The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill automatically installs external software dependencies at runtime. It uses pip install for the yt-dlp Python package and system package managers (apt, brew, or choco) to install the ffmpeg binary if they are not already present.
[COMMAND_EXECUTION]: The script scripts/main.py uses the subprocess.run module to execute system-level commands for checking dependencies, performing installations, and running the video download process. High-privilege commands like apt install are executed depending on the host operating system.
[COMMAND_EXECUTION]: User-provided input (the video URL) is passed as an argument to the yt-dlp command-line tool. Although the skill uses list-based subprocess calls to prevent basic shell injection, passing untrusted input to complex CLI tools remains a potential vector for argument injection or exploiting vulnerabilities in the tool itself.
