paper-search

paper-search is a skill for Claude Code, Codex from dr-dumpling/paper-search-cli. It costs 361 tokens per session (1,919 once invoked), scanned A, original, MIT.

A command-line tool for searching academic papers and getting research files. It can work with sources such as PubMed, arXiv, bioRxiv, and Crossref; bioRxiv is a website for sharing scientific papers before formal journal review.

In plain words
What is it for?
Use it to find papers, perform an initial literature-review search, verify a paper’s DOI or PMID, search parts of papers for methods, check journal metrics, and obtain PDFs when available.
Why use it?
It brings paper discovery, metadata checks, similar-study searches, citation expansion, and PDF retrieval into one workflow instead of requiring separate searches across many research websites.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

paper-search scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.mdPackage 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 setuppaper-search config 在本机配置。

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
