Jujutsu (jj)

Workflow

Float on main. The working copy sits directly on main@origin. Manual changes are committed and pushed to main. Most work goes through goals, so you periodically pull from main to pick up completed goal work.

1. Start fresh: jj git fetch then jj new main@origin
2. Do work: Make changes, commit as needed
3. Push to main: Push directly to main (no bookmarks, no PRs)
4. Pull updates: jj git fetch then jj rebase -d main@origin to pick up goal work

CRITICAL Rules

• "All files" means ALL files - When told to commit, restore, or rebase "all files", include every modified file in the working copy. Never selectively exclude files. The working copy is the source of truth.
• No bookmarks - Push directly to main, no feature branches
• No PRs - All work lands on main directly

Starting Work

jj git fetch
jj new main@origin

This puts you on a fresh commit with main as parent. All your work builds from here.

Committing

When user says "commit", use jj commit -m "msg":

jj commit -m "Add feature X"

Commits stack automatically. After 3 commits you have: main → A → B → C (@)

Pushing to Main

Move the main bookmark forward to your latest commit, then push:

jj bookmark set main -r @-
jj git push --bookmark main

@- is the parent of the working copy — your most recent jj commit. If you have uncommitted work in @, commit first.

Pulling Updates

When goals complete and land on main, pull their work:

jj git fetch
jj rebase -d main@origin

Squashing (Permission Required)

NEVER squash without explicit user permission.

jj edit <revision>
jj squash -m "Combined message"

Recovery

All operations are logged:

jj op log
jj op restore <operation-id>

Common Commands

Key Concepts

• Working copy (@): Always a commit being edited
• main@origin: The remote main branch — your base and push target
• Float on main: Work sits on top of main, pushes go directly to main
