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
```
) and
```
messageId
```
(Slack message timestamp, e.g.
```
1712023032.1234
```
).
For reactions, an
```
emoji
```
(Unicode or
```
:name:
```
).
For message sends, a
```
to
```
target (
```
channel:<id>
```
like
```
C123
```
or user mention
```
<@U123>
```
).

Message context lines include

slack message id

and

channel

fields you can reuse directly.

Common Patterns

Send a message to a channel

/message

channel: slack
to: C123
message: Hello @everyone!

Send a message to a specific user

/message
action: send
channel: slack
to: <@U123>
message: Hi there!

React to a message

/message
action: react
channelId: C123
messageId: 1712023032.1234
emoji: ✅

List reactions on a message

/message
action: reactions
channelId: C123
messageId: 1712023032.1234

Edit a message

/message
action: edit
channelId: C123
messageId: 1712023032.1234
message: Updated text

Delete a message

/message
action: delete
channelId: C123
messageId: 1712023032.1234

Read recent messages from a channel

/message
action: read
channelId: C123
limit: 20

Pin a message

/message
action: pin
channelId: C123
messageId: 1712023032.1234

Unpin a message

/message
action: unpin
channelId: C123
messageId: 1712023032.1234

List pinned messages in a channel

/message
action: list-pins
channelId: C123

Get member info by user ID

/message
action: member-info
userId: U123

Returns: real_name, display_name, email, avatar URLs, timezone, profile status, etc.

List custom emojis

/message
action: emoji-list

Tips & Gotchas

Mention format: Use
```
<@U...>
```
instead of
```
@Name
```
to 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-info
```
once you have any guessable ID.
DM policy: Direct messages require
```
im:write
```
scope 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
```
read
```
calls.
