Citation Verifier

Detect and verify citations in scientific documents to identify hallucinated, broken, or invalid references.

Purpose

AI-generated content sometimes includes plausible-looking but fake citations. This skill systematically extracts all citation identifiers from a document and verifies each one against authoritative sources, producing a detailed report with verification status and suggestions for fixing invalid citations.

When to Use

This skill should be invoked when:

• User asks to "verify citations" or "check references" in a document
• User suspects hallucinated citations in AI-generated content
• User wants to validate DOIs, URLs, or other identifiers in a paper
• User asks to audit a document for broken links or fake references
