Two browser automation integrations in one skill. Chrome DevTools MCP runs immediately for testing, debugging, and performance tracing with Core Web Vitals. Claude-in-Chrome extension (requires --chrome flag) handles authenticated workflows like Google Docs or Gmail and can record GIFs up to 100 frames. Use DevTools for public sites and technical analysis, Claude-in-Chrome when you need to stay logged in or capture demos. The decision tree is straightforward: if you're testing or measuring performance, DevTools. If you're automating tasks in apps where you're already signed in, Claude-in-Chrome. Both have full element interaction, screenshots, and network inspection, but DevTools gives you device emulation and deeper performance analysis while Claude-in-Chrome gives you session persistence and visual recording.
