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 you a fast headless browser (~100ms per command after startup) to navigate pages, interact with elements, capture evidence, and assert page state without writing test scripts. ## Core Features & Use Cases - Page Verification: Navigate any URL, read page text, inspect console errors and network failures, and assert element states (visible, enabled, checked, focused). - Interactive Flow Testing: Fill forms, click elements, upload files, handle dialogs, and diff page state before and after actions with unified snapshots. - Visual Evidence: Take annotated or plain screenshots, capture responsive layouts across mobile/tablet/desktop viewports, and render retina-scale images for bug reports. - Use Case: After deploying a new login flow, navigate to the page, fill credentials, submit, diff the resulting DOM, and capture an annotated screenshot proving the dashboard renders — all in seconds. ## Quick Start Ask the AI to open your staging site in the browser, fill in the login form, and take a screenshot of the dashboard to verify the deploy worked.
