ref-verify — Reference Hallucination Guard

The specific failure this skill prevents: LLMs describe paper content from recalled training data rather than from what the abstract actually says. A paper gets attributed findings it doesn't contain, or cited for claims that appear nowhere in the text. The fix is one rule applied consistently:

Every content statement about a paper must come from a live-fetched source — abstract for topline/headline claims, full text for mechanism/implementation/procedural claims — quoted or paraphrased verbatim. If you cannot fetch the required source, say so explicitly — never fill the gap with recalled description, and never let a topical abstract match stand in for a mechanism-level claim.

Mode Decision

Pick the mode before doing any work. The choice controls cost and depth.

User provides DOI(s) for sanity check?
  └─ ≤10 refs → Quick Screen all
  └─ >10 refs → Quick Screen all; Full Audit only MISMATCH/DEAD results

User says "find papers on X" or "cite papers supporting claim Y"?
  └─ Full Audit (searching from scratch requires content verification)
