Bib Verify

agentscope-ai/bib-verify

> Verify a BibTeX file for hallucinated or fabricated references by cross-checking every entry against CrossRef, arXiv, and DBLP. Reports each reference as verified, suspect, or not found, with field-level mismatch details (title, authors, year, DOI). Use when the user wants to check a .bib file for fake citations, validate references in a paper, or audit bibliography entries for accuracy.

BibTeX Verification Skill

Check every entry in a .bib file against real academic databases using the

OpenJudge PaperReviewPipeline in BibTeX-only mode:

  • Parse — extract all entries from the .bib file
  • Lookup — query CrossRef, arXiv, and DBLP for each reference
  • Match — compare title, authors, year, and DOI
  • Report — flag each entry as verified, suspect, or not_found

Prerequisites

pip install py-openjudge litellm

Gather from user before running

| Info | Required? | Notes |

|------|-----------|-------|

| BibTeX file path | Yes | .bib file to verify |

| CrossRef email | No | Improves CrossRef API rate limits |

Quick start

# Verify a standalone .bib file
python -m cookbooks.paper_review --bib_only references.bib

# With CrossRef email for better rate limits
python -m cookbooks.paper_review --bib_only references.bib --email [email protected]

# Save report to a custom path
python -m cookbooks.paper_review --bib_only references.bib \
  --email [email protected] --output bib_report.md

Relevant options

| Flag | Default | Description |

|------|---------|-------------|

| --bib_only | — | Path to .bib file (required for standalone verification) |

| --email | — | CrossRef mailto — improves rate limits, recommended |

| --output | auto | Output .md report path |

| --language | en | Report language: en or zh |

Interpreting results

Each reference entry is assigned one of three statuses:

| Status | Meaning |

|--------|---------|

| verified | Found in CrossRef / arXiv / DBLP with matching fields |

| suspect | Title or authors do not match any real paper — likely hallucinated or mis-cited |

| not_found | No match in any database — treat as fabricated |

Field-level details are shown for suspect entries:

  • title_match — whether the title matches a real paper
  • author_match — whether the author list matches
  • year_match — whether the publication year is correct
  • doi_match — whether the DOI resolves to the right paper

How to use it

Copy the folder

Take agentscope-ai/bib-verify from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference pip. Without those the skill loads but fails at the first command.
