What problem does it solve? Verifying what a web page actually renders and measures—contrast ratios, console errors, network failures, WebSocket traffic—requires a real browser, and guessing from code or screenshots leads to false conclusions. This Skill drives a real browser (locally or in a container) to observe and measure pages objectively, including authenticated pages and real-time socket traffic. ## Core Features & Use Cases - Page inspection with measurement: Renders a page and returns computed contrast ratios with WCAG verdicts, console errors, served scripts, and timestamped screenshots via inspect.mjs. - Probe families: Optional audits for accessibility (axe-core), rendering overflow, network, Web Vitals performance, storage, and responsive breakpoints, each returning bounded OK/ALERTE verdicts. - Real-time observation: watch.mjs records WebSocket frames and HTTP errors over time; socket.mjs drives an application socket end-to-end from within the page with its real cookies and origin; audit.mjs runs Lighthouse including an agentic-browsing category. - Use Case: After fixing a color palette in an admin console, run the inspection script against the page in both light and dark themes to confirm the contrast ratio meets WCAG AA before shipping. ## Quick Start Ask the agent to open the page at /nodefony/login in a driven browser and report its console errors, contrast measurements, and a screenshot.
