I was using it the same way you just described but for C# and Angular and you're spot on. It feels amazing not having to memorize APIs and just let the AI even do code coverage near to 100%, however at some point I began noticing 2 things:

- When tests didn't work I had to check what was going on and the LLMs do cheat a lot with Volkswagen tests, so that began to make me skeptic even of what is being written by the agents

- When things were broken, spaghetti and awful code tends to be written in an obnoxius way it's beyond repairable and made me wish I had done it from scratch.

Thankfully I just tried using agents for tests and not for the actual code, but it makes me think a lot if "vibe coding" really produces quality work.
