## What it is
Hunk is a review-first terminal diff viewer (TUI) for reviewing complete changesets from Git, Jujutsu, and Sapling, with syntax highlighting, split/stack layouts, and themes. It renders inline AI/agent annotations beside the code they explain and supports pager, difftool, and extension workflows.

## Use cases
- review agent-authored code changes in the terminal
- view git diffs with syntax highlighting and split view
- use as a git pager or difftool
- read inline AI agent comments next to the code they explain
- review working tree, commits, stashes, and patches
- navigate large multi-file changesets with keyboard shortcuts
- customize diff viewer themes and layout

## When to choose
- you review AI/agent-generated changesets and want rationale beside the code
- you want a fast, modern terminal diff viewer with themes and mouse support
- you need a git pager/difftool replacement with a multi-file review stream
- you use Git, Jujutsu, or Sapling and want a unified review UI

## When to avoid
- you need GUI or web-based code review with PR workflows (e.g. GitHub review UIs)
- you only need plain unified diff output in scripts
- you require IDE-integrated diff tooling rather than a terminal app
