Overview Implementation Examples History

name: jujutsu description: Jujutsu (jj) Git-compatible VCS. Use for any version-control work (status/diff/commit/branch/rebase/merge/etc.).

Jujutsu (jj)

Rule

If you think “git”, use jujutsu.

When to trigger

Use this skill whenever version control is in play, even if the user doesn’t say “git”.

Tripwires:

  • Commands: status, diff, log/history, add/stage, commit, branch, merge, rebase, stash, tag, checkout/switch, cherry-pick, revert, reset, amend, squash, conflict, pull/push/fetch, clone, submodule, blame, bisect.
  • Terms: staged/unstaged, HEAD, origin/upstream, clean/dirty, detached.

JJ-first policy

  • Prefer jj for VCS writes.
  • If jj is missing, ask to install it or request permission to fall back to git.
  • In colocated repos, avoid mutating with git unless you know what you’re doing (git may appear detached).

Core concepts

  • The working copy is a commit: @ is the working-copy commit, @- its parent.
  • Bookmarks are branch-like pointers: jj bookmark ….
  • Workspaces are git-worktree-like: jj workspace add ….
    • There is no jj workspace use command. To switch, cd into the workspace directory.

Git interop / colocation

  • New repo backed by Git: jj git init <name>.
  • Clone a Git remote: jj git clone <url> [dest].
  • Existing Git repo: jj git init --git-repo=<path> <name>.
  • Colocation controls: jj git colocation status|enable|disable.

Common commands

Inspection:

  • jj status
  • jj log
  • jj diff
  • jj op log

Editing changes:

  • jj new <rev>
  • jj describe [<rev>]
  • jj edit <rev>
  • jj commit

Move/rewrite history:

  • jj squash
  • jj split
  • jj rebase -b <bookmark> -d <dest>

Bookmarks:

  • jj bookmark list
  • jj bookmark create <name> -r <rev>
  • jj bookmark move <name> --to <rev>
  • jj bookmark delete <name>

Undo:

  • jj undo
  • jj redo

Command mapping (git -> jj)

Git Jujutsu Notes
git status jj status
git diff jj diff
git log jj log
git add <path> jj file track <path> JJ auto-tracks edits; use track for new paths.
git restore <path> / git checkout -- <path> jj restore <path> Restores from parent into the working copy.
git commit -m "msg" jj commit -m "msg"
git commit --amend -m "msg" jj describe -m "msg" Edits current change description.
git branch jj bookmark list
git branch <name> jj bookmark create <name> -r @
git branch -d <name> jj bookmark delete <name>
git switch <name> / git checkout <rev> jj edit <rev> Moves working copy to an existing change.
git switch -c <name> jj new + jj bookmark create <name> -r @ Two-step in jj.
git merge <branch> jj new @ <branch> Creates a merge commit with both parents.
git rebase <upstream> jj rebase -b @ -o <upstream> Rebase current branch onto upstream.
git pull jj git fetch + jj rebase -b @ -o <remote-bookmark> Fetch then rebase onto e.g. origin/main.
git fetch jj git fetch
git push jj git push

Workspace switching (correct usage)

  • List workspaces: jj workspace list
  • Add a workspace: jj workspace add <path> [-r <rev>]
  • Forget a workspace: jj workspace forget <path>
  • Switch workspaces by changing directories: cd <path>

Safety notes

  • jj has no “current branch”; bookmarks don’t auto-advance.
  • Avoid interactive flags (like -i) in non-interactive harnesses.
