After four long months of side-hustle, dozens of "chats", and hundreds of AI-assisted iterative prompt refinement passes, I have successfully created an AI agent which will ingest technical product documentation and become a product-oracle, giving detailed answers and correcting/clarifying unclear or incorrect assumptions in the questions. It it accurate. It is thorough. It is the first truly useful thing I have gotten out of LLM AI technology. It is a work of art.
And one time out of 7, it STILL makes up its answer whole-cloth!
