So just iterate on it? Your complaint is that the model isn't one shotting the problem and reading your mind about style. It's like any coding workflow, make it work, then make it nice.

No, I never expect AI to one-shot (if I see such a miracle, it's usually because I needed a one-liner or something really simple and well documented, which I can also write on the whiteboard from memory).

Try iterating over well known APIs where the response payloads are already gigantic JSONs, there are multiple ways to get certain data and they are all inconsistent and Claude spits out function after function, laying waste to your codebase. I found no amount of style guideline documents to resolve this issue.

I'd rather read the documentation myself and write the code by hand rather than reviewing for the umpteenth time when Claude splits these new functions between e.g. __init__.py and main.py and god knows where, mixing business logic with plumbing and transport layers as an art form. God it was atrocious during the first few months of FastMCP.
