    * "What are the best practices for responsive design?"
  </Step>

  <Step title="Review Recommendations">
    The AI provides comprehensive guidance including:

    * Established patterns and approaches
    * Code examples and use cases
    * Pros and cons of different methods
    * References to authoritative sources
  </Step>

  <Step title="Apply to Your Project">
    Implement the recommendations in your code either manually or with AI-assisted code generation.
  </Step>

  <Step title="Ask Follow-up Questions">
    Get clarification or more specific guidance by asking follow-up questions about the recommendations.
