Diagnose and fix slow Mac, Windows or Linux performance, and reclaim disk from developer caches. Use this skill whenever the user says their computer, laptop, Mac, MacBook, PC, Windows machine, Linux box, Ubuntu or Fedora install is slow, sluggish, laggy, freezing, stuttering, overheating, beachballing, hanging, or whenever the fans are spinning loudly. Also trigger when the user asks to "clean up", "speed up", "tune up", "optimize", "fix", "declutter", or "make faster" their computer or laptop.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# janitor-device

A guided speed audit and cleanup for macOS, Windows and Linux. Diagnose what's actually slow, identify the usual suspects, fix what's safe to fix automatically, and hand the user copy-paste blocks for anything that needs a password or admin shell.

## How to use this

You don't need to remember any commands. The skill triggers automatically when you describe your problem:

> "my mac is slow"
> "my pc is laggy and the fans won't shut up"
> "clean up my laptop please"
> "why are my fans spinning so much"
> "my battery drains in two hours"
> "ubuntu got sluggish after the upgrade"
> "my disk is full and I don't know why"
> "/janitor-device"

Claude runs diagnostics, shows you what's wrong in plain language, asks permission, then fixes what it can automatically and gives you copy-paste blocks for anything that needs a password. Everything is reversible: files go to Trash or Recycle Bin, disabled apps just get renamed, masked or flagged as disabled. You can undo any of it.

How to install

The exact contents, by fingerprint
mdr add arshiaecho/janitor/janitor-device@sha256:0ba78ace6016e6f2

The line at the top of this page pins the label git:20261104.db9f76f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
