bilibili-cli Skill

Authentication

Most read commands work without login. Subtitles, favorites/following/watch-later/history, feed, and interactions require login.

bili status                    # Check if logged in
bili login                     # QR code login (if not authenticated)

Authentication auto-detects local browser cookies (Chrome/Firefox/Edge/Brave). If cookies are found and valid, no manual login needed.
