Safely reclaim disk space on macOS without touching personal or agent data. Use when the user asks to free disk space, clear caches, or investigate a nearly full Mac.

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. About 0 are common, 2 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈2
Distinctive · estimate
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 15
Never inspect, delete, or modify the data of the IDE or agent you're running inside — its application-support dir, caches, globalStorage, …
- Distinctive: line 20
Never delete browser history, extensions, cookies, credentials, local storage, IndexedDB, bookmarks, passwords, or user-created files.
- Distinctive: line 22
Ask before destructive cleanup such as deleting Docker images, containers, volumes, or virtual disks.
- Very specific: line 45
Do not represent the sealed / system volume as the Mac's usable data-volume capacity.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Free Disk Space
Investigate first. Delete only regenerable data the user has authorized.
Safety
- Never inspect, delete, or modify the data of the IDE or agent you're running
inside — its application-support dir, caches,
globalStorage, databases, extensions, or logs — unless the user explicitly names it as a cleanup target. On macOS that lives under~/Library/Application Support/<app>/(e.g..../Cursor/). - Never delete browser history, extensions, cookies, credentials, local storage, IndexedDB, bookmarks, passwords, or user-created files.
- Ask before destructive cleanup such as deleting Docker images, containers, volumes, or virtual disks.
Workflow
Record current usage from the macOS data volume:
df -h /System/Volumes/Data- Find the largest consumers before deleting anything. Use
du, package manager diagnostics, and application-specific storage commands. Do not descend into protected agent/IDE data. - Explain what is large, whether it is regenerable, and the expected impact.
- Clean only safe targets:
- contents of
~/Library/Caches/ - unused package-manager cache entries, such as
pnpm store prune - known browser model/GPU caches, never browser profile data
- contents of
- For sparse files such as Docker's virtual disk, report actual disk use from
du, not apparent size fromls. - Record usage again and report space freed.
Do not represent the sealed / system volume as the Mac's usable data-volume
capacity.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
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.
