To answer your question from a practical perspective, you can try to run it, and feed back errors. See: https://news.ycombinator.com/item?id=35446171

But that's actually not what I meant. You can often just tell it "there's a problem, please fix it", or "do you see any problems" and it will be able to identify it without additional input. There no requirement that you've identified a problem, it's more of a "double check that" type of prompt.
