As for sharing a tool that someone else has made that's useful, I don't think most people are advertising that the tools they've built are vibe-coded, so it would be hard to know what to share.
Sometimes that will be in the readme, but there's no reason it has to be. And most people aren't going to be checking anyways.
What definition of "vibe coding" are you using here? I seriously doubt Claude Code was made "mostly" (or even "partly") by telling a prompt what they want, and accepting the output when it looks functionally acceptable without regard to how the code looks or works under the hood.
... Which is what "vibecoding" is.
Vibecoding != AI assisted/agentic coding
