  9. Use templates for quick start:

    • templates/basic-automation.md - Basic automation workflow
    • templates/ai-agent-workflow.md - AI agent workflow template

Doc mapping (one-to-one with official documentation)

Examples and Templates

This skill includes detailed examples organized to match the official documentation structure. All examples are in the examples/ directory (see mapping above).

To use examples:

  • Identify the topic from the user's request
  • Load the appropriate example file from the mapping above
  • Follow the instructions, syntax, and best practices in that file
  • Adapt the code examples to your specific use case

To use templates:

  • Reference templates in templates/ directory for common scaffolding
  • Adapt templates to your specific needs and coding style

API Reference

  • Commands API: api/commands.md - Complete command reference with syntax and examples
  • Selectors API: api/selectors.md - Selector types and usage reference
  • Options API: api/options.md - All options reference

Best Practices

  1. Use Refs: Prefer refs (@e1, @e2) over traditional selectors for deterministic automation
  2. Snapshot First: Always snapshot before interacting with elements to get refs
  3. Agent Mode: Use --json flag for machine-readable output in agent mode
  4. Session Management: Use --session to maintain state across commands
  5. Interactive Snapshot: Use -i flag for interactive snapshot selection
  6. Semantic Locators: Use semantic locators (role/name) when refs are not available
  7. Error Handling: Check command exit codes and error messages
  8. Wait for Navigation: Commands automatically wait for navigation to complete
  9. Headed Mode: Use --headed for debugging, headless for production
  10. CDP Integration: Use --cdp for Chrome DevTools Protocol integration
  11. Streaming: Use AGENT_BROWSER_STREAM_PORT for live browser preview
  12. Authenticated Sessions: Use --headers for authentication without login flows
  13. Custom Executable: Use --executable-path for serverless deployments or custom browsers
  14. Snapshot Options: Combine -i, -c, -d, -s options to optimize snapshot output
