I just run into this issue with claude sonet 4.5, asked it to copy/paste some constants from one file to another, a bigger chunk of code, it instead "extracted" pieces and named them so. As a last resort, after going back and forth it agreed to do a file/copy by running a system command. I was surprised that of all the programming tasks, a copy/paste felt challenging for the agent.

I guess the LLMs are trained to know what finished code looks like. They don't really know the operations a human would use to get there.
