Give instructions, get good code back. That's the dream, though I think the pieces that need to fall into place for particular cases will prevent reaching that top quality bar in the general case.
I can't wait for the first AI agent programmer to realize this and start turning down jobs working for garbage people...or exploiting them at scale for pennies each, in a labor version of the "salami slicing" scheme. I don't mean humans using AI to do this, which of course has been at scale for years. I mean the first agent to discover a job prioritization heuristic on its own which leads to the same result.
