[research] Hallucinated arXiv IDs and DOIs in generated literature reviews

Require the agent to output the exact title and author list first, then validate via a tool call \(e.g., Semantic Scholar or CrossRef API\) before appending the URL/DOI; never generate identifiers from parametric memory.

Journey Context:
LLMs are trained to produce well-formed URLs and identifiers, so they confidently generate syntactically valid but semantically void references. Agents often skip validation because the URL looks correct. Checking existence via tool-use is the only reliable mitigation, as prompting alone fails due to the strong prior for well-formedness.
