name: youtube-transcript
description: Extract transcripts from YouTube videos. Use when the user asks for a transcript, subtitles, or captions of a YouTube video and provides a YouTube URL (youtube.com/watch?v=, youtu.be/, or similar). Supports output with or without timestamps.

# YouTube Transcript
Extract transcripts from YouTube videos using the youtube-transcript-api.
## Usage
Run the script with a YouTube URL or video ID:
```bash
uv run scripts/get_transcript.py "VIDEO_URL_OR_ID"
```
With timestamps:
```bash
uv run scripts/get_transcript.py "VIDEO_URL_OR_ID" --timestamps
```
## Defaults
- **Without timestamps** (default): Plain text, one line per caption segment
- **With timestamps**: `[MM:SS] text` format (or `[HH:MM:SS]` for longer videos)
## Supported URL Formats
- `https://www.youtube.com/watch?v=VIDEO_ID`
- `https://youtu.be/VIDEO_ID`
- `https://youtube.com/embed/VIDEO_ID`
- Raw video ID (11 characters)
## Output
- CRITICAL: YOU MUST NEVER MODIFY THE RETURNED TRANSCRIPT
- If the transcript is without timestamps, you SHOULD clean it up so that it is arranged by complete paragraphs and the lines don't cut in the middle of sentences.
- If you were asked to save the transcript to a specific file, save it to the requested file.
- If no output file was specified, use the YouTube video ID with a `-transcript.txt` suffix.
## Notes
- Fetches auto-generated or manually added captions (whichever is available)
- Requires the video to have captions enabled
- Falls back to auto-generated captions if manual ones aren't available
