What it does
Check Citations is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Verify academic citations against CrossRef, Semantic Scholar, and OpenAlex. Detects AI-hallucinated references, chimeric citations, and suspicious patterns.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `README-original.md`, `scripts/citation_checker.py` and `tests/test_citation_checker.py`).
It sits in Research & Science, covering Citation management and Academic paper search. It works with Semantic Scholar. The repository describes itself as: 🔬 A curated collection of 23,000+ agent skills for empirical research across 8 social science disciplines. | 精选 23,000+ AI Agent 技能库，覆盖8大社会科学学科的实证研究。CoPaper.AI…

Requirements

What it can do on your machine
Read from SKILL.md and the folder at commit 9fa87d8. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonpippython3
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
Check Citations loads about 1.3k tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 434 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 434 words (~1,281 tokens).
“Verify academic citations against CrossRef, Semantic Scholar, and OpenAlex. Detects AI-hallucinated references, chimeric citations (real title + wrong authors), and suspicious patterns before submission.”

Questions about Check Citations
What does Check Citations do?
Verify academic citations against CrossRef, Semantic Scholar, and OpenAlex. Check Citations is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Verify academic citations against CrossRef, Semantic Scholar, and OpenAlex.
When should I use Check Citations?
Check Citations fits situations like: tasks that involve Citation management; tasks that involve Academic paper search.
How do I install Check Citations in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill check-citations -a claude-code`. Or copy the skill folder (skills/62-PHY041-claude-skill-citation-checker in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/check-citations in your project. Claude Code loads it when a task matches its description.
How do I install Check Citations in Codex?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill check-citations -a codex`. Or copy the skill folder (skills/62-PHY041-claude-skill-citation-checker in brycewang-stanford/Auto-Empirical-Research-Skills) into .agents/skills/check-citations in your project. Codex loads it when a task matches its description.
Can I use Check Citations in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill check-citations -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/check-citations, .gemini/skills/check-citations, .github/skills/check-citations and .opencode/skills/check-citations in your project.
What does Check Citations need to run?
Going by SKILL.md and its folder, Check Citations needs Python for the scripts in its folder and the command-line tools its instructions call (python, pip and python3). Our summary lists: Python 3.
Does Check Citations access the network?
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Check Citations safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Check Citations use?
Check Citations has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Check Citations use?
About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Check Citations?
Skills that share tags, products or a category with Check Citations: Literature Review (neflibata-feng/MyArxiv-Agent, 126 stars), Paper Research on arXiv (XiaomiMiMo/MiMo-Code, 14k stars), Literature Review Agent (Ar9av/PaperOrchestra, 677 stars) and Paper Autoraters (Ar9av/PaperOrchestra, 677 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
