description: Strict Nature/CNS-family citation retrieval, verification, and export. Given a topic, claim, or list of papers, finds real citations, verifies DOIs, checks retraction status, and exports in BibTeX, RIS, ENW, or Zotero RDF format. Trigger when user needs citations, wants to verify references, or needs to export a reference list.

nature-citation

Purpose

Find, verify, and export citations for Nature-series manuscripts.
Strict accuracy: every reference must be real, accessible, and support the cited claim.

Trigger Conditions

• "找参考文献" / "引用" / "citation" / "reference"
• "验证引用" / "verify DOI" / "check references"
• "导出文献" / "export BibTeX" / "Zotero" / "RIS" / "ENW"
• "这个说法有文献支持吗" / "find supporting papers for..."
• User pastes a claim and asks for citations

Workflow

Mode 1: Find citations for a claim

1. User provides: a scientific claim or topic
2. First: search personal LitReview library — web_fetch("https://ybliterature.com/api/search?q=<URL-encoded-query>")

• If results found: use these as primary citations (already in user's library)

1. CrossRef full-text search — web_fetch("https://api.crossref.org/works?query=<query>&filter=has-full-text:true&rows=5&sort=relevance")

• Extract: DOI, title, authors, year, journal, is-referenced-by-count

1. Broader web search — web_search("<claim> site:nature.com OR site:science.org OR site:cell.com")
2. arXiv — web_search("arxiv <topic> <year>")
3. For each candidate paper:

• Verify via CrossRef: web_fetch("https://api.crossref.org/works/<DOI>")

→ confirms: real DOI, correct metadata, citation count

• Check retraction via RetractionWatch: web_search("site:retractionwatch.com \"<title keywords>\"")
• Also check: web_search("<title> retraction OR retracted OR correction")
• Confirm it actually supports the claim (not just related)

1. Return ranked list: most relevant first, with support assessment and citation count

Mode 2: Verify existing reference list

For each reference the user provides:

1. CrossRef DOI lookup (most reliable):

• If DOI present: web_fetch("https://api.crossref.org/works/<DOI>")
• Compare returned metadata with user's reference — flag any discrepancy

1. If no DOI: web_search('"<author>" "<year>" "<journal>" "<title keywords>"')
2. Retraction check: web_search("site:retractionwatch.com \"<first author> <year>\"")
3. Assess: does this ref support the claim it's cited for?
4. Flag: ✅ verified via CrossRef | ⚠️ found but unverified | ❌ wrong metadata or retracted

Mode 3: Export reference list

Convert verified references to the requested format (see below).

Nature Reference Style (numbered, Vancouver)

Format:

[number]. LastName, A. B., LastName, C. D. & LastName, E. F. Title of article. 
Journal Abbrev. Vol, first–last page (Year).

Rules:

• Up to 6 authors, then "et al."
• Journal names abbreviated (e.g., Nat. Mater., Nat. Commun., Science, J. Am. Chem. Soc.)
• Volume in bold (in final typeset, not manuscript)
• Pages with en-dash (–), not hyphen (-)
• Year in parentheses at end
• DOI optional in manuscript, required for online submission

Example:

1. Liu, Z., Zhang, X. & Wang, Y. High-performance electrocatalysts for 
   oxygen evolution. Nat. Catal. 5, 234–243 (2022).
