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 whenever you must inspect or operate a local desktop app window — reading its accessibility tree, taking screenshots, or performing safe UI actions (click controls, type, press keys, scroll, drag, set values). It also covers browser windows, webviews, and Orca's own UI. Triggers include "computer use", "orca computer", "read Spotify", "read Slack", "control/click/read in a desktop app", and "get app state".

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.
