A non-technical employee of a client vibe-coded an app and I was asked to review and deploy it.

It was okay, not bad at all. No serious issues.

At the same time, me feeding a whole PDF of feedback from a client - screenshots and such - into Claude, and it fixed everything after 7 hours of reproducing and fixing things mostly unattended, creating a bunch of MRs with fixes. Most fixes were good, some were obviously not what the client wanted but technically correct (which I told Claude and it fixed it)
