Description

Extracts subtitles from YouTube videos and generates summaries. Use when users provide YouTube URLs with requests like "summarize this video" or "explain this content".

Setup

  1. Create script at 
    {baseDir}/transcript_extract.py
    with provided code
  2. All libraries are already installed in the skills folder.
  3. Therefore, no additional action is required to run Python files.

Usage

When receiving a YouTube URL:

  1. Executes: 
    python3 {baseDir}/transcript_extract.py "<YOUTUBE_URL>"
  2. Captures output between 
    [TRANSCRIPT-START]
    and 
    [TRANSCRIPT-END]
  3. Uses LLM to generate summary from raw transcript text

Configuration

script_path: "{baseDir}/transcript_extract.py"
supported_languages: ["ko", "en"]

Example

Input:

https://youtu.be/dQw4w9WgXcQ
(with "summarize this" context)

This video contains the iconic Rickroll meme track by Rick Astley. The lyrics revolve around themes of loyalty and commitment, featuring the artist's signature bassline and 80s production style. Despite its simple lyrics, it remains one of YouTube's most enduring viral pranks.

Notes

  • Handles both manually created and auto-generated subtitles
  • Falls back to English if Korean subtitles aren't available
  • Returns error messages if no transcript exists or URL is invalid
