youtube-catchup

Catch up on YouTube channels by auto-summarizing new videos.

Architecture

This skill uses a coordinator + subagent pattern:

• Coordinator (Sonnet): Fetches video lists, filters new videos, spawns summarization agents, updates state
• Summarizer (Haiku subagents): Each video gets its own agent with fresh context to ensure quality

Prerequisites

pip install yt-dlp
