PR Briefing

Research a pull request and present a structured, progressive-disclosure briefing. The goal is to bring the reader from zero context to full understanding in one pass — shallow enough to skim, deep enough to act on.

Prerequisites

Before starting, verify:

• gh CLI is installed and authenticated (gh auth status)
• git is available and the working directory is inside a repository

If any tool is missing or not authenticated, guide the user through setup before proceeding.
