summary: "Yuanbao bot overview, features, and configuration" read_when:

• You want to connect a Yuanbao bot
• You are configuring the Yuanbao channel title: Yuanbao

Yuanbao

Tencent Yuanbao is Tencent's AI assistant platform. The OpenKuke channel plugin connects Yuanbao bots to OpenKuke over WebSocket so they can interact with users through direct messages and group chats.

Status: production-ready for bot DMs + group chats. WebSocket is the only supported connection mode.

Quick start

Requires OpenKuke 2026.4.10 or above. Run openkuke --version to check. Upgrade with openkuke update.

1. Add the Yuanbao channel with your credentials

openkuke channels add --channel yuanbao --token "appKey:appSecret"

The --token value uses colon-separated appKey:appSecret format. You can obtain these from the Yuanbao app by creating a robot in your application settings.

2. Restart the gateway to apply the changes

openkuke gateway restart

Interactive setup (alternative)

You can also use the interactive wizard:

openkuke channels login --channel yuanbao

Follow the prompts to enter your App ID and App Secret.

Access control

Direct messages

Configure dmPolicy to control who can DM the bot:

• "pairing" — unknown users receive a pairing code; approve via CLI
• "allowlist" — only users listed in allowFrom can chat
• "open" — allow all users (default)
• "disabled" — disable all DMs

Approve a pairing request:

openkuke pairing list yuanbao
openkuke pairing approve yuanbao <CODE>

Group chats

Mention requirement (channels.yuanbao.requireMention):

• true — require @mention (default)
• false — respond without @mention

Replying to the bot's message in a group chat is treated as an implicit mention.

Configuration examples

Basic setup with open DM policy

{
  channels: {
    yuanbao: {
      appKey: "your_app_key",
      appSecret: "your_app_secret",
      dm: {
        policy: "open",
      },
    },
  },
}

Restrict DMs to specific users

{
  channels: {
    yuanbao: {
      appKey: "your_app_key",
      appSecret: "your_app_secret",
      dm: {
        policy: "allowlist",
        allowFrom: ["user_id_1", "user_id_2"],
      },
    },
  },
}

Disable @mention requirement in groups

{
  channels: {
    yuanbao: {
      requireMention: false,
    },
  },
}

Optimize outbound message delivery

{
  channels: {
    yuanbao: {
      // Send each chunk immediately without buffering
      outboundQueueStrategy: "immediate",
    },
  },
}

Tune merge-text strategy

{
  channels: {
    yuanbao: {
      outboundQueueStrategy: "merge-text",
      minChars: 2800, // buffer until this many chars
      maxChars: 3000, // force split above this limit
      idleMs: 5000, // auto-flush after idle timeout (ms)
    },
  },
}

Common commands

| Command | Description | | ---------- | --------------------------- | | /help | Show available commands | | /status | Show bot status | | /new | Start a new session | | /stop | Stop the current run | | /restart | Restart OpenKuke | | /compact | Compact the session context |

Yuanbao supports native slash-command menus. Commands are synced to the platform automatically when the gateway starts.

Troubleshooting

Bot does not respond in group chats

1. Ensure the bot is added to the group
2. Ensure you @mention the bot (required by default)
3. Check logs: openkuke logs --follow

Bot does not receive messages

1. Ensure the bot is created and approved in the Yuanbao app
2. Ensure appKey and appSecret are correctly configured
3. Ensure the gateway is running: openkuke gateway status
4. Check logs: openkuke logs --follow

Bot sends empty or fallback replies

1. Check if the AI model is returning valid content
2. The default fallback reply is: "暂时无法解答，你可以换个问题问问我哦"
3. Customize it via channels.yuanbao.fallbackReply

App Secret leaked

1. Reset the App Secret in YuanBao APP
2. Update the value in your config
3. Restart the gateway: openkuke gateway restart

Advanced configuration

Multiple accounts

{
  channels: {
    yuanbao: {
      defaultAccount: "main",
      accounts: {
        main: {
          appKey: "key_xxx",
          appSecret: "secret_xxx",
          name: "Primary bot",
        },
        backup: {
          appKey: "key_yyy",
          appSecret: "secret_yyy",
          name: "Backup bot",
          enabled: false,
        },
      },
    },
  },
}

defaultAccount controls which account is used when outbound APIs do not specify an accountId.

Message limits

• maxChars — single message max character count (default: 3000 chars)
• mediaMaxMb — media upload/download limit (default: 20 MB)
• overflowPolicy — behavior when message exceeds limit: "split" (default) or "stop"

Streaming

Yuanbao supports block-level streaming output. When enabled, the bot sends text in chunks as it generates.

{
  channels: {
    yuanbao: {
      disableBlockStreaming: false, // block streaming enabled (default)
    },
  },
}

Set disableBlockStreaming: true to send the complete reply in one message.

Group chat history context

Control how many historical messages are included in the AI context for group chats:

{
  channels: {
    yuanbao: {
      historyLimit: 100, // default: 100, set 0 to disable
    },
  },
}

Reply-to mode

Control how the bot quotes messages when replying in group chats:

{
  channels: {
    yuanbao: {
      replyToMode: "first", // "off" | "first" | "all" (default: "first")
    },
  },
}

| Value | Behavior | | --------- | -------------------------------------------------------- | | "off" | No quote reply | | "first" | Quote only the first reply per inbound message (default) | | "all" | Quote every reply |

Markdown hint injection

By default, the bot injects instructions in the system prompt to prevent the AI model from wrapping the entire reply in markdown code blocks.

{
  channels: {
    yuanbao: {
      markdownHintEnabled: true, // default: true
    },
  },
}

Debug mode

Enable unsanitized log output for specific bot IDs:

{
  channels: {
    yuanbao: {
      debugBotIds: ["bot_user_id_1", "bot_user_id_2"],
    },
  },
}

Multi-agent routing

Use bindings to route Yuanbao DMs or groups to different agents.

{
  agents: {
    list: [
      { id: "main" },
      { id: "agent-a", workspace: "/home/user/agent-a" },
      { id: "agent-b", workspace: "/home/user/agent-b" },
    ],
  },
  bindings: [
    {
      agentId: "agent-a",
      match: {
        channel: "yuanbao",
        peer: { kind: "direct", id: "user_xxx" },
      },
    },
    {
      agentId: "agent-b",
      match: {
        channel: "yuanbao",
        peer: { kind: "group", id: "group_zzz" },
      },
    },
  ],
}

Routing fields:

• match.channel: "yuanbao"
• match.peer.kind: "direct" (DM) or "group" (group chat)
• match.peer.id: user ID or group code
