Agent eval set starter

Run these in order against your own tickets. The output is an eval set, which is the thing that tells you whether a prompt change helped or just moved the failure.

  1. 1 · Mine real cases from the inbox

    You have an export of past tickets and need the twenty that matter.

    Here are [N] support messages from our inbox.
    
    [PASTE TICKETS]
    
    Group them by the underlying request, not by wording.

Flag any group where the messages disagree about what the customer wanted — those are the ones worth looking at twice.
  2. 2 · Turn one ticket into an eval case

    For each group from step 1.
