What problem does it solve? It lets an AI agent interact with Yuanbao (元宝) group chats by @mentioning users, sending private messages, and looking up group or member information without manual steps. ## Core Features & Use Cases - @Mention Users: Look up the exact nickname with yb_query_group_members and include @nickname in the reply so the gateway delivers a real mention notification. - Send Direct Messages: Use yb_send_dm to privately message a user by name or user_id, with optional media attachments such as images or documents. - Query Group Data: Retrieve group name, owner, and member count with yb_query_group_info, or list all members and bots. - Use Case: A user says "帮我艾特元宝" in a group chat; the agent finds the exact nickname and replies with a working @mention automatically. ## Quick Start Ask the agent to @mention a specific user or send a private message to someone in the current Yuanbao group.
