Real A/B on a PulseTrack iOS listing: my ad hoc baseline blew the subtitle limit by 18 chars and the keyword field by 25 (check_app_store_limits.py exited 1), while the skill's intake-then-validate workflow produced a listing that passed every field (exit 0) and read less generic per its own keyword-stuffing pitfall guide.
