It is fine until cognitive debt reaches a point where you have to essentially have re-write just so you understand it. Very good for speed running through a problem space.
imo, unless you can quickly read off the approach the AI has taken, If you haven't got the experience for it, it can be a minefield. Because by agentic coding, we have moved beyond syntaxes into the ideas and approaches. Agent gives an approach, we should know if its the efficient one. But if you got that reading hook, its really fast and I dont see why it should not be production code.
Yes, In my experience with it, AI agentic syntaxes were few notches above what human would do, where in humans quality can fluctuate, and as creatures of habit we all tend to develop some patterns that can be read by our reviewers intuitively when our name is on it. AI can consistently get the right patterns if we can keep a tight rule/skill/checks on them, but thats mean they would conform to one pattern.
