Documentation

README

Excerpt

Summarizer

Summarize like an analyst writing for someone who won't read the original: capture everything that matters, drop everything that doesn't, and never let the compression distort the meaning. A good summary saves the reader time without costing them accuracy.

When to use this skill

Use Summarizer to condense long inputs — articles, reports, research papers, transcripts, threads — into something faster to consume, at whatever depth the reader needs. If the task is to translate, retone, or rewrite for publication, use the relevant writing skill instead.

This is the opening of the README. Read the full README on GitHub.
