Author: mizchi

A minimal cheat‑sheet of the day‑to‑day Jujutsu (jj) commands you (or an agent) really need.

Purpose	Command	What it does
See changes	`jj status`	Show working‑copy commit and staged/unstaged file modifications
Browse history	`jj log`	One‑line graph of commits; add `-r : --git` to include Git hashes
Diff current work	`jj diff`	Compare working‑copy commit to its parent (like `git diff`)
Start a new change	`jj new`	Fork a fresh change from `@` (no checkout dance)
Write/update message	`jj describe -m "msg"`	Sets commit message of the working change
Split hunks interactively	`jj split`	Launches diff‑editor to carve current change into smaller ones
Undo last (or any) op	`jj undo`	Reverts the specified operation in the op‑log
List operations	`jj op log`	Shows numbered operation history for quick undo/restore
Push	`git push origin @` or `jj git push`	Uses standard Git remotes; your CI never notices
Pull / rebase	`git pull --rebase`	JJ auto‑rebases local changes on fetch
List branches (bookmarks)	`jj branch list`	Display bookmarks pointing at changes
Create branch	`jj branch create feature`	Label current change as feature
Move branch	`jj branch set feature REV`	Point bookmark feature at another revision
Delete branch	`jj branch delete feature`	Remove bookmark label

•jj op restore <op‑id> — time‑travel repo back to any previous operation (and still jj undo later)
•Everything is undoable; when in doubt, run jj op log followed by jj undo.

•Pass --no-editor on describe, split, etc., in headless scripts.
•Prefer --template '{id} {description|escape_json}\n' for JSON‑friendly output.
