Game dev asked Claude to hallucinate a RAG tutorial — the one-shot result mostly held up

A game developer new to LLMs asked Claude for a one-shot, step-by-step RAG tutorial themed around role-playing games, published it as a site, and is implementing it as an open-source project on GitHub.

They found the tutorial surprisingly solid for a single shot, though it grew inconsistent later on — mostly around API endpoints, where the model lost track of earlier setup. The author treats the inconsistencies as learning exercises, vibe-coded the frontend, and asks the community whether this is a viable way to learn RAG and what the blind spots are.
