With Claude code, or codex, I am able to build enough of an understanding of dependencies like the front end, or data jobs, that I can make meaningful contributions that are worth a review from another human (code review). You have up obviously explore the code, one prompt isn’t enough, but limiting yourself is an odd choice.
As for Claude - as mentioned I do use it. But, I remember they use your code for training their models. I am not ok with this. We just have different priorities.
