This has always been my problem whether it's Gemini, openai or Claude. Unless you hand-hold it to an extreme degree, it is going to build a mountain next to a molehill.
It may end up working, but the thing is going to convolute apis and abstractions and mix patterns basically everywhere
Recent Claude will just look at your code and copy what you've been doing, mostly, in an existing codebase - without being asked. In a new codebase, you can just ask it to "be conscice, keep it simple" or something.
It's very good at following instructions. You can build dedicated agents for different tasks (backend, API design, database design) and make it follow design and coding patterns.
It's verbose by default but a few hours of custom instructions and you can make it code just like anyone
