Fixing bugs is also changing project code to make tests pass. The assistant is pretty good at knowing which side to change when it’s working from documentation that describes the correct behavior.
It's entirely possible to have specifications somewhere between "vague hand-wavy descriptions" and source code. But it's really not my job to defend AI against all the people who want it to be completely useless, seem to need it to be so, really. I just use it, it works a lot of the time, doesn't work other times, and that's that. Results carry more weight than opinions.
It's not a problem. It's in fact the core trait of vibe-codig. The primary work a developer does in vibe coding tasks is providing the necessary and sufficient context. Hence the inception of the term "context engineering". A vibe coder basically lays out requirements and constraints that drives LLMs to write code. That's the bulk of their task: they shift away from writing the low-level "how" to instead write down the high-level "what".

No. The prompts are as elaborate as you want it to be. I, for example, use prompt files with the project's ubiquitous language and requirements, not to mention test suites used for acceptance tests. You can half-ass your code as much as you can half-ass your prompts.
