It's a very very bizarre way to use a computer.
Personally, I just don't. I'll use and prompt the LLMs the way that feels natural to me and move on with my life. Maybe I don't always get completely optimal results from them, but im also not spending half my day pleading with the computer to do a task.
I also don't think I need to prompt Claude differently than Codex.

Other than that the results seem similar, at least functionally. I do not usually review the code style.
