Argus hooks Chrome DevTools Protocol to run full QA sweeps on web apps without writing test scripts. It exposes six tools: argus_audit for fast scans (JS errors, network failures, a11y, SEO, security), argus_audit_full for deep passes with Lighthouse scoring and memory leak detection, argus_compare to diff dev against staging with side-by-side screenshots, and argus_get_context to snapshot everything broken on the current tab for Claude to diagnose. You launch Chrome with remote debugging on port 9222, point it at your local or staging URL, and ask Claude to run an audit. Reports post to Slack or generate a standalone HTML dashboard. Built for catching runtime exceptions, API double-fetch bugs, CSS cascade conflicts, and responsive layout regressions before they ship.
