If you're automating code generation but not automating verification, there will be a mismatch.

Maybe the fatigue comes from that mismatch?

The classical vibe coder style is to just ignore verification. That's not a good approach as well.

I think this space has not matured yet. We have old tools (test, lint) and some unreliable tools (agent assisted reviews), but nothing to match the speed of generation yet.

I do it by creating ad-hoc deterministic verifiers. Sometimes they'll last just a couple of PRs. It's cheap to do them now. But also, there must be a better way.
