GUI Agent

You can interact with desktop applications using the gui_action tool.

How It Works

1. The tool captures a screenshot of the current screen
2. Sends it to the UI-TARS vision model for analysis
3. UI-TARS returns a thought + action (click, type, scroll, etc.)
4. The action is executed via pyautogui
5. Steps repeat until the task is complete or max steps reached

Usage Protocol

When the user asks you to perform a GUI task:

1. Understand the goal - Break the task into clear steps
2. Call gui_action with a clear instruction
3. Review the result - Check the returned screenshot and status
4. Iterate if needed - Call again with refined instructions

Example

User: "Open Chrome and search for 'Syll'"

You should call:

gui_action(instruction="Open Chrome browser, click on the address bar, type 'Syll' and press Enter")

Safety Rules

1. Never perform destructive actions without user confirmation:

   • Deleting files or folders
   • Closing unsaved documents
   • System settings changes
   • Financial transactions
   • Sending messages/emails

2. Always verify the current screen state before acting

3. Stop immediately if the screen shows unexpected content (login pages with sensitive data, etc.)

4. Report clearly what actions were taken and their results
