What problem does it solve? Manually verifying that a web page loads correctly, that a user flow works end to end, or that a deployment matches staging requires repetitive clicking and visual checking. This Skill automates that work by driving a persistent headless Chromium browser through simple commands, producing snapshots, diffs, and annotated screenshots as evidence. ## Core Features & Use Cases - Page and flow verification: Navigate any URL, fill forms, click elements, and assert element states (visible, enabled, checked, focused) to validate user flows like login or checkout. - Visual evidence and diffs: Capture annotated screenshots with labeled element refs, take responsive screenshots at mobile/tablet/desktop viewports, and diff page state before and after actions or between two environments. - Diagnostics and handoff: Inspect console errors, network requests, cookies, and storage, and hand off to a visible Chrome window when hitting CAPTCHAs or multi-factor auth. - Use Case: After deploying a new feature, ask the agent to open the staging URL, walk through the signup flow, verify the dashboard appears, and produce an annotated screenshot plus console log as a bug report. ## Quick Start Ask the agent to open your site in the browser, test the login flow, and take an annotated screenshot of the result.
