name: academic-literature-search description: "Query design across arXiv / Semantic Scholar / OpenAlex / CrossRef / PubMed / Unpaywall via the unified academic_search tool."

Academic literature search

• Use academic_search — it fans out across arXiv, Semantic Scholar, OpenAlex, CrossRef, and (when relevant) PubMed, then dedupes by DOI and reciprocal-rank-merges.
• Google Scholar has no public API. Do not pretend to call it; the unified search covers essentially the same corpus.
• Iterate the query: start broad, then add field-of-study, year, or author filters; widen if 0 hits.
• For a known paper, prefer academic_get_paper with a DOI / arXiv id / S2 id over re-searching.
• For citation graph hops, use academic_get_citations and academic_get_references.
• To read the actual paper: academic_find_pdf (Unpaywall + arXiv fallback). If no OA copy exists, say so and offer the abstract/citation.
