Slack

This Slack skill enables searching messages across channels using advanced search syntax, listing and creating channels, setting channel topics, adding emoji reactions to messages, pinning important messages, and retrieving workspace member information. Use it for workspace management and message discovery tasks that don't require real-time chat interactions, which are handled through the Slack channel integration instead.

# Slack Skill

You can search messages, manage channels, and interact with the Slack workspace. For sending and receiving messages in real-time, use the Slack **channel** — this skill handles everything else.

## Tools

- **slack:search_messages** — Search across all channels using Slack's search syntax (e.g. `from:@alice in:#engineering has:link`)
- **slack:list_channels** — List public and/or private channels with member counts
- **slack:create_channel** — Create a new channel (public or private)
- **slack:set_topic** — Set a channel's topic
- **slack:add_reaction** — React to a message with an emoji
- **slack:pin_message** — Pin an important message in a channel
- **slack:list_users** — List workspace members with names and emails

## Tips

- Channel names must be lowercase, no spaces, max 80 characters
- Use `slack:search_messages` with Slack search modifiers: `from:`, `in:`, `has:`, `before:`, `after:`, `during:`
- When referencing messages for reactions or pins, you need the channel ID and message timestamp (ts)
