    Youtube videos to knowledge base

    Example session with this skill installed

    I just watched this video on LLM agents: https://www.youtube.com/watch?v=dQw4w9WgXcQ. Please add it to my knowledge base.

    • Read your context and instructions
    • Compiled the youtube videos to
    • Generated the document

    I've processed the video and updated your knowledge base. No duplicate ID was found, so a new source file was created and the transcript was parsed for concepts and tools.

    Extraction Summary

    • Concepts: Recursive task decomposition, ReAct prompting loops, long-term memory retrieval.
    • Tools: LangGraph, AutoGPT, CrewAI.
    • Action Items: Test the new state-machine approach for multi-agent handoffs.
    • Conflicts: None detected. The content aligns with your existing notes on LLM reasoning.

    Next steps

    1. Review the new Planning Algorithms note to see the extracted architecture diagrams.
    2. Run a connections check since you have now added 6 sources since the last audit.
    3. Check the sources/ file for the timestamped link to the section on "Memory Bottlenecks."

    About this skill

    Most YouTube skills give you one summary per video. After 50 videos you have 50 summaries and still can't find what you learned about a topic. This skill builds a knowledge base instead. Give it a YouTube link, a playlist or a pasted transcript, and it: - Sorts ideas by topic, not by video, into domains and topic notes - Merges genuinely new points into notes you already have, and skips what you already know - Flags real contradictions between sources (and doesn't invent fake ones) - Never processes the same video twice - Handles whole playlists with progress updates - Keeps a source record per video: concepts, tools mentioned, action items - Offers a "connections check" to link related ideas across topics Plain Markdown with relative links: works as an Obsidian vault, in any editor, with any AI model. Includes real example output from two videos, showing the second one merging into the first. Needs an agent that can read and write files (Claude Code, Claude with folder access, Cursor, Codex CLI). Fetches transcripts automatically with a transcript tool, yt-dlp or youtube-transcript-api; otherwise paste the transcript. Recommended transcript tool: TranscriptAPI (transcriptapi.com), which the skill was built and tested with. New accounts get 100 free credits with no card, about 100 videos, and setup instructions are in the README.

    How to install
