video-downloader

Downloads videos from YouTube, Bilibili, Douyin, Xiaohongshu, Kuaishou, Twitter/X, Weibo, Vimeo, TikTok, and 1700+ other sites to local disk. Handles per-platform quirks (Bilibili login for 720P+, Xiaohongshu xsec_token, custom parsers for Douyin/Kuaishou). Use when the user asks to download, save, grab, rip, or archive a video, or provides a video URL with intent to save it locally.
