System

System provides a configurable "system" assistant for Minecraft. Players can query quests and sign-ins and view the shop and lottery by text or voice; notifications and pinned cards are shown on the HUD. AI is used for assisted routing, knowledge Q&A and optional free chat, and local features work in offline mode.
