  title: Slack Rename a Channel and Announce the Change
  summary: Rename a channel and post a message announcing the new name.
  description: >-
    A housekeeping pattern that renames a channel and keeps members informed.
    The workflow renames the channel to a new name, captures the updated channel
    record, and posts a message announcing the change so members are not caught
    off guard. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
