通用视频下载工具，支持 YouTube、B站、抖音等主流平台。使用 yt-dlp 下载视频，自动选择分辨率、合并音视频、清理文件名。

This skill appears to do exactly what it says: call yt-dlp and ffmpeg/ffprobe to download and (if needed) merge video/audio, sanitize filenames, and return a local path. Before installing: ensure you are comfortable allowing the agent to run yt-dlp and ffmpeg on your host (they will access the network to download media and write files to the output directory or a temp folder); verify brew is available on your platform (or provide the binaries by other means); note that ffprobe is invoked (it normally ships with ffmpeg); and remember downloading copyrighted content may violate laws or terms of service. The skill does not upload files itself, but combining it with a separate “send” skill would transmit files — be cautious about downstream skills. If you want extra assurance, review the included scripts/video_downloader.py source locally to confirm behavior and test in a restricted environment.

Type: OpenClaw Skill Name: video-downloader-skill Version: 1.0.1 The video-downloader skill is a legitimate utility for downloading media using yt-dlp and ffmpeg. The Python script (scripts/video_downloader.py) follows security best practices by using subprocess.run with argument lists to prevent shell injection and includes filename sanitization. No indicators of data exfiltration, malicious execution, or prompt injection were found.
