Citation Verifier

Overview

Use this skill when citation integrity is the bottleneck. It is narrower and more operational than general writing skills: the goal is to catch unverifiable references, missing identifiers, duplicated BibTeX keys, placeholder citations, and mismatches between local citation artifacts before they become submission problems.

Use this skill together with scientific-writing or submission-audit, not instead of them.

This is stage one of three. It shows the bibliography is well-formed; it cannot show that the cited papers are real, and it cannot show that a real paper supports the sentence citing it. Hand the surviving entries to reference-audit-guide (optional set, installed with --set all), which queries CrossRef, Semantic Scholar, arXiv, and PubMed to confirm existence and match metadata, then to claim-source-verification for claim-to-evidence support. When reference-audit-guide is not installed, say that existence was not machine-verified rather than letting a clean local scan stand in for it. A fabricated citation carrying a well-formed DOI passes this skill and fails the next one.
