What it does
Paper Search is an agent skill from dr-dumpling/paper-search-cli. 学术文献检索与论文获取调度器，基于 paper-search CLI，而不是 MCP server。 用于：搜索论文、查找相似研究、做文献综述初筛、验证 PMID/DOI、下载论文 PDF、 调用 Crossref/OpenAlex/PubMed/PMC/Europe PMC/arXiv/bioRxiv/medRxiv/Semantic Scholar/CORE/OpenAIRE/DBLP/ACM/USENIX/OpenReview/IACR 等来源， 使用 Semantic Scholar Open Access snippet 索引检索论文正文片段中的方法学细节， 通过 Semantic Scholar Graph API 查询已知论文的施引文献和参考文献， 以及通过 EasyScholar 查询期刊影响因子、JCR/SSCI 分区、中科院分区、JCI、ESI、预警和等级指标。 当用户提到“搜文献”“找论文”“文献检索”“search papers”“find papers”“literature search” “查一下有没有相关研究”“帮我找几篇参考文献”“看看别人怎么做的”“别人怎么写” “Methods…
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/capability-routing.md`, `references/cli-contract.md` and `references/management-layer.md`).
It sits in Research & Science, covering Academic paper search. It works with Semantic Scholar, arXiv, Model Context Protocol and PubMed. The repository describes itself as: Agent-friendly CLI for academic paper, journal metric search and paper download. The licence is MIT.
When your agent uses it
- Tasks that involve Academic paper search
Example prompts
- “search papers”
- “find papers”
- “literature search”
- “/paper-search”
Requirements
- Node.js
- A credential in EASYSCHOLAR_KEY
- A credential in SEMANTIC_SCHOLAR_API_KEY
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- 先做 metadata_search：检索和核验文献条目，确认题名、作者、年份、期刊、DOI、PMID/PMCID、URL、摘要线索和相关性。
- 用户确认条目或任务明确需要 PDF 后，再做 pdf_discovery：下载选中的已核验条目；下载失败项记录原因，不阻塞其他条目。
What it can do on your machine
Read from SKILL.md and the folder at commit d202649. 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:
npmgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and git, 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 these keys or tokens, usually read from environment variables:
EASYSCHOLAR_KEYSEMANTIC_SCHOLAR_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Paper Search loads about 1.1k tokens when it runs, and up to ~6.6k if it reads all its reference files. Until then it costs about 203 tokens; SKILL.md has 242 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.

- description
- 学术文献检索与论文获取调度器，基于 paper-search CLI，而不是 MCP server。 用于：搜索论文、查找相似研究、做文献综述初筛、验证 PMID/DOI、下载论文 PDF、 调用 Crossref/OpenAlex/PubMed/PMC/Europe PMC/arXiv/bioRxiv/medRxiv/Semantic Scholar/CORE/OpenAIRE/DBLP/ACM/USENIX/OpenReview/IACR 等来源， 使用 Semantic Scholar Open Access snippet 索引检索论文正文片段中的方法学细节， 通过 Semantic Scholar Graph API 查询已知论文的施引文献和参考文献， 以及通过 EasyScholar 查询期刊影响因子、JCR/SSCI 分区、中科院分区、JCI、ESI、预警和等级指标。 当用户提到“搜文献”“找论文”“文献检索”“search papers”“find papers”“literature search” “查一下有没有相关研究”“帮我找几篇参考文献”“看看别人怎么做的”“别人怎么写” “Methods 里怎么做的”“Methods 写法”“方法学写法对照”“下载论文 PDF” “验证 PMID”“验证 DOI”“正文片段检索”“snippet search”“方法学细节检索” “影响因子”“IF”“JCR 分区”“中科院分区”“期刊分区”“期刊等级” “目标期刊指标”“journal metrics”等任务时使用。 此 skill 只负责指导 agent 调用 paper-search CLI；API key 必须通过 paper-search setup、 paper-search config、.env 或环境变量配置，绝不要写入 Skill 文件。
Paper Search CLI
你是学术文献检索调度器。本 Skill 是 Routing Skill：负责把用户意图路由到 paper-search CLI，并维护证据、密钥和下载边界。优先通过 paper-search CLI 完成论文检索、元数据核验、施引/参考文献扩展、正文片段检索、期刊指标查询和 PDF 获取；不要把本 Skill 当作密钥、cookie、账号或下载策略的存储位置。
Reference 读取规则：
- 需要确认安装、配置、doctor、smoke、Skill 同步或健康状态时，读
references/management-layer.md。 - 需要在搜索、期刊指标、PDF 获取、正文片段检索之间做路由时，读
references/capability-routing.md。 - 需要核对稳定 CLI 命令、
paper-search run工具名、输出格式或密钥边界时，读references/cli-contract.md。 - 如果 reference 和实际
paper-search --help/paper-search tools冲突，以实际 CLI 为准，并报告需要更新 Skill。
快速自检
第一次使用、环境不确定，或用户问“现在能用哪些能力”时：
command -v paper-search
paper-search doctor --pretty需要给用户一份可读健康报告时：
paper-search doctor --format text安装缺失时先说明缺失；用户要求安装时再执行：
npm install -g paper-search-cli
paper-search setup
paper-search doctor --pretty用户问“如何更新”、安装后怀疑 Skill 过期，或 doctor/skills status 显示 Skill 不同步时，先区分包本体更新和 Skill 同步；不要只运行 skills update。完整流程查看 references/management-layer.md 的 Package Update And Capability Setup。
普通用户更新：
npm install -g paper-search-cli@latest
paper-search skills update --targets agents --pretty
paper-search doctor --pretty本地维护者更新：
git pull
npm install
npm run build
npm install -g .
