List all active devices connected to the server. Returns device ID, name, OS, type, screen resolution and host info. Call this first to get the device_id required by take_screenshot, run_task, and other device tools.

List available model aliases (e.g. 'balanced', 'high-quality'). Use the alias name as the model_alias parameter in run_task.

Capture a live screenshot of the device's current screen. Returns the image directly (synchronous, up to 30s).

Use this tool when:

• You need to see what is currently displayed on the device screen.

• You want to verify the result after a run_task completes.

• You need to inspect the UI before deciding what action to take.

This returns the real-time screen.

Perform UI automation on a device. The AI agent automatically handles app launching, screen interactions (tapping, swiping, typing, navigating), and multi-step workflows.

Use this tool for:

• Opening apps and performing tasks: 'open Chrome and search for weather'

• In-app interactions: tapping, swiping, typing, navigating

• Content engagement: liking, commenting, sharing, following, subscribing

• Information gathering: reading screen content, searching, extracting data

• Web browsing: visiting URLs, filling forms, clicking links

• Messaging: sending messages, replying, forwarding

Do NOT use this tool to only take a screenshot — use take_screenshot instead.

Provide only the end goal in instruction (e.g., 'open WeChat and send hello to Zhang San'), not low-level steps. Returns immediately with a task ID. Use get_task to poll for status and results. After completion, call take_screenshot to verify the result.

Get the status and step details of a task started by run_task.

Returns current status and all completed steps with action type, AI decision, params, and output. Possible status values: pending, running, succeeded, failed, cancelled, timeout, partially_succeeded. If status is 'pending' or 'running', poll again (recommended interval: 2-3 seconds).

Screenshots are not included in the response — use take_screenshot after completion to verify the result.

Cancel a task that is currently in 'pending' or 'running' status. Has no effect on tasks that have already completed (succeeded, failed, timeout).
