Feishu advanced configuration

Everything under the original Advanced configuration heading: multiple accounts, delivery limits, streaming cards, quota flags, group session scope, workspace tools, ACP sessions, and multi-agent routing.

Advanced configuration

Multiple accounts

{  channels: {    feishu: {      defaultAccount: "main",      accounts: {        main: {          appId: "cli_xxx",          appSecret: "xxx",          name: "Primary bot",          tts: {            providers: {              openai: { voice: "shimmer" },            },          },        },        backup: {          appId: "cli_yyy",          appSecret: "yyy",          name: "Backup bot",          enabled: false,        },      },    },  },}

defaultAccount controls which account is used when outbound APIs do not specify an accountId. Account entries inherit top-level settings; most top-level keys can be overridden per account. accounts.<id>.tts uses the same shape as tts and deep-merges over global TTS config, so multi-bot Feishu setups can keep shared provider credentials globally while overriding only voice, model, persona, or auto mode per account.

Message limits

• textChunkLimit - outbound text chunk size (default: 4000 chars)
• streaming.chunkMode - "length" (default) splits at the limit; "newline" prefers newline boundaries
• mediaMaxMb - media upload/download limit (default: 30 MB)

Ordinary Markdown cards and rich-text posts are also split to fit Feishu's 30 KB serialized message limit. Headers, notes, mentions, JSON escaping, and UTF-8 text count toward that limit, so chunks may be shorter than textChunkLimit. Long media captions are sent as text/card chunks before the attachment.

Streaming

Feishu/Lark supports streaming replies via interactive cards (Card Kit streaming API). When enabled, the bot updates the card in real time as it generates text.

If Card Kit rejects the completed answer after accepting a streaming preview, OpenClaw sends the complete answer as a separate static reply instead of leaving only the preview.

{  channels: {    feishu: {      streaming: {        mode: "partial", // streaming card output (default: "partial")        block: { enabled: true }, // opt into completed-block streaming      },    },  },}

Set streaming.mode: "off" to send the completed reply without streaming updates; long replies still split at the message limits above. renderMode: "raw" (plain text instead of cards) also disables streaming cards. streaming.block.enabled is off by default; enable it only when you want completed assistant blocks flushed before the final reply. Legacy boolean streaming and the flat blockStreaming / blockStreamingCoalesce / chunkMode keys migrate to this nested shape via openclaw doctor --fix.

Replies with controls use native cards for command buttons and HTTP(S) links, including when streaming is off. The card carries the reply text; attachments remain separate messages. Unsupported controls and cards that exceed Feishu's size limits keep their full labels in a readable fallback. That fallback remains a separate message when a later reply streams. A final controls reply replaces an active streaming preview without sending the preview text again; error controls after a completed answer remain separate. If Feishu cannot delete or clear a replaced preview, delivery reports a failure and retains the original message receipt.

Quota optimization

Reduce the number of Feishu/Lark API calls with two optional flags:

• typingIndicator (default true): set false to skip typing reaction calls
• resolveSenderNames (default true): set false to skip sender profile lookups

{  channels: {    feishu: {      typingIndicator: false,      resolveSenderNames: false,    },  },}

Group session scope and topic threads

channels.feishu.groupSessionScope (top-level, per account, or per group) controls how group messages map to agent sessions:

For the topic scopes, native Feishu/Lark topic groups use the event thread_id (omt_*) as the topic session key. If a native topic starter event omits thread_id, OpenClaw hydrates it from Feishu before routing the turn. Normal group replies that OpenClaw turns into threads keep using the reply root message ID (om_*) so the first turn and follow-up turns stay in the same session.

Set replyInThread: "enabled" (top-level or per group) to make bot replies create or continue a Feishu topic thread instead of replying inline. topicSessionMode is the deprecated predecessor of groupSessionScope; prefer groupSessionScope.

Feishu workspace tools

The plugin ships agent tools for Feishu documents, chats, knowledge base, cloud storage, permissions, and Bitable, plus matching skills (feishu-doc, feishu-drive, feishu-perm, feishu-wiki). Tool families are gated by channels.feishu.tools:

Per-account gates live under accounts.<id>.tools.

After a configuration update is applied, new agent turns use the updated tool gates and account selection without restarting the Gateway. Tools already created for an in-progress turn keep their original configuration.

Bitable operations use the application token from a /base/ URL or returned app_token, not the node token in a /wiki/ URL. If application creation succeeds but table metadata is not retrieved, keep the returned app_token and URL. Inspect that existing application rather than creating another one; a missing table_id does not mean creation failed.

feishu_doc creates title-only documents. To add Markdown, pass the returned document_id as doc_token in a separate write action. A create request that includes content fails without creating an empty document.

Grant drive:drive.metadata:readonly for direct feishu_drive info lookups outside the root directory, unless the app already has the full drive:drive scope. Without either scope, info keeps the legacy root-directory lookup available through drive:drive:readonly.

ACP sessions

Feishu/Lark supports ACP for DMs and group thread messages. Feishu/Lark ACP is text-command driven - there are no native slash-command menus, so use /acp ... messages directly in the conversation.

Persistent ACP binding

{  agents: {    entries: {      codex: {        runtime: {          type: "acp",          acp: {            agent: "codex",            backend: "acpx",            mode: "persistent",            cwd: "/workspace/openclaw",          },        },      },    },  },  bindings: [    {      type: "acp",      agentId: "codex",      match: {        channel: "feishu",        accountId: "default",        peer: { kind: "direct", id: "ou_1234567890" },      },    },    {      type: "acp",      agentId: "codex",      match: {        channel: "feishu",        accountId: "default",        peer: { kind: "group", id: "oc_group_chat:topic:om_topic_root" },      },      acp: { label: "codex-feishu-topic" },    },  ],}

Spawn ACP from chat

In a Feishu/Lark DM or thread:

/acp spawn codex --thread here

--thread here works for DMs and Feishu/Lark thread messages. Follow-up messages in the bound conversation route directly to that ACP session.

Multi-agent routing

Use bindings to route Feishu/Lark DMs or groups to different agents.

{  agents: {    ownership: "explicit",    defaults: {      heartbeat: { agentId: "main" },      systemAgent: { agentId: "main" },    },    entries: {      main: { workspace: "~/.openclaw/workspace" },      "agent-a": { workspace: "/home/user/agent-a" },      "agent-b": { workspace: "/home/user/agent-b" },    },  },  bindings: [    {      agentId: "agent-a",      match: {        channel: "feishu",        peer: { kind: "direct", id: "ou_xxx" },      },    },    {      agentId: "agent-b",      match: {        channel: "feishu",        peer: { kind: "group", id: "oc_zzz" },      },    },    { agentId: "main", match: { channel: "feishu", accountId: "*" } },  ],  talk: { agentId: "main" },}

Routing fields:

• match.channel: "feishu"
• match.peer.kind: "direct" (DM) or "group" (group chat)
• match.peer.id: user Open ID (ou_xxx) or group ID (oc_xxx)
