computer tool. Use for anything a browser tab cannot reach (Office, IDEs, installers, system dialogs, legacy apps). Safety first, one action per screenshot.\nmetadata: {\"navin\":{\"emoji\":\"\uD83D\uDDA5️\",\"category\":\"navigation\"}}The built-in computer tool gives the agent the same reach as the person in front\nof the machine: a screenshot of the real display, a mouse, a keyboard. It is off by\ndefault; navin computer enable (or tools.computer.enabled: true) turns it on and\nnavin computer doctor tells what the host still needs.
Prefer the browser tool for web pages (faster, DOM refs, no risk to the desktop).\nReach for computer when the target is a native window, a system dialog, a file\npicker, an installer, or a site that only works in the user's own browser profile.
