  title: Slack Look Up a User and Send a Personalized Greeting
  summary: Fetch a user's profile, open a DM, and post a personalized greeting.
  description: >-
    A personalization pattern that greets a known user by their profile name.
    The workflow fetches the user's info by ID, opens a direct message channel
    with them, and posts a greeting that can be personalized from the returned
    profile. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
