Good luck trying to debug the code you've generated without knowing anything about what it does.
Is this really any different from debugging code that has been built by hundreds of people over 10s of years and you're just the latest schmuck working on it?
But regardless, on a large project, you're always going to have some version of this problem. At least when you yourself are getting in there and writing and understand the code, you have a half-decent shot at debugging in a reasonable period of time. When even you are vibe coding your additions to the pile, you're all the way back at square one when shit hits the fan, trying to learn it all from scratch.
