PR Brief — AI skill for Claude Code

pr-brief — Claude Code marketplace

An interactive, browser-based PR review workflow for [Claude Code](https://docs.claude.com/en/docs/claude-code/overview). It pulls a pull request via `gh`, asks an Opus agent to group every changed file into features and author a **narrative layer** of "explain pills", and launches a local UI with GitHub-style stacked diffs, click-and-drag multi-line inline commenting, and realtime comment posting.

This repository is a **plugin marketplace**. It ships one plugin: `pr-brief`.

What reviewers get:

• A reviewer-ordered file list (migrations first, tests last) grouped into the features the PR actually contains
• Two parallel narrative layers next to each diff:
  • Purple ✨ explain pills — short AI-authored callouts that connect each block to the broader change
  • Red ⚠ critique pills with a severity score S1–S5 — actual review concerns, optional suggested_change blocks, and a "Use as comment →" button that turns a critique into an inline GitHub comment in one click
• Click-and-drag multi-line inline comments that POST to GitHub in realtime via gh api
• 💬 Inline chat: right-click any selected snippet → a streaming chat panel pops on the right that resumes the same Claude Code session that wrote the brief, so it already has full PR context. (details below)
• Runs locally; the only external call is to the Anthropic API your Claude Code session is already using

Why this exists

Three reasons:

1. I had to review ginormous PRs and I couldn't afford asking folks to break their PRs and stack them.
2. Reviewing PRs is somewhat of finding needles in a haystack — with this I can know the right sequence to look.
3. Reading code isn't always straightforward; you have to connect the dots between files mentally. This facilitates it.
