Homework

Three concrete next steps before you run the next session.

  • 1Interview 10 engineering leads at mid-size companies to identify their top 3 pain points with current documentation tools like Swagger or ReadMe
  • 2Build a prototype that connects to one language (e.g., Python or JavaScript) and generates basic endpoint documentation from a sample repo
  • 3Identify 5 developer communities or Slack groups where API documentation pain is frequently discussed and engage authentically to build early interest
