Rimagination/scansci-pdf is an agent-oriented tool that finds and downloads academic papers from sources such as open-access repositories, preprint services, publishers, and institutional access routes. It accepts identifiers or literature lists, saves papers as named PDF files, and can also export citations or convert PDFs to Markdown. Its MCP server and agent plugins let coding agents use these paper-retrieval workflows.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.
git clone --depth 1 https://github.com/Rimagination/scansci-pdfnpx agentmods add skills/rimagination/scansci-pdf/scansci-cnWrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00081 | $0.00960 |
| Opus 5.5 | $0.00032 | $0.00384 |
| Sonnet 5.5 | $0.00016 | $0.00192 |
| Haiku 4.5 | $0.00008 | $0.00096 |
Grade A, and why
scansci-cn 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 2d 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.

ScanSci CN — 中文文献获取与核验
扫描中文文献的合法通道，并给中文清单做标识规范化与下载后校验。不涉及任何镜像绕过或第三方共享账号。

中文 DOI 与标识
- 中文刊常见 DOI 族：
10.3969/j.issn.1000-xxxx.yyyy.nn.nnn(万方系)、10.11897/…、10.13324/…及大量自有前缀。 - 校验用
scripts/cn_resolve.py：全角→半角、空白清理、DOI 提取、ISSN/年份/期号/篇号拆解。 - 知网导出多为
CAJ格式：需 CAJViewer，或机构版页面选 PDF 下载；批量任务应把.caj单独成桶。
下载后核验(必做)
scripts/verify_pdf.py：用 PDF 首页文本对比 Crossref 标题(EN 用词元覆盖率，CJK 用字符二元组 Jaccard)，并检查
撤稿状态(Crossref update-to + OpenAlex is_retracted)。
python scripts/verify_pdf.py --doi 10.1007/s11356-020-11742-8 --pdf paper.pdf
python scripts/verify_pdf.py --dir ./pdfs # 文件名以 DOI 开头的批量核验
建议在 sort 落库前对整批下载跑一次，输出 JSON 里：
match低于阈值 → 疑似下错文章retracted: true→ 从综述证据链剔除
与 sort 流程的衔接
- 清单卫生：中文标题做全角/空白归一(见 cn_resolve.py)
- 分诊：中文 DOI 走机构桶；无 DOI 的中文文献单独成桶(缺DOI)
- 下载：机构登录态 / NCPSSD 人工 / 期刊官网直链
- 核验：verify_pdf.py 全量跑
- 报告：按"来源/许可"分桶(O A/机构/官网/人工)，便于发表偏倚分析
反爬与礼貌
- 知网/万方/维普对高频请求敏感：串行、间隔 ≥2s，单账号单日控制在个人阅读量级。
- 机构 cookie 有时效：批量任务前先用一次小请求探测登录态是否有效。
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.
- 2d ago First seen · 54 lines · 81 tokens per session scan A 562d75645ac4
scansci-cn is a skill published in the GitHub repository Rimagination/scansci-pdf (1,153 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 960 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-23.
