Crossref Lookup

Use this skill for citation metadata work backed by the Crossref REST API.

Instructions

  1. Prefer this skill when the user needs DOI validation, title search, citation metadata, or bibliography auditing.
  2. Use the bundled CLI:
    • In this repository: skills/crossref-lookup/scripts/lookup
    • After installation: ~/.agents/skills/crossref-lookup/scripts/lookup
  3. Choose the narrowest mode that matches the request:
    • --doi for validating or enriching one DOI
    • --title for title-to-DOI discovery
    • --validate-file for one DOI per line
    • --audit-bibliography for a bibliography file such as .bib or plain text
  4. Normalize DOI strings before interpreting failures.
    • Acceptable raw forms include 10.xxxx/..., doi:10.xxxx/..., and https://doi.org/10.xxxx/...
  5. If the user has a contact email for polite-pool requests, pass it with --email.
  6. Treat Crossref as citation metadata, not full text.
