Paper Download is an Agent Skill for documents published in the tsingyuai/scientify repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Download academic papers: arXiv source/PDF by ID, DOI papers via Unpaywall open access. Supports batch download.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

Open your project in Codex.
Copy and paste the prompt below.
Review files and risks before approving any action.

Prompt to paste

Inspect the Agent Skill at https://github.com/tsingyuai/scientify/blob/HEAD/skills/paper-download/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/paper-download, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Paper Download

将论文下载到当前工作目录的 papers/ 下。

arXiv 论文

优先下载 .tex 源文件（可读性远优于 PDF）：

mkdir -p papers/{arxiv_id}
curl -L "https://arxiv.org/src/{arxiv_id}" | tar -xz -C papers/{arxiv_id}

如果 tar 解压失败（部分论文只提供 PDF），回退到 PDF：

curl -L -o papers/{arxiv_id}.pdf "https://arxiv.org/pdf/{arxiv_id}"

arXiv 限速：连续下载时每篇间隔 3 秒（sleep 3）。

DOI 论文（通过 Unpaywall）

查询开放获取链接，有则下载，无则跳过：

curl -s "https://api.unpaywall.org/v2/{doi}[email protected]" | \
  python3 -c "
import sys, json
d = json.load(sys.stdin)
oa = d.get('best_oa_location') or {}
url = oa.get('url_for_pdf') or oa.get('url')
if url: print(url)
else: print('NO_OA', file=sys.stderr)
" | xargs -I{} curl -L -o papers/{doi_slug}.pdf "{}"

{doi_slug} = DOI 中的 / 替换为 _，例如 10.1000/xyz123 → 10.1000_xyz123。非开放获取论文静默跳过，不报错。

批量下载

# 批量 arXiv
for id in 2401.12345 2403.00001 2405.67890; do
  mkdir -p papers/$id
  curl -L "https://arxiv.org/src/$id" | tar -xz -C papers/$id || \
    curl -L -o papers/$id.pdf "https://arxiv.org/pdf/$id"
  sleep 3
done

下载后

下载的论文 ID 应追加到 config.json 的 processed_ids（如果存在）
优先读 .tex 源码而非 PDF（信息更完整，公式可直接提取）
