> Humans have strategies for refactoring, e.g. "I'm going to start from the top of the file and Cut code that needs to be moved and Paste it in the new location". LLM don't have a clipboard (yet!) so they can't do this.

For my own agent I have a `move_file` and `copy_file` tool with two args each, that at least GPT-OSS seems to be able to use whenever it suits, like for moving stuff around. I've seen it use it as part of refactoring as well, moving a file to one location, copying that to another, the trim both of them but different trims, seems to have worked OK.

If the agent has access to `exec_shell` or similar, I'm sure you could add `Use mv and cp if you need to move or copy files` to the system prompt to get it to use that instead, probably would work in Claude Code as well.
