What problem does it solve? Starting a dev server does not guarantee the page actually works — blank pages, hydration errors, missing environment variables, and broken imports only appear in the browser. This Skill automates a visual and console-level verification pass so failures are caught before continuing development. ## Core Features & Use Cases - Automated Page Verification: Opens the dev server URL with agent-browser, waits for network idle, screenshots the page, and checks for blank content or error overlays. - Error Detection: Detects Next.js, Vite, and webpack error overlays plus console errors via browser evaluation commands. - Hang Diagnosis: Correlates stuck spinners and frozen pages with server-side evidence from Vercel logs and Workflow DevKit run inspection. - Use Case: After running next dev, automatically verify the page loads, confirm no console errors exist, and screenshot the result before proceeding with feature work. ## Quick Start Start my dev server and verify the page loads correctly in the browser with a screenshot and console error check.
