academic-search

academic-search is a skill for Claude Code, Codex from ustc-ai4science/academic-search. It costs 88 tokens per session (1,995 once invoked), scanned A, original, MIT.

A research tool for finding academic papers and collecting structured information about them. It works with sources such as arXiv, Semantic Scholar, PubMed, OpenAlex, and Google Scholar; bioRxiv is an online archive for biology research papers shared before formal peer review.

In plain words
What is it for?
Finding papers by topic or author, reviewing literature, checking citation counts and PDF availability, and exporting references such as BibTeX or RIS.
Why use it?
It reduces the work of searching across research databases, checking citations and open-access PDFs, and organising paper details.

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

academic-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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

按用户要求检索、筛选并交付可追溯的学术资料。优先官方 API 和论文来源;浏览器用于动态页面、交互或当前 API 无法满足的字段。

任务范围与完成标准

从请求确定学科、论文范围、年份、数量和所需字段;只有影响结果且无法合理推断的缺项才询问。开放式选题可先轻量检索、筛选,再补充核心论文;用户已经要求完整元数据、摘要、BibTeX 或下载时,直接完成相应步骤,不因“两遍策略”再次要求确认。

完成标准是所需记录、字段和文件均已交付,或逐项说明未完成部分的证据与原因。工具返回成功、页面加载完成、URL 看起来像 PDF 都不能单独证明任务完成。

学科路由与来源

读取与任务对应的学科 profile,跨学科任务以核心学科为主,并用 OpenAlex / Crossref 等补充。

检索与核验

  1. 根据研究问题选择互补查询词、受控词表与文献类型。记录实际查询、筛选条件和检索时间;按相关性及用户目标排序。CCF 只用于适用的 CS 任务,其他学科遵循 profile;分级需注明来源和版本。
  2. 轻量筛选可暂不拉完整摘要;完整元数据任务应继续补齐已要求的字段。论文表明确区分搜索片段、摘要与全文证据。
  3. metadata-schema 输出。需要交付或复用 JSON 记录时,按 academic-records 运行可执行校验与保守去重:DOI/arXiv/PMID 等精确标识可归组,规范化后标题完全相同只产生待核对候选。预印本与正式版本保留对应关系,勿静默合并不同研究。
  4. 引用数保留平台、数值、检索时间和来源;不同平台的计数分别保存,不求和、不把较大值当唯一真值。缺失字段用空值及原因,不补造。
  5. API 429 只说明当前请求被限流,不能确定会话配额永久耗尽。遵守有效的 Retry-After,无提示时有界退避;同一请求默认最多 2 次重试、总等待预算 30 秒,预算不足则停止该来源并记录限制。并行任务共享平台请求预算;参数详见 API cookbookS2 经验

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.
