What problem does it solve? Verifying frontend changes and testing web UI interactions manually is slow and error-prone. This Skill lets an AI agent drive a real browser to open pages, inspect the accessibility tree, fill forms, click elements, and capture screenshots for verification and debugging. ## Core Features & Use Cases - Accessibility-Tree Snapshots: Get interactive element refs (@e1, @e2) to precisely target clicks, fills, and selections without brittle selectors. - Form & Flow Testing: Fill inputs, select dropdowns, check checkboxes, and click buttons to verify complete user flows end to end. - Screenshots & Debugging: Capture viewport or full-page screenshots, view console logs and page errors, highlight elements, and run JavaScript with eval. - Use Case: After modifying a frontend page, open the local dev server, snapshot the interactive elements, fill and submit a form, then screenshot the result to confirm the change renders correctly. ## Quick Start Open http://localhost:4321 in the browser, take an interactive snapshot, and verify the page renders correctly with a screenshot.
