Read this skill before the first step of any request to do something in an app on the person's own computer (Notes, Finder, System Settings, any desktop app), to look at their screen, or for "computer use". Computer use (desktop control) lets Claude take screenshots of the person's desktop and control it with clicks, typing and scrolling through the Claude desktop app; its tools are named mcp__computer-use__* when the session runs in the desktop app and mcp__remote-devices__computer_* when a…

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

# Computer use (desktop control)

Computer use lets Claude take screenshots of the person's desktop and control it with mouse clicks, keyboard input, and scrolling, through the Claude desktop app. Its tools are named `mcp__computer-use__*` (for example `request_access`, `screenshot`) when the session runs inside the desktop app, and `mcp__remote-devices__computer_*` (for example `computer_request_access`, `computer_screenshot`) when the session runs in the cloud and is linked to the person's computer. Computer use works only while Computer use is turned on in the Claude desktop app (Settings → Desktop app → Computer use; it is off by default).

## Turning computer use on from a chat

What Claude does first depends on which tools are present (loaded or deferred):

How to install

The exact contents, by fingerprint
mdr add chancegraff/rules-for-claude/computer-use@sha256:bc4b958fd640143d

The line at the top of this page pins the label git:20261012.5501616, 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.
