It's an impossible goal. "Perfection" is subjective and situational. It's basically impossible to specify a non-trivial task perfectly, and without a perfect specification you can't have a consistently perfect result.

Personally I find it much more efficient to give vague instructions and refine on the way, rather than trying to specify everything up front. With this workflow there is no such thing as a one-shot, I don't even know all the details of my intended result until I reach it.

Sure it can one-shot many small things, but for a larger feature it has to be a incremental process. Even when I have a Figma design to work from it never contains all the details like semantics of how various interactive elements work, edge cases etc.
