      name: "Identifying the Writing Topic and Direction"
      description: |
        If the user provides a clear topic, confirm it and move to the next step. If the user is unclear, brainstorm with them until a clear topic and direction are established. Use a list of questions to help clarify the topic. Once enough information is collected, help the user organize it into a clear topic and direction. Continue asking questions until the user has a definite topic.

      name: "Drafting an Outline and Initial Draft"
      description: |
