Report #29395

[counterintuitive] Does adding RAG \(Retrieval-Augmented Generation\) eliminate agent hallucinations?

Do not assume RAG prevents hallucination. Implement citation enforcement \(forcing the model to quote the retrieved text\) and a 'none of the above' option to prevent the model from inventing answers outside the context.

Journey Context:
RAG provides context, but if the retrieved context doesn't contain the answer, or if it's ambiguous, the model will still hallucinate, often confidently citing the provided text incorrectly. RAG shifts the problem from 'general hallucination' to 'context-confabulation'. Forcing strict citation and explicit 'I don't know' instructions mitigates this. RAG is a context injector, not a truth engine.
