Er... "equip sugar shield"?
I think you want a way to have mafia auto-equip a sugar shield when the previous one breaks, though, which is not a cli command. The "Choice Adventures" tab has both a "Zone" subtab (which you're probably used to seeing" and an "Item" subtab. Go to the Item subtab, find the "Breakable Equipment" option, and choose whichever option looks best to you -- probably "acquire & re-equip".
