You’re collaborating in multiple ways more than you anticipated. What would you do if they brought in another dev to work on it independently?

If you see failure in the projects future due to this, make sure you establish your limits and boundaries and obligations clearly in writing. Don’t get officially saddled with their slop.

If another capable dev was brought in to work on it independently, I think I would help to transfer it to them, and quit afterwards. When the dev would not be capable, I would advise against it. But in this case, it is the decision of the company owners, and they turned out to not be susceptible to any arguments against their decision. They also see themselves as "developers" right now, with the help of the tools they use. Focussing on limits and boundaries in writing is a good point, I will review this where needed if I continue.

Second this.

OP - When it fails (and it will), they will blame you for the failure, not the vibe coded slop. Start looking for a new gig. They're going to fire you eventually anyway.
