By name: jj description: "Use jj (Jujutsu) for local version control instead of git. Activate when: the repo has a .jj/ directory, the user or project config mentions jj, the user says 'use jj', or any version control operation is needed in a jj-managed repo."
jj (Jujutsu) — Version Control for Agent Workflows
UTILITY SKILL for local version control. jj coexists with Git: use jj locally; the remote is standard Git.
USE FOR
- Local version control in repos with a
.jj/directory - Committing, branching, rebasing, splitting, or undoing changes with jj
- Agent-assisted workflows requiring change-by-change iteration
DO NOT USE FOR
- Repos without
.jj/— use git instead - Production CI/CD pipeline configuration
- Advanced jj features beyond common operations (use
jj help)
Execution Skeleton
- Detect:
test -d .jj. If absent, do not activate. - Use jj commands for all local VCS operations.
- For workflows and remote interaction, see reference modules.

- workflow-patterns: Five agent workflow patterns (start task, interrupt/resume, split, skeleton planning, undo)
- remote-and-caveats: Git bridge, bookmarks, push, cleanup, common mistakes, advanced help
