Zlib Download

A straightforward way to search and download books from Z-Library and Anna's Archive without leaving your terminal. Handles the preflight checks, credential management, and session token caching so you can search by title, filter by language or format, then download with a single command. The skill auto-falls back between backends when one is down and presents results in a numbered table for easy selection. Works in English and Chinese. You'll need Z-Library credentials or an Anna's Archive API key to actually download anything, but setup is a one-time .env file edit. Good for quickly grabbing technical papers or ebooks when you're already in a Claude session.
