I won't be using #claudecode for package renaming anytime soon. It took ten times longer than using #IntelliJ 's built-in refactoring tools.

GenAI will say: sure, here’s X.
The job of the dev has never been to write the code for X.
The job of the dev has always been to say "what do you really want and how can I give it to you within the constraints of the existing system, org and team"
