+
+Hand off to a fresh session.
+
+User's handoff message (if any): $ARGUMENTS
+
+Execute these steps in order:
+
+1. Ask the user: "Ready to hand off? This will restart the session. (y/N)"
+   - If the user says no or doesn't confirm, stop here. Do NOT run gt handoff.
+   - Only proceed if the user explicitly confirms with 'y' or 'yes'.
+
+2. If user provided a message, run the handoff command with a subject and message:
+   `gt handoff -y -s "HANDOFF: Session cycling" -m "USER_MESSAGE_HERE"`
+
+3. If no message was provided, run the handoff command:
+   `gt handoff -y`
+
+Note: The new session will auto-prime via the SessionStart hook and find your handoff mail.
+End watch. A new session takes over, picking up any molecule on the hook.
