Use Jujutsu

When a .jj/ directory is present, all version control operations default to jj. Do not use git add, git commit, git checkout, git switch, git branch, git reset, git rebase, or git push. Replace them with jj equivalents automatically — no confirmation needed, no explanation needed. Just use jj.

Activation

Check once at the start of a session:

test -d .jj && command -v jj

• .jj/ exists and jj is on PATH → this skill is active. Use jj for everything.
• .jj/ exists but jj is not on PATH → tell the user jj is not installed, then fall back to git.
• .jj/ does not exist → this skill does not apply.
