+        This is intended to be called after switching integrations. Command
+        registration is scoped to the explicit ``agent_name`` argument, but some
+        behavior still depends on the current init-options state (for example,
+        skills-mode handling uses the active ``ai`` / ``ai_skills`` settings).
+
+        Callers should therefore pass the agent that has just been made active

+        current ``ai`` value. This mirrors extension install behavior while
+        avoiding stale default-mode command directories when that active agent
+        is running in skills mode (notably Copilot ``--skills``).
