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
