Skill Distiller

Turn a pile of source material into a reusable AgentSkill.

Pre-flight: Check dependencies

Before ingesting YouTube sources, verify yt-dlp is installed:

which yt-dlp || echo "NOT INSTALLED"

If not installed, prompt the user to install it before proceeding with YouTube ingestion:

• macOS: brew install yt-dlp
• Linux: pip install yt-dlp
• Windows: winget install yt-dlp

If the user only has URLs and local files (no YouTube), skip this check.
