computer-use

Use it when: a task needs a desktop app's or browser window's interface, and no command, file or API can do it
It does: clicks, types, opens menus, answers dialogs and takes screenshots in native apps and outside browser windows such as Chrome, Edge or Safari
Needs: Orca, Stably's desktop app for working with many coding agents in parallel, installed; it starts Orca if it isn't running
Unlike orca-cli: which drives the browser built into Orca, this works on other windows on your screen

TLDR

It gives an agent a way to work with apps that only have a graphical interface. Through the orca computer command, the agent reads a visible window as its accessibility tree, the structured list of buttons, fields and menus that screen readers use, then clicks, types, picks menu items, answers dialogs and takes screenshots. The SKILL.md itself is a short stub: it has the agent load the guide that matches the installed Orca version, so the instructions follow the app. It tells the agent to prefer the shell, files, git, HTTP or an existing CLI whenever one of those can do the job, and to reach for the interface only when nothing else can. It also guards against a Linux pitfall: outside Orca's own terminals, a bare orca command usually starts the GNOME screen reader of the same name.

Frontmatter

name: computer-use
description: >-
  Drives the GUI of a visible local app window through `orca computer`: accessibility
  tree, clicks, typing, menus, dialogs, and screenshots in native apps and external
  browser windows (Chrome, Edge, Safari) or webviews. Prefer a programmatic path
  (shell, filesystem, git, HTTP, existing CLIs) whenever it can complete the task.
  Use only when a visible window needs GUI control those cannot reach. Do not use
  for Orca's embedded browser (`orca-cli`).

Computer Use

This discovery stub loads the version-matched guide from the Orca executable used for this session.

Resolve the CLI for this session

Choose the executable once and reuse it for every later command:

If the ORCA_CLI_COMMAND environment variable is set, use its value. Orca exports this for managed WSL sessions.
Otherwise, in a dev checkout whose session exposes ORCA_DEV_REPO_ROOT, use orca-dev.
Otherwise, on Linux outside an Orca-managed terminal, use orca-ide. Never run bare orca there — outside Orca's terminals it normally resolves to the GNOME Orca screen reader (/usr/bin/orca) and starts speech on the user's machine.
Otherwise, use orca.

Below, ORCA is a placeholder for the executable you resolved. Substitute it before running anything; do not create a shell variable or run ORCA literally. This works the same way in POSIX shells, PowerShell, and cmd.exe.

If the selected executable cannot run, report its exact error and stop. Do not fall through to another executable, which could silently target a different Orca build.

Load the version-matched guide before running Orca commands

ORCA skills get computer-use

Prefer --json. Use the selected executable's --help for commands or flags the guide does not cover. If a command reports that Orca is not running, start it with ORCA open --json and retry. If it fails with runtime_access_denied, your sandbox blocked the connection: re-run it with escalated permissions, and do not run ORCA open or restart Orca. If skills get is unknown, explain that updating Orca restores the guide; use --help for read-only discovery and do not guess unsupported commands.
