I was handed a project someone vibe coded with Claude and it took me hours just to get it running to discover it was missing the entire interface and all the queries were for sqlite while the DB to setup for it was mysql. The patch diff file between what claude produced and the functional version I got working was over 11k lines

I'm the OP and this is the exact point of the post. Whoever handed you that project did not have Claude code running it end to end in a production-like environment.

Whether you like the vibe coded app or not, you would have had fewer errors if Claude had been testing it end to end while vibe coding.
