Report #54451

[research] LLM generates plausible but non-existent academic citations or DOIs

Never trust generated DOIs or URLs; enforce strict citation grounding by requiring the agent to verify the URL resolves or extract strictly from a provided retrieval tool output without modification.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating syntactically valid but factually void citations \(e.g., real author \+ real title \+ fake DOI\). Relying on the LLM to 'recall' a source invariably leads to hallucination. The only reliable mitigation is architectural: the agent must only cite what it can read from tool output, and any structural identifiers \(URLs/DOIs\) must be directly extracted, never synthesized.
