Yeah it's really funny to watch. They'll get stuck in a specific method call or a specific import. Even if you tell them to read the docs. Doesn't matter if there's a better approach, or that method only exists for some obscure edge case, or the implementation runs counter to the design of the API, if the can hammer the round peg into the square hole, they'll do it.
They also just... Ignore shit. I have explicit rules in the repo I'm using an agent for right now, that day it is for planning and research only, that unless asked specifically it should not generate any code. It still tries to generate code 2 or 3 times a session.
