Tool Selection Tips​

  1. Use indices - click_by_index and fill_by_index are more reliable than CSS selectors
  2. Check page content first - Always call get_page_content to see available elements
  3. Use subagents for complex tasks - Break down multi-site comparisons into parallel subagents
  4. Wait after navigation - Pages need time to load after navigate_to_url
