Task alerts for DSH: a system toast when a turn finishes, or when an approval, question or plan review is waiting; a chime rendered on the Windows communications endpoint so the system ducks other media by its own setting and restores it afterwards, without anyone's volume being written; and an optional copy mailed to your phone over SMTP (465 implicit TLS, or STARTTLS where credentials go out only after the upgrade). No runtime dependency: the sound helper is a PowerShell script, the mail client is plain Node.
