Citation Verification Guide
Galaxy-Dawn/claude-scholar
Reference guidance for checking every citation in academic writing against canonical sources such as DOI, arXiv, CrossRef and Semantic Scholar, to catch fake or wrong references.
Cross-checks each academic reference against several sources field by field, flags conflicts such as year, DOI, author order and page errors, and outputs a structured report.

At a glance
Cross-checks each academic reference against several sources field by field, flags conflicts such as year, DOI, author order and page errors, and outputs a structured report.
- Works in 5 steps: 解析输入 → 多源并行查询 → 字段级对比 → …
- Running a final reference check before submitting a paper or proposal
- SKILL.md covers 触发词, 适用场景, 工作流 and 多来源交叉验证策略, plus 2 more sections
- Reaches api.crossref.org
What it does
The skill accepts a whole paper or proposal reference list, a single pasted citation or Zotero item key, or a BibTeX file. Its cheapest first check queries Crossref for every reference that has a DOI: a 404 means the DOI itself is wrong, and a 200 is compared against the title, authors, volume and pages to catch DOIs that point at a different paper. Each reference is then looked up in parallel in Crossref, IEEE Xplore, web search, CNKI or Wanfang for Chinese literature, and a local Zotero library, using the DOI first and title plus author as the fallback.
Findings are graded in three levels. Critical covers wrong or reordered authors, missing authors, large page differences, confused article-number characters, mismatched core title words and DOIs that resolve to other papers. Warning covers a volume year that differs from the DOI year, metadata that changed after Early Access, missing issue numbers, small page drift and publisher name variants, and the third level is informational. Lists longer than 20 are split into groups of 10-15 for parallel subagents.
It suits a final check before submitting a paper or proposal, tracing citation errors a reviewer pointed out, migrating old reference lists and routine Zotero health checks. A common-patterns reference is read only for batch differences, recurring field errors and report wording. The skill text is written in Chinese.
When your agent uses it
- Running a final reference check before submitting a paper or proposal
- Locating citation errors that a reviewer flagged
- Validating a BibTeX file migrated from an older project
- Health-checking a Zotero library
Example prompts
- “Verify the references in this BibTeX file and flag any DOI that points to a different paper.”
- “Check this citation against Crossref and tell me which fields disagree.”
- “Run a reference check on my proposal's list and give me a critical, warning and info report.”
Requirements
- Network access to Crossref and other bibliographic sources
- Zotero MCP access, optionally
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e605b35. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.crossref.org
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
Reference Verifier loads about 1.4k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 394 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); files beside SKILL.md are not scanned.

- 对学术文献逐条执行多源交叉验证，逐字段对比作者、标题、年份、卷期、页码， 标记卷年/DOI年冲突、作者顺序异常、页码偏差等问题，输出结构化验证报告。 可批量处理整篇论文/开题报告的参考文献列表，也可单条校验，支持与 Zotero 同步修正。

报告措辞时，读取 references/common-patterns.md。其他任务不要预加载该文件；
manifest.yaml 记录了同一按需路由，新增资源时必须同时在本文件中写明加载条件。
触发词
verify references、校验文献、check references、核对参考文献、文献验证、ref check
适用场景
- 开题报告/论文提交前，对全部参考文献做最终核查
- 收到审稿意见指出引用错误时，精准定位问题
- 从旧项目迁移参考文献到新论文时，批量验证有效性
- Zotero 库定期健康检查
工作流
Step 1: 解析输入
支持三种输入格式：
A. 整篇论文/开题报告
- 提取所有
[N]编号的参考文献列表 - 自动识别每条的 DOI（如有）
B. 单条参考文献
- 用户直接粘贴一条引用文本
- 或传入 Zotero item key
C. BibTeX 文件
- 直接解析
.bib，逐条校验
Step 2: 多源并行查询
Step 2.0（最便宜、最先做）：DOI 可解析性检查。 对每条有 DOI 的文献先请求 https://api.crossref.org/works/<DOI>：404 → DOI 本身错误（高度疑似错号）；200 → 比对返回记录的标题/作者/卷期页与条目，不一致即"DOI 张冠李戴"。单次请求即可发现实践中最常见的一类错误（一次 35 条核查中 7/9 的错误属于此类）。
对每条文献，并行查询以下来源（可用哪些取决于环境配置）：
| 来源 | 适用文献 | 典型覆盖率 |
|---|---|---|
| Crossref | 有 DOI 的外文期刊 | ~70%（IEEE 老文献、中文期刊常有缺失） |
| IEEE Xplore | IEEE 期刊/会议 | IEEE DOI 404 时的备选 |
| WebSearch (Bing/Google) | 无 DOI 或来源缺失的文献 | 兜底方案 |
| CNKI/万方 (kimi-datasource / webbridge) | 中文期刊、学位论文 | 中文文献必查 |
| Zotero 本地库 (zotero-mcp) | 已入库文献 | 快速比对已有数据 |
查询策略： 优先用 DOI 查 Crossref，失败后降级用标题+作者搜 Web。
批量策略： 超过 20 条时按 10–15 条一组拆给并行子代理，每组独立查询后汇总——35 条规模实测 3 个并行子代理即可在一次往返内完成，串行会慢一个数量级。
Step 3: 字段级对比
对每条文献执行以下对比矩阵，按严重程度分为三级：

Questions about Reference Verifier
What does Reference Verifier do?
Cross-checks each academic reference against several sources field by field, flags conflicts such as year, DOI, author order and page errors, and outputs a structured report. The skill accepts a whole paper or proposal reference list, a single pasted citation or Zotero item key, or a BibTeX file. Its cheapest first check queries Crossref for every reference that has a DOI: a 404 means the DOI itself is wrong, and a 200 is compared against the title, authors, volume and pages to catch DOIs that point at a different paper.
When should I use Reference Verifier?
Reference Verifier fits situations like: running a final reference check before submitting a paper or proposal; locating citation errors that a reviewer flagged; validating a BibTeX file migrated from an older project; health-checking a Zotero library.
How do I install Reference Verifier in Claude Code?
Run `npx skills add Yuan1z0825/nature-skills --skill nature-ref-verifier -a claude-code`. Or copy the skill folder (skills/nature-ref-verifier in Yuan1z0825/nature-skills) into .claude/skills/nature-ref-verifier in your project. Claude Code loads it when a task matches its description.
How do I install Reference Verifier in Codex?
Run `npx skills add Yuan1z0825/nature-skills --skill nature-ref-verifier -a codex`. Or copy the skill folder (skills/nature-ref-verifier in Yuan1z0825/nature-skills) into .agents/skills/nature-ref-verifier in your project. Codex loads it when a task matches its description.
Can I use Reference Verifier 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 Yuan1z0825/nature-skills --skill nature-ref-verifier -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/nature-ref-verifier, .gemini/skills/nature-ref-verifier, .github/skills/nature-ref-verifier and .opencode/skills/nature-ref-verifier in your project.
What does Reference Verifier need to run?
SKILL.md names no scripts, command-line tools or credentials: Reference Verifier is instructions for the agent only. Our summary lists: Network access to Crossref and other bibliographic sources; Zotero MCP access, optionally.
Does Reference Verifier access the network?
SKILL.md names 1 domain. In commands or code: api.crossref.org; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Is Reference Verifier 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. Review the folder before installing.
What licence does Reference Verifier use?
Reference Verifier is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Reference Verifier use?
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 906 tokens, read only when the agent opens those files.
