# Slack Actions

## Overview

Use `slack` to react, manage pins, send/edit/delete messages, and fetch member info. The tool uses the bot token configured for OpenClaw.

## Inputs to collect

- `channelId` and `messageId` (Slack message timestamp, e.g. `1712023032.1234`).
- For reactions, an `emoji` (Unicode or `:name:`).
- For message sends, a `to` target (`channel:<id>` or `user:<id>`) and `content`.

Message context lines include `slack message id` and `channel` fields you can reuse directly.
