Group 13 failing shopping-bot traces into 3 failure types

Practice: Asking for a format you can use. About 5 minutes.

About this exercise

You reviewed 13 failing traces from your AI shopping assistant and wrote a quick note on each. Group them into exactly 3 numbered failure categories, each line 'Category name: #ids = count', then one last line 'Total: N'. Leave out any trace that passed on re-check. Plain text, under 70 words.

Common mistakes when you ask AI for this

  • Too many categories. The AI splits the notes into 6 or 7 small groups, so no clear fix stands out. Try: Say: "Exactly 3 categories."
  • No ids or counts. The AI describes the problems in prose but you can't see which traces belong where. Try: Show the shape: "Category name: #1, #3 = 2".
  • Counting the re-checked trace. The AI counts every numbered note, including the one that passed on re-check. Try: Add: "Leave out traces that passed on re-check, and end with Total: N."
  • Repeating the guess. The AI may echo 'retrieval issue' instead of grouping what the traces actually show. Try: Say: "Group only by what the notes say."
  • Getting markdown back. AI defaults to bold category names and headings. Try: Ask for "plain text, no bold, no headings."

What a strong prompt includes

  • Says exactly how many
  • Asks for ids and counts
  • Handles the re-checked trace
  • Asks for a total
  • Asks for plain text
