Quick start

    • pnpm tsx skills/browser-tools/scripts/browser-tools.ts start --profile
  2. Navigate:
    • pnpm tsx skills/browser-tools/scripts/browser-tools.ts nav https://example.com
  3. Screenshot:
    • pnpm tsx skills/browser-tools/scripts/browser-tools.ts screenshot

Common commands

  • start Launch Chrome with --remote-debugging-port and optional profile copy.
  • nav <url> Navigate current tab (or --new).
  • eval <code...> Run JS in page context (supports async).
  • screenshot Capture viewport to a temp PNG path.
  • pick <message...> Interactive DOM element picker.
  • console Stream console logs (filters, follow mode).
  • cookies Dump cookies as JSON.
  • search <query...> Google search in Chrome; optional readable content.
  • content <url> Readability extraction to markdown-like text.
  • inspect List DevTools-enabled Chrome processes + tabs.
  • kill Terminate DevTools-enabled Chrome processes.
