+### URL Reporting
+
+The Gemini Computer Use API requires a URL in all function responses. However, the Kernel Computer Controls API doesn't provide a method to retrieve the current page URL.
+
+As a workaround, this template reports `about:blank` as the URL in all responses. This works because Gemini primarily uses the screenshot to understand page state - the URL is a required field but not critical for functionality.
