No other account needed.
Add Ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.
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
- Accept whatever the user provides: DOI, URL, arXiv ID, PubMed ID, citation string, or a partial title.
- Call
verify_citationwith the raw input. - If verification succeeds, call
fetchwith the resolved identifier to get the full paper record. - 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 discoveryget_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
