What the skill teaches
A skill from Slack's official plugin with writing guidance for Slack messages that an agent sends, drafts or schedules through the Slack MCP server's message tools. It explains the Markdown dialect those tools accept, how to structure longer messages and announcements, when to reply in a thread rather than the channel, matching tone to the audience, and how scheduling works. It notes that canvases and Block Kit use different formatting and points to them. It is guidance only; sending messages relies on the Slack MCP server connection that the plugin configures.
