Instructions for using Jujutsu, a version-control system compatible with Git. It explains safe commands for repositories that use Jujutsu, including repositories with a detached Git HEAD.

Use it for repository status, history, descriptions, rebasing, squashing, restoring, abandoning changes, and other version-control work in a Jujutsu repository.

It helps prevent raw Git operations from damaging Jujutsu's commit and working-copy model.

jujutsu — Skill for Claude Code by danverbraganza

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add danverbraganza/jujutsu-skill --skill jujutsu

Clone the repo

git clone --depth 1 https://github.com/danverbraganza/jujutsu-skill

Made for: Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.03239
Opus 5	$0.00036	$0.01620
Sonnet 5	$0.00014	$0.00648
Haiku 4.5	$0.00007	$0.00324

Security

Grade C, and why

jujutsu scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- Don't `rm -rf` a workspace directory without also running `jj workspace forget <name>`.

How it starts

The opening of the file, as written. The whole thing — 416 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Jujutsu (jj) Version Control System

This skill helps you work with Jujutsu, a Git-compatible VCS with mutable commits and automatic rebasing.

Tested with jj v0.37.0 - Commands may differ in other versions.

Important: Automated/Agent Environment

When running as an agent:

Always use --no-pager to prevent commands from opening an interactive pager (like less), which will hang the agent:

# Always use --no-pager on commands that produce output
jj --no-pager log          # NOT: jj log
jj --no-pager diff         # NOT: jj diff
jj --no-pager show <id>    # NOT: jj show <id>

Always use -m flags to provide messages inline rather than relying on editor prompts:

# Always use -m to avoid editor prompts
jj desc -m "message"      # NOT: jj desc
jj squash -m "message"    # NOT: jj squash (which opens editor)

Editor-based commands will fail in non-interactive environments.

Verify operations with jj st after mutations (squash, abandon, rebase, restore) to confirm the operation succeeded.

Core Concepts

The Working Copy is a Commit

In jj, your working directory is always a commit (referenced as @). Changes are automatically snapshotted when you run any jj command. There is no staging area.

There is no need to run jj commit.

Commits Are Mutable

CRITICAL: Unlike git, jj commits can be freely modified after creation. You can update descriptions, squash changes, rebase, and absorb — all without creating new commits. See "Essential Workflow" below for the recommended working pattern.

Change IDs vs Commit IDs

Change ID: A stable identifier (like tqpwlqmp) that persists when a commit is rewritten — prefer these when referencing commits
Commit ID: A content hash (like 3ccf7581) that changes when commit content changes

Revsets

jj uses a revset language to select commits in commands. Common revsets:

@ — the working copy commit
@- — the parent of the working copy
::@ — all ancestors of @
@:: — all descendants of @
trunk()..@ — commits between trunk and @ (your branch)
bookmarks() — all commits with bookmarks

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

jujutsu is a skill published in the GitHub repository danverbraganza/jujutsu-skill (73 stars, last pushed 2mo ago), licensed MIT. It adds 71 tokens to every session and 3,239 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
