Even as a “Vibe Coder” you kind of still need to know the idea of what code you need and what you want it to do.

I've fiddled with it a bit. IM(limited)E, you tend to get the best results if what you tell it you want broadly, and then in a significant level of detail, and especially if you tell it to ask you any questions it has about the design. So something like "I want you to build an app in $LANGUAGE that does $TASK on $PLATFORM. As I see it, I think the interface should look like $DETAILED_DESCRIPTION_OF_INTERFACE and here's what should happen when those elements are interacted with,,, Please ask as many questions as you think are necessary for clarity."

Also, unless you're setting it to require personal approval for every terminal command, I'd only run one of those in a VM of some kind, where any potential damage from any potential fuckups are limited.
