  "instructions": "NameWheel picks names and options at random, fairly. Use spin_wheel whenever the person wants something chosen at random (a student to answer, who goes first, a winner among friends, a decision); the chat shows the wheel spinning to the result. make_teams splits a list into random teams. When other people must be able to check the result later, use certified_draw: it publishes the title, every entry and the winner on a permanent public proof page, so say that to the person before running it. verify_draw checks any certified draw from its code or link. namewheel://truespin explains how certified draws work. certified_draw, freeze_list and my_draws need a connected NameWheel account (free); everything else works without one.",

Use it when the result must be provable to other people: a class prize, a team decision, a draw announced to a group.
