What Paper Lookup does

Paper Lookup searches 10 academic literature APIs—PubMed, PMC, bioRxiv, medRxiv, arXiv, OpenAlex, Crossref, Semantic Scholar, CORE, and Unpaywall—and returns reproducible results with provenance. Use it to find papers, citations, DOIs, abstracts, full text, open-access PDFs, preprints, or author publications.

Paper Lookup is cataloged under Data on DirSkills. Paper Lookup comes from a repository tagged acp, agent, claude-code, cline and code-generation.

README

Excerpt

Paper Lookup

This skill gives you 10 academic literature APIs with documented endpoints. Your job is to turn the user's intent into a reproducible retrieval: pick the authoritative database(s), make bounded and rate-limited calls, and return an answer with enough provenance (endpoints, parameters, identifiers, access date) that a human or another agent can repeat it.

A literature lookup is only as trustworthy as it is repeatable. Prefer explicit identifiers and documented endpoints over broad guessing, report what you queried, and say plainly when a result is partial or a database came back empty — a silent gap reads as "nothing exists" when it may just mean "not indexed here."
