A model can sort, count, and flag. It cannot know your rent, your sleep, or next year's law. Talk to it like a clerk you would check. If it offers a fortune, you have asked the wrong question. Ask it to list, compare, or show its steps.
In money, a fortune sounds like 'this will pay you' or 'buy this now.' Those sentences do not belong in the clerk's outbox. A useful sentence sounds like 'these three months were unusual' or 'this rule would have said stop here.' The past tense matters.
A pretend example. Pretend a tool says a paper rule 'works.' The manners translation is: 'On the dates I was shown, the rule made paper coins, before extra costs.' That sentence is allowed to sit on the desk. The word 'works' is not.
