About this skill

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.
