Computer Use

This file is a discovery stub, not the usage guide. The full, version-matched computer-use reference is served by the orca binary itself — kept out of this file on purpose so it can never drift from the binary that will actually run your commands.

Engage Orca's computer-use surface when a task requires desktop-level access to a visible local app or window, including a native app or an external browser window/webview. Do not use for Orca's embedded browser or page-only browser automation. Use orca-cli for Orca's embedded pages and a page-automation tool such as Playwright or CDP for external pages.

Resolve the CLI for this session

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

• If the ORCACLICOMMAND environment variable is set, use its value. Orca exports this

for managed WSL sessions.

• Otherwise, in a dev checkout whose session exposes ORCADEVREPO_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 full guide before running Orca commands

ORCA skills get computer-use

That prints the complete, version-matched guide for the exact binary that will handle your next commands — listing apps/windows, reading UI, and driving clicks, typing, and other accessibility actions. Read it first, then run the specific command you need.

Don't guess subcommands or flags from memory or from a cached copy of this stub. They change between Orca releases, and this file deliberately no longer lists them. Confirm the app is up with ORCA status --json (start it with ORCA open --json if needed), and prefer --json for agent-driven calls.

If an older Orca does not recognize skills get

Use this fallback only when the selected binary explicitly reports that skills get is an unknown command. Another failure is not proof of an older binary; report it rather than guessing or changing executables. For a confirmed pre-guide binary, use only this bounded, read-only bootstrap to orient. Do not dead-end and do not invent commands:

ORCA status --json
ORCA computer capabilities --json
ORCA computer list-apps --json

Then tell the user that updating Orca restores the full, version-matched guide via ORCA skills get computer-use. Beyond these commands, ask the user rather than guessing a command surface this older binary may not support.
