Authenticated Paper Fetcher

Download academic PDFs through authorized institutional access, library proxies, local browser profiles, or cloud browser sessions without storing credentials. 通过学校/机构已授权访问、图书馆代理、本地浏览器登录态或云端浏览器会话下载学术 PDF，不保存账号密码。 Authenticated Paper Fetcher helps Codex retrieve individual academic articles, papers, and book chapters from publisher platforms such as SpringerLink, ScienceDirect, Wiley, Taylor & Francis, JSTOR, and library proxy systems including EZproxy, OpenAthens, and Shibboleth. Use it when the user already has legitimate access and wants Codex to fetch the PDF, preserve metadata, and keep the workflow reproducible. Authenticated Paper Fetcher 用于让 Codex 通过用户已有的合法访问权限下载单篇学术论文、文章或书籍章节，支持 SpringerLink、ScienceDirect、Wiley、Taylor & Francis、JSTOR 等出版社页面，以及 EZproxy、OpenAthens、Shibboleth 等图书馆/学校认证入口。适用于“我已经能登录学校账号下载，但希望 Codex 代为拉取 PDF、保存元数据、整理到项目目录”的场景。
