What problem does it solve? Researchers often cannot obtain paper full text because articles sit behind publisher paywalls, require institutional subscriptions, or are scattered across open-access repositories. This Skill routes each paper through lawful download paths automatically and records an auditable manifest of every attempt. ## Core Features & Use Cases - Intelligent routing: Identifies language and publisher, then chooses CNKI for Chinese papers, publisher APIs (Elsevier, Springer Nature, IEEE) when keys exist, open-access sources (PMC, Unpaywall, arXiv), or the user's authenticated institutional browser session as fallback. - Batch downloads with SI support: Downloads PDFs, HTML/XML full text, CAJ files, and optional Supporting Information for DOI lists, exact titles, or topic searches, writing a manifest.json with hashes, routes, and typed failure statuses. - Secure credential handling: Stores publisher API keys and library configuration locally with owner-only permissions, never echoing secrets into logs or manifests. - Use Case: Given a list of 20 DOIs for a literature review, the Skill downloads all legally available PDFs into a project folder, fetches supplements where requested, and reports exactly which papers lacked institutional entitlement. ## Quick Start Ask the agent to download the papers for your DOI list into a project folder, choosing whether Supporting Information should be included.
