disk-hygiene skillB
disk-hygiene is agent-read markdown (skill) from terrylica/cc-skills: macOS disk cleanup, cache pruning, stale file detection, and Downloads triage. TRIGGERS - disk space, cleanup, disk usage.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# 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 ``` …
