How to use it in Claude

If the first answer is vague, reply with the constraint again: row counts.
Have Claude list assumptions about data analysis before drafting. Delete any you cannot defend. For join debugging in data analysis, the failure mode is usually no example.

- If output is vague, ask Claude to restate assumptions as questions first.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Join Debugging, 3 short sections, bullet list of recommendations, closing line that states row counts. Facts you supply appear; nothing invented.
