Browser Automation Skill

Profile

  • Use profile: openclaw for all automated browsing
  • Browser is managed by OpenClaw gateway

Core Patterns

Navigation

  • Use browser navigate with direct URLs when possible (faster than clicking through menus)
  • Always sleep 4-6 after navigation — SPAs load content asynchronously
  • If page seems blank, try screenshot first — content may be rendered but not in DOM snapshot

Element Interaction

  • Use snapshot to get element refs, then act with refs
  • For iframe content: use frame parameter in snapshot
  • If compact snapshot misses content, try full snapshot or screenshot
  • GHL and complex SPAs often render in iframes — check both main page and iframe

Screenshots vs Snapshots

  • Snapshot — DOM tree, good for finding clickable refs
  • Screenshot — Visual image, good for understanding what's actually on screen
  • When snapshot shows empty/minimal content but screenshot shows a full page → content is in iframe or shadow DOM

Login Flows

  1. Navigate to login page
  2. Snapshot to find form fields
  3. Click + type credentials
  4. Handle 2FA (check email, enter code)
  5. Wait for redirect (sleep 4-6 seconds)
  6. Verify logged in via screenshot

Common Issues

  • Popups/modals blocking → Press Escape
  • Lazy-loaded content → Wait longer, refresh, or navigate directly via URL
  • iframe content → Use frame parameter or evaluate JS to find iframe
  • evaluate function errors → No const, let, or arrow functions. Use var and function(){} syntax.
  • ref required errors → Must use ref from snapshot, can't use text selectors

SPA-Specific Tips

  • SPAs don't fully reload on navigation — URL changes but DOM updates incrementally
  • Some content only appears after JavaScript execution
  • If clicking a link doesn't work, try navigating directly to the URL
  • F5 refresh can help when SPA state gets stuck
