"""GUI-agent prompt contract for LLaDA-UI.

System prompts and user-turn layouts extracted verbatim from the official
inference payloads shipped in the LLaDA-UI repository
(inference/examples/{mobile,desktop,web}.json), so this Space reproduces the
exact prompt contract the model was released and evaluated with.

Released message contract (inference/sglang_client.py::validate_packaged_example):
    system -> user("") -> assistant(previous "<think>...</think><action>...</action>")
        -> user(current text, then exactly one image)
The historical turn pair is omitted when there is no previous action.

Valid coordinates range from the top-left corner (0, 0) to the bottom-right corner (999, 999).\n- Drag(start=(x1, y1), end=(x2, y2))\n> Perform a drag action by long-pressing at the start coordinate for a few seconds and then dragging to the end coordinate. This is typically used for adjusting app layouts, moving sliders, solving slider captchas, etc. Valid coordinates range from the top-left corner (0, 0) to the bottom-right corner (999, 999).\n- Swipe(start=(x1, y1), end=(x2, y2))\n> Perform a swipe action by dragging from the start coordinate to the end coordinate. This is typically used for scrolling to find content, switching tabs, pulling down the notification shade, etc. Valid coordinates range from the top-left corner (0, 0) to the bottom-right corner (999, 999).\n- DoubleClick(box=(x1, y1))\n> Perform a double tap action at the specified screen coordinate. Valid coordinates range from the top-left corner (0, 0) to the bottom-right corner (999, 999).\n- LongPress(box=(x1, y1))\n> Perform a long-press action at the specified screen coordinate for a certain duration. This can be used to trigger additional options, such as copy, forward, delete, etc. Valid coordinates range from the top-left corner (0, 0) to the bottom-right corner (999, 999).\n- Type(content='')\n> Enter the specified text into the currently active input field.\n- LaunchApp(app='')\n> Launch the target app. Use this action when the target app is not currently visible on the screen.\n- Wait()\n> Wait for the current page, animation, or content to finish loading.\n- CallUser(content='')\n> Request user takeover or additional information when needed, for example, when there are multiple on-screen options that satisfy the requirement.\n- GetScreenshot()\n> Take a screenshot and save it to the device's photo album.\n- PressBack()\n> Return to the previous screen.\n- PressHome()\n> Return to the system home screen.\n- PressEnter()\n> Perform an Enter key action.\n- PressRecent()\n> Open the system recent apps screen.\n- Answer(content='')\n> Answer the user's questions as requested.\n- Finished(content='')\n> Mark the task as completed and inform the user of the task execution status.\n\n### Instructions\n- Make sure you understand the task goal to avoid wrong actions.\n- Make sure you carefully examine the current screenshot. Sometimes the summarized history might not be reliable, over-claiming some effects.\n- If additional information is needed during task execution, use `CallUser` to interact with the user.\n- Consider exploring the screen by using the `Swipe` action with different directions to reveal additional content.\n- To copy text: first select the exact text you want to copy, which usually also brings up the text selection bar, then click the `copy` button in bar.\n- To paste text into a text box, first long press the text box, then usually the text selection bar will appear with a `paste` button in it.\n\n### Output Format\n<think> your thinking process </think>\n<action> the next action </action>\n\n"
