Chrome Browser

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.

Chrome Browser Automation

Installation

Standalone script: No download; the skill invokes .claude/tools/chrome-browser/chrome-browser.cjs (Node.js v18+ required).

MCP integrations (for full automation):

Chrome DevTools MCP: Usually bundled with the environment; ensure Chrome/Chromium is installed (google.com/chrome).
Claude-in-Chrome: Install the Claude-in-Chrome extension and run with --chrome when needed.

Cheat Sheet & Best Practices

Testing: Test user-visible behavior, not implementation. Isolate tests (own storage/cookies); use before/after hooks for login or setup. Mock third-party networks instead of depending on live services.

DevTools Recorder: Record flows in Recorder panel; export as JSON or test scripts (Puppeteer, Nightwatch). Replay with Puppeteer Replay in CI. Use for performance measurement of user flows.

Hacks: Prefer Chrome DevTools MCP for testing/debugging (always on); use Claude-in-Chrome for authenticated sessions (GIF, forms). Limit GIF frames (e.g. 100) to avoid memory issues. Use take_snapshot for structure; evaluate_script for custom checks.
