name: feishu-thread-forward description: | Forward Feishu thread/topic to a user, group, or topic via REST API. Activate when: forwarding a thread/topic to another chat, sharing a topic post to a different group, or any scenario involving Feishu thread-level forwarding (转发话题). The built-in feishu message tool does NOT support thread forwarding — this skill fills that gap.

Feishu Thread Forward

Forward a Feishu thread (话题) to a user, group, or another topic using the Feishu Open API.

When to Use

• User asks to forward/share a thread or topic to another group or user
• You need to cross-post a topic post from one group to another
• The built-in message tool cannot do thread-level forwarding

API

POST https://open.feishu.cn/open-apis/im/v1/threads/{thread_id}/forward?receive_id_type={type}

Parameters

Param	Location	Required	Description
thread_id	path	yes	Thread ID to forward (format: omt_xxxxx)
receive_id_type	query	yes	Target ID type: open_id, chat_id, user_id, union_id, email, thread_id
receive_id	body	yes	Target ID matching the receive_id_type
uuid	query	no	Idempotency key (max 50 chars, dedup within 1 hour)

Headers

Authorization: Bearer {tenant_access_token}
Content-Type: application/json

How to Get thread_id

A message in a topic group has a thread_id field. Retrieve it via:

GET https://open.feishu.cn/open-apis/im/v1/messages/{message_id}

The response data.items[0].thread_id contains the thread ID (e.g., omt_1accc5a75c0f9b93).

Script

Use scripts/forward_thread.py for the complete implementation.

python3 skills/feishu-thread-forward/scripts/forward_thread.py \
  --thread-id omt_xxxxx \
  --receive-id oc_xxxxx \
  --receive-id-type chat_id

Typical Flow

1. Get thread_id — from the message's metadata, or by calling GET message API
2. Call forward API — POST /im/v1/threads/{thread_id}/forward
3. Result — a merge_forward type message appears in the target chat as a clickable topic card

Forward vs Merge Forward vs Message Forward

Method	API	Result
Thread forward (this skill)	POST /threads/{thread_id}/forward	Topic card (clickable, shows thread context) ✅
Merge forward	POST /messages/merge_forward	"群聊会话记录" bundle (expandable message list)
Message forward	POST /messages/{message_id}/forward	Single message copied to target (loses thread context)

Thread forward is what users see when they click "转发话题" in Feishu client.

Prerequisites

• Bot must be in the source group (and can see the thread)
• Bot must be in the target group (or target user must be in bot's availability scope)
• Bot needs im:message or im:message:send_as_bot permission

Credentials

Read from /root/.openclaw/openclaw.json → channels.feishu.appId / channels.feishu.appSecret to obtain tenant_access_token.
