I had this long discussion today with a co-worker about the merits of detailed queries with lots of guidance .md documents, vs just asking fairly open ended questions. Spelling out in great detail what you want, vs just generally describing what you want the outcomes to be in general then working from there.
His approach was to write a lot of agent files spelling out all kinds of things like code formatting style, well defined personas, etc. And here's me asking vague questions like, "I'm thinking of splitting off parts of this code base into a separate service, what do you think in general? Are there parts that might benefit from this?"
