Slack Actions

Slack Actions Skill

Overview

The Slack Actions Skill enables Clawdbot to securely interact with Slack channels and direct messages using a Bot OAuth token.

This skill allows agents to:

• Send, edit, and delete messages
• Add and list reactions
• Pin and unpin messages
• Read recent channel history
• Retrieve member information
• List workspace emojis

All actions are executed using the permissions granted to the configured bot account.

Purpose & Capability

This skill enables authenticated Slack operations using a Bot OAuth token supplied through the SLACK_BOT_TOKEN environment variable.

With valid credentials, the skill can:

• Manage messages and reactions
• Maintain pinned references
• Retrieve basic user metadata
• Support lightweight workflow automation

The skill operates strictly within the authorization scope of the configured Slack bot.

Authentication & Configuration

Required Environment Variable

This skill requires a Slack Bot User OAuth token.

Before use, configure:

SLACK_BOT_TOKEN

Example:

export SLACK_BOT_TOKEN="xoxb-xxxxxxxxxxxx-xxxxxxxxxxxx-xxxxxxxxxxxx"

Or in .env format:

SLACK_BOT_TOKEN=xoxb-xxxxxxxxxxxx-xxxxxxxxxxxx-xxxxxxxxxxxx

Token Requirements

The token must include the following OAuth scopes:

• chat:write
• channels:read
• channels:history
• reactions:write
• pins:write
• users:read
• emoji:read

Additional scopes may be required depending on workspace policies.

Credential Storage

• Tokens must be stored only in environment variables
• Tokens must never be hardcoded
• Tokens must never be logged
• Tokens must not be exposed in outputs

If SLACK_BOT_TOKEN is missing, invalid, or revoked, this skill must not execute.

Initial Setup

To configure this skill:

1. Create a Slack App in your workspace
2. Enable Bot Token authentication
3. Assign required OAuth scopes
4. Install the app to the workspace
5. Copy the Bot User OAuth token
6. Store the token in SLACK_BOT_TOKEN
7. Restart the agent

After setup, the skill becomes available for execution.

Credential Constraints

• Only Bot User tokens (xoxb-) are supported
• User tokens (xoxp-) are not permitted
• Tokens must belong to a single workspace
• Cross-workspace tokens are unsupported
• Tokens must be rotated periodically
• Tokens must comply with organizational security policies

Unauthorized credential usage is prohibited.

When to Use This Skill

Activate this skill when the user requests:

• Sending messages to Slack
• Reacting to messages
• Editing or deleting content
• Pinning or unpinning messages
• Reading recent messages
• Looking up users
• Viewing emojis

Example triggers:

“Send this to #engineering.” “React with a checkmark.” “Pin that message.” “Who is U123?”

Required Inputs

Message Targeting

• channelId — Slack channel ID (ex: C1234567890)
• messageId — Slack timestamp (ex: 1712023032.1234)

Reactions

• emoji — Unicode emoji or :name: format

Sending Messages

• to — channel:<id> or user:<id>
• content — Message text

Message context may contain reusable fields such as channel and slack message id.
