name	message-push
description	Send proactive messages to IM groups or individual users via the gateway Send API. Use when the user says to send, post, notify, forward, or tell someone a message on Feishu, Slack, Telegram, Discord, DingTalk, or WeCom.

Message Push

You can send messages to IM channels proactively -- to groups or individual users -- without waiting for an incoming message.

Recognizing Push Intent

Note: if the user asks you to send a FILE or IMAGE (e.g. a generated document, chart, photo), do NOT use this skill — instead save to temp_file/ and emit [SEND_IMAGE: ...] / [SEND_FILE: ...] markers (see the im-adapter skill). This skill only sends TEXT messages.

Watch for phrases like:

• "send this to the ops group"
• "tell Alice in DM that..."
• "post this summary to #general"
• "notify the team on Feishu"
• "forward this to chat oc_xxx"

Sending Workflow

Follow these steps when the user requests a message push:

1. Identify the target -- determine the channel name and chatId from the user's request
2. Discover available channels -- call GET /api/channels to confirm the channel exists and supports sending
3. Compose the message -- draft the text content, following im-adapter formatting guidelines
4. Confirm with the user -- if this is the first time sending to this chat, show the draft and ask for approval
5. Send the message -- call POST /api/send with the channel, chatId, and text
6. Report the result -- tell the user whether the send succeeded or failed

Send API

curl -X POST http://localhost:$PORT/api/send \
  -H "Content-Type: application/json" \
  -d '{
    "channel": "feishu",
    "chatId": "oc_xxxx",
    "text": "Hello from the bot!"
  }'

Request Fields

Field	Type	Required	Description
channel	string	yes	Channel name: feishu, dingtalk, wecom, slack, telegram, discord
chatId	string	yes	Chat/group/conversation ID on the target platform
text	string	yes	Message content (Markdown supported)

Response

• 200 { "ok": true } -- message sent successfully
• 404 -- channel not found (check available channels)
• 501 -- channel does not support proactive send
• 503 -- no channel adapters available

Error Handling

If the send fails, check the HTTP status code:

• For 404, run GET /api/channels and inform the user which channels are actually available
• For 501, explain that the target channel adapter does not support proactive sending
• For 503, inform the user that no IM adapters are currently running

Discovering Available Channels

Before sending, check which channels are available:

curl http://localhost:$PORT/api/channels

Returns:

{
  "channels": [
    { "name": "feishu", "canSend": true },
    { "name": "slack", "canSend": true }
  ]
}

Finding Chat IDs

Chat IDs are platform-specific. Common ways to find them:

Channel	How to find chatId
Feishu	Group settings > Group ID (starts with oc_)
Slack	Channel ID from URL (C prefix) or user ID (U prefix) for DMs
Telegram	Chat ID from message events (negative for groups)
Discord	Channel ID from URL or developer mode
DingTalk	Conversation ID from webhook or API
WeCom	Chat ID from API

If the user references a group by name rather than ID, check group memory files in memory/groups/ -- the group key format is {channel}-{chatId}.

Guidelines

• Always confirm with the user before sending to a new chat for the first time
• For DMs, make sure the recipient has interacted with the bot before (most platforms require this)
• Keep messages concise -- follow the im-adapter formatting guidelines
• If the user says "send to the group" without specifying which one, check the current conversation context or ask
