I'd be more general and say it needs verification to guide it, and narrowed scope so it doesn't wander off. How those get provided can vary. While I can do what I'm asking it to do, and have so many times that I don't want to anymore, I can't do it as fast as it can. But as someone said, it is stupid really fast. The bottleneck is now me slowing down this intern who thinks fast by stopping it to redirect it when it does bad things. The more pre prompting and context and verification tools I give it the less I have to do that, so the faster it goes. Then I get to solve the parts of the problem I haven't done until its boring.
