Agent Desktop

agent-desktop

Use this skill when the task involves the host macOS desktop rather than repository files, shell output, or browser-only verification.

This project uses agent-desktop on the host. Prefer the built-in Computer sub-agent for these tasks instead of trying to drive the desktop with plain shell commands.

When to use it

• The user wants to inspect or interact with a native macOS application.
• The task needs app launch, window focus, accessibility snapshots, semantic element refs, clicks, typing, keypresses, or scrolling.
• A browser-only workflow is not enough, or the target is not a web page.

Requirements

• agent-desktop must be installed and its native binary available.
• On macOS, the terminal app running grok needs Accessibility permission.
• Refs from computer_snapshot are only valid until the next snapshot.

Preferred flow

1. Delegate to task with agent: "computer" unless the current agent already has the computer_* tools and the task is tiny. 2. Use computer_launch, computer_list_windows, or computer_focus_window to get the target app/window ready. 3. Start with computer_snapshot. 4. Pick one ref-based action. 5. After any UI transition, snapshot again before reusing refs.

Tool guidance

• computer_snapshot: primary observation tool; prefer interactive_only.
• computer_click: use ref values from the latest snapshot whenever possible.
• computer_type: requires a target ref and is preferred over coordinate typing.
• computer_press: use for shortcuts and special keys such as Enter, Tab, cmd+space, or cmd+k.
• computer_scroll: pass an element ref, not raw coordinates.
• computer_get: read text, value, bounds, role, or states from a ref.
• computer_screenshot: use for visual confirmation or when the accessibility tree is not enough.

Reliability rules

• Use a snapshot -> act -> snapshot loop.
• Prefer refs over coordinates.
• Refs go stale after the next snapshot; do not reuse them blindly.
• Keep actions reversible and low risk unless the user explicitly asked for something destructive.
• If the accessibility tree is poor or ambiguous, use computer_screenshot for confirmation and explain the limitation.

Blockers

Stop and report clearly if:

• Accessibility permission is missing.
• agent-desktop is unavailable or its native binary is missing.
• The target app/window cannot be found.
• Refs are stale or ambiguous after a UI transition.
• The requested action could be destructive and the user did not explicitly ask for it.
