macos-cleanup

macos-cleanup is a skill for Claude Code, Codex from pivoshenko/pivoshenko.ai. It costs 150 tokens per session (1,601 once invoked), scanned B, original, MIT.

A macOS cleanup workflow for finding unused caches, logs, app leftovers, backups, development files, and startup items.

In plain words
What is it for?
Use it to scan storage, identify leftovers from deleted apps, review developer-tool caches and login items, remove confirmed files, and verify recovered space.
Why use it?
It shows what is using disk space before anything is removed and separates safe-to-regenerate files from items that need a decision.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

macos-cleanup scanned grade B with 2 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scan.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- No sudo by default. System paths (`/Library/Caches`, `/Library/Logs`, LaunchDaemons) -> report; act only on explicit sudo OK.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Xcode: `rm -rf ~/Library/Developer/Xcode/DerivedData`; `xcrun simctl delete unavailable`; old iOS DeviceSupport = risky (re-fetch needs the device).

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

macOS Cleanup

Deep-clean: junk + app leftovers + dev junk + space/startup audit. Destructive territory -> scan (read-only) -> sized report -> confirm -> delete -> verify freed. Never delete during scan.

Flow

  1. Scan: bash scripts/scan.sh. Read-only, deletes nothing. Sized report -> stdout, raw lists -> /tmp/macos-cleanup-scan.*/ (path printed). du over ~/Library = takes a minute+, warn user up front.
  2. Cross-ref leftovers: installed.txt (app bundle ids + cask/formula names) vs candidates (app-support.txt, containers.txt, preferences.txt, caches.txt, saved-state.txt, LaunchAgents). Matching rules below. Flag only what you can name the dead app for.
  3. Report: table per category — item · size · verdict (safe = regenerable / risky = judgment call / skip + why). Lead with total reclaimable + current disk free.
  4. Confirm: AskUserQuestion, multiSelect across categories. Anything >1 GB or non-regenerable (iOS backups, go modcache, simulator runtimes, Xcode DeviceSupport) -> its own option, never bundled into a category.
  5. Clean: only what was confirmed, commands below. Leftovers + launch agents -> Finder Trash (recoverable). Pure caches -> rm fine.
  6. Verify: df -h / before vs after -> "freed X GB". List skipped + why. df unchanged -> likely APFS purgeable / TM local snapshots; report tmutil listlocalsnapshots /, thinning is automatic, tmutil deletelocalsnapshots <date> only on explicit ask.

Categories

User/system junk (mostly safe)

  • ~/Library/Caches/* — per-entry, not wholesale. Skip entries of currently running apps (pgrep -if <name>) or tell user to quit them.
  • ~/Library/Logs, CrashReporter, QuickLook thumbnails, ~/Library/HTTPStorages — regenerable.
  • Trash: osascript -e 'tell app "Finder" to empty trash' (handles locked files).
  • Mail Downloads cache — safe; Mail data itself off-limits.
  • iOS device backups (~/Library/Application Support/MobileSync/Backup) — user data, not regenerable. Individual confirm, state device + date per backup (ls -lt).

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

macos-cleanup is a skill published in the GitHub repository pivoshenko/pivoshenko.ai (4 stars, last pushed 5d ago), licensed MIT. It adds 150 tokens to every session and 1,601 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
