OPEN LESSON

Open lesson: Frame the task

Before automating a task, define the result you need and the evidence that would make it trustworthy. In this course, the goal is: Complete a useful repository task with a clear plan, verified changes, and a reliable handoff. AI can accelerate a draft, comparison, or exploration, but it does not know your policies, full context, or the cost of being wrong. Begin with a low-risk case and keep the earlier version so you can compare, explain, and reverse the decision.

  1. Define the deliverable and an observable quality criterion: Turn a business need into an actionable Codex request.
  2. Set context, allowed data, and human review before generating: Use repository context, tools, and checkpoints effectively.
  3. Check the output and document the final decision: Review diffs, tests, security risks, and deployment evidence.
