Same command for any agent — swap --agent for codex, cursor, copilot.

# 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. - If exact abstract-page wording, final pagination, or publisher formatting matters, verify the shortlisted record on the publisher or DOI landing page. 7. When title search returns multiple plausible records, keep the ambiguity explicit instead of selecting a mat

What does the crossref-lookup skill do?
Query the Crossref REST API for DOI validation, title search, citation metadata, and bibliography audits. Use when you need DOI lookup, title-to-DOI matching, or reference metadata cleanup.
How do I install it?
Run `npx skills add BioTender-max/awesome-bio-agent-skills --skill crossref-lookup --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From BioTender-max/awesome-bio-agent-skills, a repository with 135 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
