  title: Slack Post a Poll Message, Seed Reactions, and Read Tally
  summary: Post a message, seed two reaction options, and read back the reaction tally.
  description: >-
    A lightweight poll pattern built entirely on reactions. The workflow posts a
    prompt message, seeds it with two reaction options for members to vote with,
    and then reads the reactions back so the current tally can be inspected.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
