A specialized skill for controlling and inspecting a live Chrome browser. This skill leverages the chrome-devtools MCP server to perform a wide range of browser-related tasks, from simple navigation to complex performance profiling.

The snapshot provides uid values required by interaction tools.list_console_messages) and network requests (list_network_requests).performance_start_trace and performance_analyze_insight to identify LCP issues or layout shifts.Use this skill when:
new_page: Open a new tab/page.navigate_page: Go to a specific URL, reload, or navigate history.select_page: Switch context between open pages.list_pages: See all open pages and their IDs.close_page: Close a specific page.wait_for: Wait for specific text to appear on the page. Use reasonable timeouts.click: Click on an element (use uid from snapshot).fill / fill_form: Type text into inputs or fill multiple fields at once.hover: Move the mouse over an element.press_key: Send keyboard shortcuts or special keys (e.g., "Enter", "Control+C").drag: Drag and drop elements.handle_dialog: Accept or dismiss browser alerts/prompts.upload_file: Upload a file through a file input.take_snapshot: Get a text-based accessibility tree (best for identifying elements).take_screenshot: Capture a visual representation of the page or a specific element.list_console_messages / get_console_message: Inspect the page's console output.evaluate_script: Run custom JavaScript in the page context.list_network_requests / get_network_request: Analyze network traffic and request details.resize_page: Change the viewport dimensions.emulate: Throttling CPU/Network or emulating geolocation.performance_start_trace: Start recording a performance profile.performance_stop_trace: Stop recording and save the trace.performance_analyze_insight: Get detailed analysis from recorded performance data.new_page: Open a new tab/page.navigate_page: Go to a specific URL, reload, or navigate history.select_page: Switch context between open pages.list_pages: See all open pages and their IDs.close_page: Close a specific page.wait_for: Wait for specific text to appear on the page.click: Click on an element (use uid from snapshot).fill / fill_form: Type text into inputs or fill multiple fields at once.hover: Move the mouse over an element.press_key: Send keyboard shortcuts or special keys (e.g., "Enter", "Control+C").drag: Drag and drop elements.handle_dialog: Accept or dismiss browser alerts/prompts.upload_file: Upload a file through a file input.take_snapshot: Get a text-based accessibility tree (best for identifying elements).take_screenshot: Capture a visual representation of the page or a specific element.list_console_messages / get_console_message: Inspect the page's console output.evaluate_script: Run custom JavaScript in the page context.list_network_requests / get_network_request: Analyze network traffic and request details.resize_page: Change the viewport dimensions.emulate: Throttling CPU/Network or emulating geolocation.performance_start_trace: Start recording a performance profile.performance_stop_trace: Stop recording and save the trace.performance_analyze_insight: Get detailed analysis from recorded performance data.Always prefer take_snapshot over take_screenshot for finding elements. The snapshot provides uid values which are required by interaction tools.
1. `take_snapshot` to get the current page structure.
2. Find the `uid` of the target element.
3. Use `click(uid=...)` or `fill(uid=..., value=...)`.
When a page is failing, check both console logs and network requests.
1. `list_console_messages` to check for JavaScript errors.
2. `list_network_requests` to identify failed (4xx/5xx) resources.
3. `evaluate_script` to check the value of specific DOM elements or global variables.
Identify why a page is slow.
1. `performance_start_trace(reload=true, autoStop=true)`
2. Wait for the page to load/trace to finish.
3. `performance_analyze_insight` to find LCP issues or layout shifts.
list_pages and select_page if you are unsure which tab is currently active.uid values may change.wait_for to avoid hanging on slow-loading elements.take_screenshot sparingly for visual verification, but rely on take_snapshot for logic.
