What problem does it solve? Manually verifying that a web page loads correctly, a form submits, or a deployment looks right is slow and error-prone. This Skill gives an AI agent a persistent headless Chromium browser so it can navigate URLs, interact with elements, capture screenshots, and assert page state as evidence for QA and dogfooding. ## Core Features & Use Cases - Interactive page control: Navigate URLs, fill forms, click elements, handle dialogs, upload files, and diff page snapshots before and after actions. - Visual evidence capture: Take plain or annotated screenshots, responsive layout captures across mobile/tablet/desktop, and retina-scale renders for bug reports. - State assertions and diagnostics: Check visibility, enabled/disabled state, console errors, and failed network requests, plus compare staging versus production environments. - Use Case: After deploying a login flow, ask the agent to open the site, fill in credentials, submit the form, diff the resulting page, and attach an annotated screenshot proving the dashboard rendered. ## Quick Start Ask the agent to open your staging site in the browser, test the signup flow, and take an annotated screenshot of the result.
