Extract transcripts from YouTube videos via the YouTube caption system.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# YouTube Skill
Extracts the transcript (captions) from a YouTube video using the YouTube
caption system — no API key or audio download required. Optionally uses a
vision-capable LLM to produce a structured summary (Overview, Topics,
Key takeaways) before the raw transcript.
## Setup
```bash
pip install youtube-transcript-api
```
## Standalone usage
**Transcript only** (no LLM required):
```python
import asyncio
from synthadoc.skills.youtube.scripts.main import YoutubeSkill
skill = YoutubeSkill() # no provider — returns raw timestamped transcript
async def main():
result = await skill.extract("https://www.youtube.com/watch?v=dQw4w9WgXcQ")
print(result.text) # "[0:00] text [0:04] text ..."
print(result.metadata) # {"video_id": "...", "title": "...", "url": "..."}
asyncio.run(main())
```
**With LLM summarization** (pass any provider that implements `complete()`):
```python
skill = YoutubeSkill(provider=my_provider)
result = await skill.extract(url)
# result.text contains:
# ## Executive Summary
# <Overview / Topics / Key takeaways>
#
# ## Transcript
# [0:00] ...
```
The provider must implement:
```python

How to install
mdr add axoviq-ai/synthadoc/youtube@sha256:de132f4e8eabc44bThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
