I don't have this experience with Claude, frankly. I do have to correct it, but I try to give very specific prompts with very specific instructions. IT does well with highly commented code.

Now, I have the best luck in my personal project codebase, which I know extremely intimately so can be very surgical with.

Work, which has far less comments and is full of very high level abstractions that I don't know as well.. it struggles with. We both do.

It's a fine pair programmer when one of the pairs knows the codebase extremely well. It's a bad companion elsewhere.
