What permissions are required for the User Token?

Your Slack User Token (xoxp-) must have the 'chat:write' scope enabled to allow the skill to delete your messages.

How do I configure the tokens for this skill?

Tokens should be added to your .claude/settings.local.json file under the mcpServers environment variables as SLACK_BOT_TOKEN and SLACK_USER_TOKEN.

Is there a way to undo a message deletion?

No, deletions via the Slack API are permanent. The skill includes a confirmation prompt to ensure you want to proceed before execution.

Can I delete messages sent by other users?

No, you can only delete your own messages if a User Token is configured, or messages sent by the bot itself using a Bot Token.

Collaboration Tools

Deletes Slack messages directly through Claude Code using either user or bot tokens with built-in safety confirmations.

About

The Slack Message Deleter skill empowers developers to manage Slack communication history without leaving their terminal environment. By integrating with Slack's API, it allows for the removal of your own messages using a User Token (xoxp-) or bot-generated messages using a Bot Token (xoxb-). The skill prioritizes safety by performing a token status check and requiring explicit user confirmation—displaying channel IDs and timestamps—before any permanent deletion occurs, making it an essential tool for maintaining clean communication channels and correcting errors quickly.

Key Features

Clear result reporting to verify successful message removal
Precise targeting using Slack Channel IDs and message timestamps
Supports both User Token (own posts) and Bot Token (bot posts) deletion
1 GitHub stars
Mandatory safety confirmation workflow displaying message metadata
Automatic token validation to determine available deletion permissions

Use Cases

Removing sensitive information or accidental posts from Slack channels instantly
Cleaning up automated bot notifications and test messages during development
Managing Slack message history directly from the CLI to maintain focus
