computer-use is agent-read markdown (skill) from clacky-ai/openclacky: Drive the macOS desktop when a task needs a native app, dialog, menu bar, file picker or anything the terminal and browser tools cannot reach. Screenshot first, then click and type by coordinates read from that image..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Computer Use (macOS)
GUI control goes through the script bundled with this skill. The `computer-use` extension is
off by default, so if you are reading this the user has switched it on.
## When to use it
- Native apps, dialogs, menu bars, installers, file pickers, System Settings.
- Anything on screen that `terminal` cannot reach and `browser` cannot automate.
- For web automation prefer the `browser` tool while it works. If it fails because remote
debugging is unavailable, fall back here immediately — do not open `chrome://inspect` or run
the browser-setup skill unless the user asks for it.
## Workflow
1. Bring the target app forward if another window may cover it:
```bash
ruby <skill_dir>/bin/computer.rb activate "WorkBuddy"
```
It needs no extra macOS permission. If the name does not match (localized
app names differ), it prints what is actually frontmost — take a screenshot
to see the real window order instead of guessing.
2. Screenshot — with a labelled grid when you will need to click precise spots:
```bash
ruby <skill_dir>/bin/computer.rb screenshot --grid
```
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
