- Works in 5 steps: Pull the metadata → Get the transcript → Classify the video → …

- Calls yt-dlp, brew and pip; reaches youtube.com
What it does
Youtube is an agent skill from superhero-tech/super-brain. Captures a YouTube video as a source note and a wiki page. Use when the human drops a video URL, wants a talk or tutorial turned into notes, or asks what a specific video said about a topic.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management. It works with YouTube. The repository describes itself as: Product Builder Second Brain - AI Product Heroes Edition 3. The licence is MIT.
When your agent uses it
- The human drops a video URL
- Tutorial turned into notes
- Asks what a specific video said about a topic
Example prompts
- “Use the youtube skill to capture a YouTube video as a source note and a wiki page. An agent skill from superhero-tech/super-brain”
- “/youtube”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 0922a1a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
yt-dlpbrewpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
youtube.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Youtube loads about 985 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 445 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- youtube
- description
- Captures a YouTube video as a source note and a wiki page. Use when the human drops a video URL, wants a talk or tutorial turned into notes, or asks what a specific video said about a topic.
YouTube Video Summary
Turns a YouTube video into a structured note, then compiles that note into a wiki page in Knowledge.
When to use
- You want a video turned into a clean note with metadata and key ideas
- For tutorials the output is a step-by-step guide, not a summary
Requirements
This skill pulls metadata and subtitles with yt-dlp. Install it once:
brew install yt-dlp # macOS
pip install yt-dlp # everywhere elseWithout yt-dlp the skill still works, just slower: take the video ID from the URL and search the web for the metadata, then ask the human to paste the transcript from YouTube's transcript panel. Say which route you are taking so they know why it takes longer.
How to invoke
/youtube https://youtube.com/watch?v=...- "Make a note from this video: [URL]"
How it works
1. Pull the metadata
yt-dlp --skip-download --print "%(title)s|||%(channel)s|||%(upload_date)s|||%(description).500s" "$ARGUMENTS"If yt-dlp fails: extract the video ID from the URL and use web search.
2. Get the transcript
yt-dlp --skip-download --write-auto-subs --sub-langs "en" --sub-format "vtt" -o "/tmp/yt_transcript" "$ARGUMENTS"Add more languages to --sub-langs when you need them. If it fails, ask the user to paste the transcript from YouTube.
3. Classify the video
- Tutorial/Explainer: walkthrough, demo, how-to -> output a step-by-step guide
- Idea/Opinion: thesis, interview, perspective -> output key ideas plus quotes
4. Generate the note
YAML frontmatter:
---
date: YYYY-MM-DD
title: "Video Title"
author: Channel Name
source: [YouTube URL]
topics:
- topic-1
- topic-2
source_type: video
---This is the frontmatter of the source note that lands in 2-Inbox/ and later 5-Raw/. It is not wiki-page frontmatter - wiki pages use type: concept | entity. Do not copy this block onto the wiki page.
For tutorials:
# Title
## What this covers
[1-2 sentences]
## Step-by-Step
### Step 1: [Action]
[What to click, type, configure. Imperative.]
## Tips & Gotchas
- Practical notes and limitations
## Source
[URL]For ideas/opinions:
# Title
## Key Ideas
- (5-10 key ideas - be specific)
## Summary
[3-5 paragraphs]
## Notable Quotes
> "Quote from the video"
## Source
[URL]What to extract:
- Concrete examples and anecdotes (do not abstract them away)
- Numbers and metrics
- "here is what we actually do" moments - where speakers reveal practice instead of theory
- Contrarian claims
- Tools and products by name
- Metaphors and mental models
- Q&A sections - the best nuggets hide there

5. Save the note and hand it to the ingest
Save the note to 2-Inbox/, then run the ingest skill on it. That skill owns everything downstream: mapping the video against the wiki, writing the pages, linking them, updating the index and log, and archiving the note to 5-Raw/.
Tell the ingest one thing it cannot see on its own: talks are entity-heavy. The speaker, their company and every tool they name by name are entity candidates, and a good talk moves more pages than an article of the same length.
This skill's job ends at a note good enough to compile.
Self-check
- Could someone hold a conversation about this topic reading only my note?
- For tutorials: could someone RUN the workflow without watching the video?
- Did I capture the concrete numbers and metrics?
- Did I catch the Q&A section?
- Did I avoid AI filler words (delve, tapestry, pivotal, foster)?
- Is the note in
2-Inbox/and handed to the ingest, rather than left sitting there?
