Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00530 |
| Opus 5.5 | $0.00008 | $0.00212 |
| Sonnet 5.5 | $0.00004 | $0.00106 |
| Haiku 4.5 | $0.00002 | $0.00053 |
Grade A, and why
cleanup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cleanup — reclaim space without breaking anything
Read ${CLAUDE_PLUGIN_ROOT}/skills/it-core/SKILL.md first — the safety contract is binding, especially: Trash never rm, only the user empties the Trash, dry-run first. Read ~/ITGuy/machine.md if it exists. If uname is not Darwin, say this version supports Mac only and stop.
Step 1: Scan (changes nothing)
Record free space now (df -h /). Dispatch the mac-it-guy-pro:janitor agent (via Task) in scan mode across all its categories: app caches, old downloads, large stale files, duplicates, developer leftovers, Trash size.
Step 2: Present findings and let the user choose
Show the janitor's candidate table (Category | Items | Size | Risk) in plain language. Then use AskUserQuestion (multiSelect) to pick categories to clean. Rules:
- Large stale files and duplicates are never offered as a bulk category — if selected, walk through them item by item (or group by group) with an explicit keep/Trash choice per item.
- If total reclaimable space is under 1 GB, say cleanup isn't worth it right now and show what's actually using the disk instead (top
dufolders).
Step 3: Execute the approved list only
Dispatch the janitor in execute mode with the exact approved categories/paths. Nothing outside the approved list moves — no matter how obviously junk it looks.
Step 4: Report and log
- Before/after free space from
df -h /, and the total now sitting in the Trash. - Close with: emptying the Trash in Finder is what makes the space real, and that step is the user's.
- Append the visit line to
~/ITGuy/visits.log. If disk pressure was on the profile's Watch List, update it with today's numbers.
Errors
- Locked or permission-blocked files → report each with a plain-language cause; never force.
- The guard hook blocks an rm → that is the contract working; the janitor must use the Trash recipe. If it happens, note it and continue via Trash.
- User approves nothing → fine; report the scan findings as a reference and log the visit as scan-only.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cleanup is a command published in the GitHub repository xiaolai/mac-it-guy-pro (6 stars, last pushed 16d ago), licensed MIT. It adds 21 tokens to every session and 530 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
