# Advanced Jujutsu (jj) The everyday flow and safety rules live in CLAUDE.md; describing and splitting changes lives in the `commit` skill. This is the deeper reference for what neither of those covers. jj's CLI moves faster than these notes, so verify against `jj --help` and `jj <command> --help` before acting. Treat this skill as orientation, not ground truth. ## Mental Model - `@` — the working copy (current change) - `@-` — parent of `@` - Changes auto-amend: editing files updates `@` in place, no staging - `jj squash` folds `@` into its parent (`--into <rev>` targets any ancestor) ## Diffs with Filesets `jj show` does not accept path arguments — use `jj diff`. Filesets support glob and set operations: ```bash jj diff -r @- # full parent diff jj diff -r @- path/to/file # one file jj diff -- 'glob:"bin/*" ~ glob:"bin/,special"' # glob minus exclusion ``` ## Non-interactive Split `jj split -i` needs an editor. For scripted splits, use `--tool true` — the `true` command exits 0, accepting the file list as given: ```bash jj split --tool true -m "Extract feature" -- \ 'glob:"path/to/file1"' 'glob:"path/to/file2"' ``` Remaining changes stay in a follow-up working copy change. ## Advancing Bookmarks After finalizing work, move the nearest ancestor bookmark forward: ```bash jj bookmark advance # closest bookmark(s) → @ ``` See `jj bookmark advance --help` for `--to` and other targeting.
