≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Slack Bot

Team communication through Slack's API.

When to Use

  • User wants to send or read Slack messages
  • User needs channel monitoring or alerts
  • User wants to post status updates or reports
  • User asks about team conversations

Procedure

  1. Verify Slack token is configured
  2. Identify target channel or user
  3. Perform the messaging operation
  4. Confirm delivery

Operations

  • Send message to channel or DM
  • Read recent messages from a channel
  • React to messages with emoji
  • Create and manage threads
  • Post formatted blocks (rich text, buttons, etc.)
  • Schedule messages for later delivery
  • List channels and members

Message Formatting

Use Slack's Block Kit for rich messages:

  • Text sections with markdown
  • Dividers and headers
  • Button actions
  • Code blocks

Pitfalls

  • Bot must be invited to channels to read/write
  • Rate limits: 1 message per second per channel
  • File uploads require files:write scope
  • Thread replies need the parent message timestamp

Verification

  • Message appears in target channel
  • Reactions are visible on the message
  • Scheduled messages show in Slack's scheduled list
