  title: Slack Announce and Archive a Channel
  summary: Post a final notice to a channel and then archive it.
  description: >-
    A wind down pattern that closes out a channel cleanly. The workflow posts a
    final notice message explaining that the channel is being archived, then
    archives the channel so it is removed from active use while remaining
    searchable. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
