Report #44584

[research] Agent generates markdown documentation with fabricated URLs or DOIs

Never generate a URL, DOI, or RFC number from memory. Only output links that are verbatim present in the input context. If citing an RFC, verify the number against an official index or explicitly state 'RFC \[Number\] \(unverified\)'.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating structurally valid URLs \(e.g., https://arxiv.org/abs/2310.xxxxx\) that are entirely fake. This is the fabricated-citation failure mode. The only reliable mitigation is strict grounding: if the URL isn't in the prompt/retrieved context, it doesn't go in the output.
