Framework/Thought Process of Diagnosing Prompt Issues

Hey @0xV4L3NT1N3, yeah, this is a very common spot to hit. What you’re describing (wrong tool calls, ignored formatting, extra verbosity) usually comes down to prompt clarity and structure. I’d recommend starting with this official guide on how to create a good prompt. It covers being explicit, separating constraints clearly, and defining output formats, which directly helps with the issues you mentioned. A good rule of thumb: change one variable at a time and test like you’re debugging code. That makes patterns much easier to spot.
