What it does

02 Bib Verify is an agent skill from agentscope-ai/OpenJudge. 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.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Citation management and Academic paper search. It works with LaTeX and arXiv. The repository describes itself as: OpenJudge: A Unified Framework for Holistic Evaluation and Quality Rewards. The licence is Apache-2.0.

When your agent uses it

  • The user wants to check a .bib file for fake citations
  • Validate references in a paper
  • Audit bibliography entries for accuracy

Example prompts

  • “/02-bib-verify”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit d1e0642. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

02 Bib Verify loads about 681 tokens when it runs. Until then it costs about 101 tokens; SKILL.md has 213 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~101
When it runs · the whole SKILL.md, loaded when a task matches
~681

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

BibTeX Verification Skill

Check every entry in a .bib file against real academic databases using the OpenJudge PaperReviewPipeline in BibTeX-only mode:

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

Prerequisites

bash
pip install py-openjudge litellm

Gather from user before running

Quick start

bash
# 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 your@email.com

Interpreting results

Each reference entry is assigned one of three statuses:

StatusMeaning
verifiedFound in CrossRef / arXiv / DBLP with matching fields
suspectTitle or authors do not match any real paper — likely hallucinated or mis-cited
not_foundNo 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
