In my experience, this is a tedious part of programming which I do not spend very much time on.

In my experience LLM generated API boilerplate is acceptable, yet still sloppier than anything I would write by hand.

In my experience LLMs are quite bad at generating essentially every other type of code, especially if you are not generating JS/TS or HTML/CSS.
