Surely there's some point at which you can take over, and they'll have saved you time while not causing too much agony?

Maybe it’s a personal thing but I found that at some size it would be like having someone chuck a big foreign codebase in your lap and saying, “Ok, I did most of it, now you make it work.”

I kinda have to stay engaged the whole time the best I can.

What that boils down to is, “go ahead and yolo small things I can fully review” or “really wrangle it close through a larger effort” or “go full vibecode and prayer.”
