Github copilot used to only be in line completion. That is not vibe coding.

I wasn't an early adopter of Copilot, but now the VSCode plugin can use Claude models in Agent mode. I've had success with this.

I don't "vibecode" though, if I don't understand what it's doing I don't use it. And of course, like all LLMs, sometimes it goes on a useless tangent and must be reigned in.
