This is sage advice. I spent the better part of a day trying to steer Gemini into correcting an inconsistency when I likely could have solved it in under an hour. I think persevering with Gemini was due to a number of factors, including novelty, stubbornness, and (unfortunately) not knowing in detail what Gemini had written up to that point.

I eventually studied the resulting code, which ended up having a number of nested 'hacks' and required refactoring - more time wasted, but still much faster overall.
