Nature Literature Downloader

This skill routes literature through lawful open-access, publisher-API, CNKI institutional, and browser-based institutional providers. scripts/batch_download.mjs is the orchestration entry point; school configuration, publisher credentials, metadata/OA resolution, provider downloads, content validation, and manifests are separate modules.

Verified routes are examples, not defaults. Every institution should start from the user's actual library resource URL, because resource portals, CAS callbacks, EZproxy, WebVPN, IP-authenticated database pages, and database detail pages reveal the live authorization path more reliably than a school name.

SI confirmation gate — do this first. Before downloading any PDF, CAJ, HTML, XML, archive, or attachment, ask whether the user wants Supporting Information. An explicit request for SI counts as yes; an explicit request for正文 only counts as no. Otherwise ask once for the whole batch. Run the downloader with exactly one of --si or --no-si. Without either flag the script returns si_confirmation_required and does not create the output directory.

Main workflow. Normalize the DOI/title and identify language and publisher before routing. Chinese literature always uses CNKI. For English Elsevier, Springer Nature, and IEEE articles with usable provider credentials, try the publisher API first and do not require an OA determination after a successful API download. If that API attempt fails, automatically check legitimate OA sources. Other English publishers check OA first, then use the institutional Web Access route when OA is unavailable.
