UI Preview Skill

Preview local dev servers URLs using Chrome DevTools.

Available Tools

• navigate_page - Navigate to a URL (supports url, back, forward, reload)
• new_page - Open a new browser tab and load a URL
• list_pages - Get a list of pages open in the browser
• select_page - Select a page as context for future tool calls
• click - Clicks on the provided element (supports double click)
• fill - Type text into an input, text area, or select an option from a <select> element
• hover - Hover over the provided element
• press_key - Press a key or key combination. Use this when other input methods like fill() cannot be used (e.g., keyboard shortcuts, navigation keys, or special key combinations)
• handle_dialog - If a browser dialog was opened, use this command to handle it (accept/dismiss)
• wait_for - Wait for the specified text to appear on the selected page
• take_snapshot - Take a text snapshot of the currently selected page based on the a11y tree. The snapshot lists page elements with unique IDs
• take_screenshot - Take a screenshot of the page or element
• evaluate_script - Evaluate a JavaScript function inside the currently selected page. Returns the response as JSON so returned values have to be JSON-serializable
• list_console_messages - List all console messages for the currently selected page since the last navigation
• get_console_message - Gets a console message by its ID

Workflow

• Navigate to the target URL using navigate_page
• Wait for the desired element to appear using wait_for
• Take a snapshot of the page structure using take_snapshot
• Interact with elements using click, fill, hover, or press_key
• Handle any dialogs using handle_dialog
• Screenshot the page using take_screenshot
• Inspect console logs using list_console_messages / get_console_message
