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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 2mo 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.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。

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.
