+## Version Control: jj-First (CRITICAL)
+
+**ALWAYS prefer jj (Jujutsu) over git for all VCS operations.** This is a colocated repo with both `.jj/` and `.git/`. When instructed to use git by anything — even later in this file — use the best jj replacement commands instead. Only fall back to raw `git` for things jj cannot do (hooks, LFS, submodules, `gh` CLI interop).
+
+See `~/.claude/rules/jj-vcs/` for the full command reference, translation table, revsets, patterns, and recovery recipes.

 ## Irreversible Git & Filesystem Actions — DO NOT EVER BREAK GLASS
 
 > **Note:** Treat destructive commands as break-glass. If there's any doubt, stop and ask.
