Paper Lookup

Use this skill for external literature discovery and metadata lookup.

Important routing boundary

Do not replace the existing library-first workflow.

Keep this order:

• zotero first for paper/library retrieval
• calibre second for review tasks needing a local document
• paper-lookup for external metadata/discovery
• getscipapers_requester for actual external retrieval when needed

Good use cases

• find papers on a topic
• resolve a DOI, PMID, or arXiv ID
• check whether a paper has an open-access location
• search major literature APIs before retrieval

High-value references

• references/pubmed.md
• references/pmc.md
• references/arxiv.md
• references/biorxiv.md
• references/crossref.md
• references/openalex.md
• references/semantic-scholar.md
• references/unpaywall.md
