua, gdu, ncdu)

## TodoWrite Task Templates

### Template A - Full Disk Audit

```
1. Run disk overview (df -h /System/Volumes/Data && major directories)
2. Audit developer caches (uv, brew, pip, npm, cargo, rustup, Docker)
3. Scan in-repo build artifacts (Rust target/, .venv, node_modules — often the biggest, see Phase 2.5)
4. Scan for forgotten large files (>50MB, not accessed in 180+ days)
5. Present findings with AskUserQuestion for cleanup choices
6. Execute selected cleanups
7. Report space reclaimed
```

How to install

The exact contents, by fingerprint
mdr add terrylica/cc-skills/disk-hygiene@sha256:7edb344694e7aafb

The line at the top of this page pins the label git:20261105.a12672a, 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.
