The skill is a real literature-search integration, but it asks the agent to register users, handle payments, store identifiers, and try broad PDF retrieval methods including anti-hotlink workarounds.
Review this carefully before installing. Use it only if you are comfortable sending your email, search requests, document identifiers, and payment-order details to SmartLib/Alipay flows, and avoid using the automated PDF retrieval path for content where you do not have rights or clear open-access permission. Confirm any paid plan deliberately and verify where downloaded files will be written.
