[research] Generating plausible but non-existent academic citations, DOIs, or URLs

Implement strict citation verification: extract claimed citations, query an external database \(e.g., Semantic Scholar API, Crossref\), and only return citations that return exact matches. If no verification is possible, explicitly state 'Citation unverified' or omit the citation entirely.

Journey Context:
LLMs are trained to predict plausible token sequences, making them excellent at generating realistic-sounding paper titles and author lists that do not exist. Relying on the LLM's internal memory for citations guarantees a high hallucination rate. Agents often assume that if a URL or DOI format looks valid, the resource exists. Verification against a ground-truth index is the only reliable mitigation.
