I have tried and failed to get any LLM to "tell me if you don't have a solution". There may be a way to prompt it, but I've not discovered it. It will always give you a confident answer.

It always has a solution. A more effective approach is "Start by asking clarifying questions until the task is completely defined".

But the questions I'm interested in cannot be asked until the programmer starts to code. It's not that the task is unclear, but that coding reveals important subtleties.
