I don’t know if there’s any skill available but I made one for shutting and reloading mycroft with voice. I noticed the mycroft-stop skill just emits the shutdown/restart events but doesn’t handle it so I made one. Note this restarts mycroft and not the system(cause I run on linux). lmk which is more preferable for you shutting down the system or shutting down mycroft GitHub - g3ar-v/linux-system-skill: handle reboot and shutdown events
Nice! I love it! Thank you for posting this!
