slack-skill_skill

Overview

This skill lets the agent read, search, and send Slack messages across one or more workspaces. It supports channels, private groups, DMs, threads, and returns JSON-formatted results for easy parsing. Multi-workspace configuration and an optional real-time bridge mode are supported.

How this skill works

The skill uses a Slack bot token to list channels and users, read channel or DM history, search messages, read threads, and add/remove emoji reactions. Sending messages or replying in threads is supported but requires an explicit user confirmation step before the message is dispatched. An optional Socket Mode bridge enables real-time listening and auto-response flows with emoji status feedback.

When to use it

• When you want to read recent messages in a channel or DM
• When you need to search Slack for a specific conversation or keyword
• When you want to send a channel message, DM, or thread reply (with confirmation)
• When you need user details or to list channels and members
• When you want automated responses via the bridge in Socket Mode

Best practices

• Always present full send details (workspace, channel/user, message text, thread context) and ask the user: "Do you want me to send this message?"
• Store bot tokens securely and add the bot to channels before attempting to read or post
• Use --workspace to target the correct workspace in multi-workspace config
• Limit read/search results for faster responses and parse JSON output programmatically
• Use the bridge only when you have Socket Mode app tokens and a clear whitelist for auto-responses

Example use cases

• Check the last 10 messages in #general to catch up on team updates
• Search Slack for "deployment issue" to find past troubleshooting threads
• Prepare a DM to a teammate and request confirmation before sending
• Reply in a thread to acknowledge a discussion or add information
• Run the bridge to auto-respond to tracked threads and show emoji status
