Quality lives in the constraints you put around your agent. Autonomy is earned by passing verification loops.
I like to think off it as high autonomy, gated autonomy & human as a must.
There's no upside in hating on someone's idea. You come off as non-believer or ruin their confidence. Instead, just ask the questions that make you hesitate & let them come to their own conclusion. If you're right, you helped them think it through. If you're wrong, you'll learn.
