> Maybe that's the problem that needs solving then? The threshold doesn't have to be "bot capable of doing entire task end to end", like it could also be "bot does 90% of task, the worst and most boring part, human steps in at the end to help with the one bit that is more tricky".

Still, the big short-term danger being you're left with code that seems to work well but has subtle bugs in it, and the long-term danger is that you're left with a codebase you're not familiar with.

Being left with an unfamiliar codebase is always a concern and comes about through regular attrition, particularly if inadequate review is not in place or people are cycling in and out of the org too fast for proper knowledge transfer (so, cultural problems basically).

If anything, I'd bet that agent-written code will get better review than average because the turn around time on fixes is fast and no one will sass you for nit-picking, so it's "worth it" to look closely and ensure it's done just the way you want.
