disk-usage
Skill1 starsChanged 7 months agoMITView on GitHub
This skill should be used when the user asks to "check disk usage", "is my drive full", "what's using my disk", "disk space", "free up space", or mentions low storage. Reports free space, largest directories, caches, Time Machine local snapshots, Xcode simulator footprint, and node_modules sizes, then writes a JSON result to ~/.mac-guardian/data/.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
4 rules. 0 are common, 2 are distinctive, and 2 are very specific to this project.
0
Common
Most of the 3 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 46
When invoked by daily-health-report, return JSON path only.
- Distinctive: line 50
Read-only. Never delete caches, snapshots, DerivedData, or node_modules.
- Distinctive: line 51
If the user asks to clean up after seeing the report, explain what the commands would be and prompt for confirmation.
- Very specific: line 52
Do not call sudo.
“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
disk-usage
Surveys storage usage on macOS without deleting anything.
When to invoke
Trigger on phrases like: "check disk usage", "is my drive full", "what's using my disk", "disk space", "free up space".
What to check
1. Per-volume free space — df -h. Filter to apfs and hfs volumes. For each volume:
/free ≥ 20 GB or ≥ 15%:ok./free 10–20 GB or 5–15%:info./free 5–10 GB or 2–5%:warn./free < 5 GB or < 2%:critical.
2. Top 20 home directories by size — du -shx ~/* 2>/dev/null | sort -rh | head -20. Record as raw. Individual dirs ≥ 50 GB get an info finding.
3. Library caches — du -shx ~/Library/Caches 2>/dev/null. If ≥ 20 GB, info "Library caches at <size>".
4. System / user log sizes — du -shx ~/Library/Logs /private/var/log 2>/dev/null. Record in raw.
5. Time Machine local snapshots — tmutil listlocalsnapshots / 2>/dev/null. Report the count. ≥ 10 snapshots: info.
6. Xcode / iOS simulator footprint — du -shx ~/Library/Developer/CoreSimulator/Devices ~/Library/Developer/Xcode/DerivedData ~/Library/Developer/Xcode/iOS\ DeviceSupport 2>/dev/null. Sum ≥ 30 GB: info. Sum ≥ 100 GB: warn.
7. node_modules across common dev roots (optional and guarded) — only run when the user's home has a Develop/ or Projects/ or code/ directory: find ~/Develop ~/Projects ~/code -type d -name node_modules -maxdepth 6 -prune -exec du -shx {} + 2>/dev/null | sort -rh | head -20. Guard this with a soft timeout (use timeout 60s if gtimeout or coreutils timeout is available; otherwise include only if find completes within reason, and skip with an info finding "skipped — search would take too long" if not).
8. Large Downloads / Trash — du -shx ~/Downloads ~/.Trash 2>/dev/null. Each ≥ 10 GB: info.
Output contract
Standard envelope. Write to ~/.mac-guardian/data/disk-usage-<ISOdate>.json.
Top-level severity = max across all checks. Summary example: "44 GB free on / (warn). Biggest: ~/Library/Caches 38 GB, DerivedData 27 GB."
Handoff
- On direct invocation:
bash ${CLAUDE_PLUGIN_ROOT}/scripts/render-single.sh disk-usage. - When invoked by
daily-health-report, return JSON path only.
Safety
- Read-only. Never delete caches, snapshots, DerivedData, or node_modules.
- If the user asks to clean up after seeing the report, explain what the commands would be and prompt for confirmation.
- Do not call
sudo.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
