The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes external binaries yt-dlp and ffmpeg via the subprocess.run method. It correctly uses argument lists rather than shell strings, preventing potential command injection vulnerabilities.
[EXTERNAL_DOWNLOADS]: The skill fetches media content from Bilibili's servers. Additionally, the demucs library may download pre-trained weights for its AI models from official, well-known repositories (Meta/GitHub) during the first run of the vocal separation feature.
[DATA_EXPOSURE]: The script interacts with the local file system to save downloaded media, defaulting to a folder on the user's desktop. It also supports passing browser identifiers to yt-dlp for cookie extraction, which is a standard procedure for accessing authenticated or high-definition content from the platform.
