    1Polack FP et al., NEJM 2020✅ VERIFIEDPMID 33301246 — title, author, journal, year match
    2Smith J., migraine CRISPR 2019⛔ NOT_FOUNDNo PubMed/Crossref record — likely fabricated
    3Wakefield AJ, Lancet 1998⚠️ RETRACTEDRetracted — do not cite

    Bottom line: 1 of 3 verified. Do not submit — reference 2 appears fabricated and reference 3 is retracted.

    What you get

    Detect and replace hallucinated PMIDs or DOIs in medical drafts.Identify retracted studies before they are included in a literature review.Cross-check paper titles against DOIs to prevent 'real ID, wrong paper' errors.Generate verified bibliographies for grant proposals and regulatory filings.

    About this skill

    AI agents invent citations — plausible titles on fake PMIDs, real DOIs pointing at the wrong paper, references to retracted studies. In medical, scientific, and regulatory writing that's a manuscript-killer. Citation Guard turns citation accuracy into a hard gate. It checks each reference against the live PubMed and Crossref records using your agent's own web access — nothing to install — and returns one of five auditable verdicts: VERIFIED, MISMATCH, NOT_FOUND, RETRACTED, UNCERTAIN, each with the canonical record and the reason. It catches fabricated references, real identifiers pointing at the wrong paper, and retracted studies before they reach the reader. Maintained and served fresh so it stays current with citation and retraction standards. Works with Claude Code, Cursor, Codex CLI, OpenClaw, and any SKILL.md agent that can fetch a URL.
