1. Separate facts from suggestions
An answer can mix supplied facts, guesses and recommendations. Ask it to identify those categories. Verify important claims using the original documents or authoritative sources.
2. Check numbers independently
Recalculate totals, percentages and units. Check the period and currency. A confident explanation is not evidence that the calculation is right.
3. Open the sources
Check that a source exists, supports the claim and applies to your situation. A citation alone does not prove the answer. Confirm dates when the information could have changed.
4. Make uncertainty visible
If the input is incomplete, keep the gap visible. Replace an invented answer with a question, a placeholder or an explicit assumption for review.
Review this answer. Separate supplied facts, assumptions and suggestions. List the claims I need to verify, and explain what evidence would verify each one.
