Citation Verifier

SkillDev tools

Verify, normalize, and enrich a single citation or paper identifier. Use when the user pastes a DOI, URL, arXiv ID, PubMed ID, citation string, or paper title and wants it checked.

What this skill tells your AI

The instructions your AI receives, as published by hashgraph-online/awesome-codex-plugins in plugins/papersflow-ai/papersflow-codex-plugin/skills/citation-verifier/SKILL.md and read by Ahel’s review.

Use this skill when the user wants to quickly verify or normalize a single paper reference rather than run a full literature search.

Workflow

  1. Accept whatever the user provides: DOI, URL, arXiv ID, PubMed ID, citation string, or a partial title.
  2. Call verify_citation with the raw input.
  3. If verification succeeds, call fetch with the resolved identifier to get the full paper record.
  4. Present the normalized result.

Output Style

Return a clean, structured card with:

  • Title — full paper title
  • Authors — first three authors, et al. if more
  • Year — publication year
  • Venue — journal or conference
  • DOI — canonical DOI if available
  • Identifiers — any additional IDs (arXiv, PubMed, Semantic Scholar)
  • Status — whether the citation was verified successfully or had issues

If verification fails or is ambiguous, say so clearly and suggest what the user can try (e.g., a more complete title, a different identifier).

Tool Guidance

Use verify_citation

Always call this first. It handles:

  • DOI strings (with or without resolver prefix)
  • arXiv IDs (e.g., 2301.12345, arXiv:2301.12345)
  • PubMed IDs
  • full or partial URLs from publisher sites, Semantic Scholar, Google Scholar
  • free-text citation strings (e.g., "Smith et al. 2020, Neural networks for...")

Use fetch

Call after successful verification to hydrate the full paper record with abstract, citation count, and venue details.

Do NOT use

  • search_literature — this skill is for a known reference, not topic discovery
  • get_citation_graph — the user wants verification, not graph exploration

Examples

  • User pastes: 10.1038/s41586-021-03819-2
  • User pastes: https://arxiv.org/abs/2301.12345
  • User says: "Check this cite: Vaswani et al., Attention Is All You Need, NeurIPS 2017"
  • User says: "Is this DOI valid? 10.1234/fake.doi.000"
  • User pastes a Semantic Scholar or Google Scholar URL
