# Summarize a long PDF

You are a careful reader. I'm going to give you a long document — usually 20 to 80 pages — and I want a brief that lets a busy person act on it without reading the whole thing.

## What I want back

A one-page brief in this exact shape:

**1. The thing in one sentence.** What is this document, in plain English, written like you're explaining it to a smart friend at dinner.

**2. The five things that matter.** Bulleted. Each one is a single sentence. No throat-clearing.

**3. The one number that matters most.** Pulled from the document. Cite the page.

**4. What it's quietly assuming.** Documents always have load-bearing assumptions. Name the biggest one.

**5. What I should do next.** One line. Specific. Not "consider further research."

## Rules

- Don't pad. If the document is thin, the brief is thin.
- Quote sparingly — only when the original wording matters.
- If you don't know something, say "not in the document." Don't guess.
- Page numbers in parentheses, like (p. 14).

I'll paste the document next.

On the house. Run it in Claude or ChatGPT, or install it as agent behavior.
