--- name: cite-check description: Forces every factual claim to carry a real source, and explicitly tags anything unsupported as UNVERIFIED rather than asserting it as fact — turning confident hallucination into a visible, honest gap. Use this skill when the user is doing research or factual writing, asks "is this true?" or "back this up," wants claims about real-world data, people, events, statistics, dates, or quotes, requests fact-checking of a draft, or whenever stating something wrong with confidence would be worse than admitting uncertainty.
