A practical Jujutsu guide for Git users who work with AI coding agents

Juju-chu! is a hands-on field guide to Jujutsu (jj), a Git-compatible version control system, written for developers who code with AI agents. By the end of the book, you won't just understand how Jujutsu works—you'll be ready to use it in your everyday development work.

Why Jujutsu? Git was designed for humans who stage and commit carefully, when ready.

AI coding agents broke that rhythm: they generate and rewrite large amounts of code in seconds, while you're still deciding what to `git add`. Forgotten commits, tangled diffs too large to split cleanly, and the constant stop-and-go of staging while your agent races ahead—these aren't carelessness. They're a structural mismatch.

Jujutsu resolves that mismatch. Commits happen automatically, so there's nothing to forget. Every operation can be undone, giving you an absolute safety net. Conflicts don’t stop you—Jujutsu records them as part of history without blocking, so you can resolve them whenever you’re ready. And since Jujutsu speaks Git under the hood, you can adopt it on your own while the rest of your team stays on Git.

Inside the book:

A hands-on tour to get a feel for Jujutsu right away
Jujutsu's mental model and how it differs from Git's—changes, bookmarks, the evolution log, and the operation log
Practical AI-agent workflows: coordinating AI agents with jj, reshaping AI-generated changes, running agents in parallel across workspaces, and pushing to GitHub
Q&A and troubleshooting for the questions and edge cases you’ll hit in real projects

The book is written as a dialogue between a senior and a junior engineer—playful on the surface, practical underneath. If you already use Git and work (or plan to work) with agents like Claude Code or Codex CLI, this book is for you. This book assumes you already know the basics of Git.
