What problem does it solve? Manually clicking through a site to verify a deployment or reproduce a bug is slow and hard to document. This Skill drives a persistent headless Chromium browser so an AI agent can navigate pages, fill forms, click elements, capture annotated screenshots, and collect bug evidence automatically. ## Core Features & Use Cases - Interactive QA flows: Navigate to any URL, snapshot interactive elements, fill forms, click buttons, and diff page state before and after each action. - Visual evidence capture: Take full-page, element-level, region-cropped, and annotated screenshots, plus responsive layout captures at mobile, tablet, and desktop viewports. - Deployment verification: Check page text, console errors, failed network requests, and element visibility to confirm a production deploy works. - Use Case: After shipping a login feature, ask the agent to open the staging site, fill in test credentials, submit the form, verify the dashboard appears, and save an annotated screenshot as bug or success evidence. ## Quick Start Ask the agent to open your staging site in the gstack browser, walk through the login flow with test credentials, and screenshot the result.
