+### 3. Auto-Sync Preferences (UserPromptSubmit)
+
+**Trigger:** Before each user message
+**Behavior:** Runs `git pull` in the local clone of this preferences repo. Because `CLAUDE.md` and `preferences/` are symlinked into `~/.claude/`, the pull immediately updates what Claude sees without any manual steps. Silently skips if already up to date or unreachable.
+
+Requires the one-time symlink + clone setup described in this repo's `README.md`.
