Fair enough. I guess I was mainly thinking of how rarely I need to utilise the old prompt engineering techniques. Stuff like: "You are an expert software developer...", "you must do this or people will die." etc

I just tell the AI what I want, with sufficient context. Then, I check the reasoning trace to check it understood what I wanted. You need to be clear in your prompts, sure, but I don't really see it as "prompt engineering" any more.
