paper reference checker

---

name: paper-reference-checker description: This skill should be used when the user asks to "check paper citations", "verify references", "detect fake citations", "validate bibliography", "check if papers exist", "查文献真伪", "检查论文引用", "验证参考文献", "识别虚假引用", or uploads a PDF/Overleaf document and wants to verify whether the cited papers genuinely exist. Provides systematic verification of academic references against Google Scholar, CNKI, arXiv, and other academic databases to detect AI-hallucinated or fabricated citations. version: 1.2.1

Core Workflow

Phase 1: Citation Extraction (Token-Efficient First)

ALWAYS use targeted extraction before full-document reading — saves 80–95% tokens.

| Input Type | Primary Method | Fallback | |------------|---------------|----------| | arXiv link | arxiv.org/html/{ID} → find references section | Full HTML, then PDF | | PDF file | Last 15–20% of pages only | Expand to 30% → 50% → full | | Overleaf link | Regex cite-keys from .tex → filter .bib/.bbl | Inline bibitem in .tex | | Pasted list | Parse directly | — |

Phase 2: Multi-Platform Querying (Priority Order)

1. DOI → https://doi.org/{DOI} — resolves = ✅ confirmed 2. arXiv ID → https://arxiv.org/abs/{ID} — match = ✅ confirmed 3. Google Scholar → search "Full Title" 4. arXiv search → arxiv.org/search/ 5. CNKI → cnki.net 6. Fallbacks: Semantic Scholar · PubMed · IEEE Xplore · ACM DL · DBLP

Phase 3: Authenticity Judgment

| Status | Label | Criteria | |--------|-------|----------| | ✅ | VERIFIED | Found in ≥1 authoritative DB | | ⚠️ | UNCERTAIN | Partial match | | ❌ | NOT FOUND | No match across all queried channels | | 🔴 | FABRICATED | Non-existent venue, unresolvable DOI | | 🔗 | BROKEN CITATION | [?] marker in PDF body |

Phase 4: Report Output