paper-search skills update --targets agents --pretty
paper-search doctor --pretty缺少 API key 或 email 时，不要让用户在聊天里发送密钥；提示用户用 paper-search setup 或 paper-search config 在本机配置。
功能地图
本 Skill 只有五个文献主功能。doctor、smoke、config、skills 是管理层命令，不属于文献任务本身。
| 用户意图 | 能力名 | 首选入口 | 关键边界 |
|---|---|---|---|
| 搜论文、找相关研究、验证 DOI/PMID、做文献初筛 | metadata_search | paper-search search 集成入口 / paper-search run search_* 精确工具入口 | 只返回和核验论文元数据；Sci-Hub 不属于搜索源 |
| 查询已知论文的施引文献或参考文献 | citation_expansion | paper-search run get_paper_citations / paper-search run get_paper_references | 需要已知 paperId、DOI 或 arXiv ID；不是关键词检索 |
| 查影响因子、JCR/SSCI/中科院分区、JCI、ESI、预警、期刊等级 | journal_metrics | paper-search journal-metrics / paper-search run query_journal_metrics | 这是期刊指标查询，不是论文检索；需要 EASYSCHOLAR_KEY |
| 获取或下载已确认论文的 PDF | pdf_discovery | paper-search download / paper-search run download_with_fallback | 先核验论文身份，再下载；Sci-Hub 是默认开启的最后 fallback |
| 在论文正文片段中找 Methods/参数/写法线索 | body_snippet_search | paper-search run search_semantic_snippets | 查 Semantic Scholar OA snippet 索引；需要 SEMANTIC_SCHOLAR_API_KEY；不是完整全文解析 |
默认工作流
开放式文献任务使用 Two-Stage Paper Workflow：
- 先做
metadata_search：检索和核验文献条目，确认题名、作者、年份、期刊、DOI、PMID/PMCID、URL、摘要线索和相关性。 - 用户确认条目或任务明确需要 PDF 后，再做
pdf_discovery：下载选中的已核验条目；下载失败项记录原因，不阻塞其他条目。
Direct Paper Request 可以跳过广泛发现：用户给出单个 DOI、PMID、PMCID、arXiv ID 或已核验清单并明确要求下载时，先核验目标身份，再进入下载。
验证与输出边界
关键论文输出前尽量验证：
paper-search run search_pubmed --arg query="37654321[PMID]" --arg maxResults=1 --pretty
paper-search run get_paper_by_doi --arg doi="10.xxxx/xxxxx" --pretty
paper-search run search_crossref --arg query="full paper title" --arg maxResults=3 --pretty规则：
- 不凭模型记忆编造 PMID、DOI、期刊、年份或作者。
- PMID 必须能被 PubMed 查询确认；DOI 必须能被 DOI 查询或 Crossref/OpenAlex/Semantic Scholar 结果支持。
- 同一论文的 PMID、DOI、题名、第一作者和年份应一致；不一致时标记为可疑。
config/doctor输出应视为已脱敏，但不要复述、保存或写入任何原始密钥。
常见失败处理
| 场景 | 处理 |
|---|---|
| CLI 不存在 | 提示安装 npm install -g paper-search-cli |
| API key 缺失 | 提示运行 paper-search setup；不要索要或保存 key |
| EasyScholar key 缺失 | 提示运行 paper-search setup EASYSCHOLAR_KEY；不要让用户在聊天中发送 SecretKey |
| 429 限流 | 降低 --max-results，换平台，或提示配置可选 key |
| 0 结果 | 放宽关键词，换英文同义词，换平台，或用 --sources 扩展 |
| 下载失败 | 优先开放获取来源和 download_with_fallback，报告失败原因 |
| 用户要求完整正文 | 先下载 PDF；再交给当前环境可用的 PDF/MinerU 解析流程 |
不属于本 Skill 的事
- 不管理 Zotero、Obsidian 或其他文献库。
- 不写论文正文，不做语言润色。
- 不把 API key、token、cookie 写入 Skill、README 或回复。

Can I use Paper Search 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 dr-dumpling/paper-search-cli --skill paper-search -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/paper-search, .gemini/skills/paper-search, .github/skills/paper-search and .opencode/skills/paper-search in your project.
What does Paper Search need to run?
Going by SKILL.md and its folder, Paper Search needs the command-line tools its instructions call (npm and git) and credentials named EASYSCHOLAR_KEY and SEMANTIC_SCHOLAR_API_KEY. Our summary lists: Node.js; A credential in EASYSCHOLAR_KEY; A credential in SEMANTIC_SCHOLAR_API_KEY.
Does Paper Search access the network?
SKILL.md contains no URLs. Its commands use npm and git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Paper Search safe to install?
