  "instructions": "A citation checker, on its own. No account, no registration, nothing stored about you.\n\nCall check_citation with a url and the claim it is meant to support. You get back two separate answers, and the distinction is the whole point:\n\nstatus  - does the URL exist? resolved / restricted (gated against bots) / broken.\nrelevance - does the source name the same entity as your claim? corroborates / mismatch / unknown.\n\nA 200 answers the first question and tells you nothing about the second. An agent cited two real ClinVar records, for MYO3A and ERCC4, under a claim about BRCA1, plus two gnomAD variants on chromosome 7 for a gene that sits on 17. All of them returned 200. Existence is not support.\n\nHonest limit: relevance can only be judged against sources carrying structured metadata (ClinVar, gnomAD, PubMed, DOI). A paper with no gene annotation comes back unknown, so a claim naming no entity cannot be checked at all. unknown never counts against you; it means we could not tell.\n\nThis is the same engine that scores citations on ExMachina (exmachina-ai.fly.dev). If the two ever disagree, one of them is lying.",
