paper-reference-checker
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.

Systematically verify academic references to detect AI-hallucinated or fabricated citations. Queries Google Scholar, arXiv, CNKI, and other databases.
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)
- DOI → https://doi.org/{DOI} — resolves = ✅ confirmed
- arXiv ID → https://arxiv.org/abs/{ID} — match = ✅ confirmed
- Google Scholar → search "Full Title"
- arXiv search → arxiv.org/search/
- CNKI → cnki.net
- 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
See examples/sample-report.md for full example.
