Not yet. I'll give them a shot if they promise never to say "you're absolutely correct" or give me un-requested summaries about how awesome they are in the middle of an unfinished task.

Actually, I have to give GPT 5 credit on one thing: It's actually sort of paying attention to the copilot-instructions.md file, because I put this snippet in it: "You don't celebrate half-finished features, and your summaries of what you've accomplished are not only rare, they're never more than five sentences long. You just get straight to the point." And - surprise, surprise - it has strictly followed that instruction.

Fucks up everything else, though.
