Computer Use

Use this skill for desktop UI through orca computer. When the requested target is a website or web app, operate the desktop browser app/window that contains the page.

Preconditions

• Choose the Orca executable once: use the ORCA_CLI_COMMAND environment value when set; otherwise use orca-dev in a dev session exposing ORCA_DEV_REPO_ROOT, orca-ide on Linux outside an Orca-managed terminal, and orca everywhere else. Never try bare orca first on unmanaged Linux because it normally resolves to the GNOME screen reader.
• In every command example, ORCA is a documentation placeholder — including examples that name a specific shell. Replace it with that chosen executable before running the command; do not create a shell variable or run ORCA literally. Blocks that name no shell are intentionally shell-neutral for POSIX shells, PowerShell, and cmd.exe.
• Prefer --json. Screenshot bytes are omitted from JSON and written to screenshot.path.
• Do not push, submit forms, send messages, buy items, delete data, change account settings, or expose secrets unless the user explicitly asked for that action.
• If an app contains sensitive content, read only what the user requested.
