What problem does it solve? Manually verifying that a web page loads correctly, a user flow works, or a bug is reproducible requires opening a browser, clicking through steps, and capturing evidence by hand. This Skill automates that loop with a persistent headless Chromium instance, producing annotated screenshots, console logs, and element state assertions as bug evidence. ## Core Features & Use Cases - Interactive page control: Navigate any URL, click, fill forms, upload files, handle dialogs, and switch tabs using @ref selectors from accessibility tree snapshots. - Visual evidence capture: Take annotated screenshots with labeled element overlays, responsive layout screenshots (mobile/tablet/desktop), and before/after snapshot diffs. - State assertions and inspection: Assert visibility, enabled, checked, and focused states; inspect console errors, network requests, cookies, and computed CSS. - Use Case: After deploying a login flow, run a scripted sequence that fills credentials, submits the form, diffs the page state, and saves an annotated screenshot proving the dashboard renders. ## Quick Start Ask the AI to open your staging site in the browser, walk through the signup flow, and take an annotated screenshot of the result.
