What This Skill Does

Command-line tool that generates summaries from URLs, local files (PDFs, images, audio), and YouTube links using AI models from OpenAI, Anthropic, xAI, or Google. Supports configurable summary length, JSON output, and fallback extraction services.

Replaces manually reading or transcribing long-form content by producing concise, customizable summaries from multiple input types with a single CLI command.

When to Use It

  • Summarize a long web article to get key points quickly
  • Extract a short summary from a PDF report without opening it
  • Get a text summary of an audio recording or podcast episode
  • Summarize a YouTube video's content without watching it fully
  • Generate a machine-readable JSON summary for further processing
  • Create a brief overview of an image or scanned document
