Slack Actions
Overview
Use the message tool with these actions to control Slack: send, react, reactions, read, edit, delete, download-file, pin, unpin, list-pins, member-info, emoji-list. The tool uses the bot token configured for OpenClaw.
Inputs to collect
channelId(e.g.C123) andmessageId(Slack message timestamp, e.g.1712023032.1234).- For reactions, an
emoji(Unicode or:name:). - For message sends, a
totarget (channel:<id>likeC123or user mention<@U123>).
Message context lines include slack message id and channel fields you can reuse directly.

List custom emojis
/message
action: emoji-listTips & Gotchas
- Mention format: Use
<@U...>instead of@Nameto ensure Slack parses the mention correctly. - Member lookup: If you don't know a user's ID, check recent message context or project board assignee fields. You can also use
member-infoonce you have any guessable ID. - DM policy: Direct messages require
im:writescope and may need explicit pairing if your channel config is restrictive. - Socket Mode vs Bot API: OpenClaw uses Socket Mode for real-time events; all write operations go through bot token scopes.
Ideas to try
- React with ✅ to mark completed tasks.
- Pin key decisions or weekly status updates.
- Introduce yourself using
<@UserID>to trigger notifications. - Monitor channel activity with periodic
readcalls.
