  title: Slack Find User by Email and Direct Message Them
  summary: Look up a user by email, open a direct message channel, and post a message.
  description: >-
    A direct outreach pattern that turns an email address into a one to one
    Slack conversation. The workflow resolves the email to a Slack user ID,
    opens (or reuses) a direct message channel with that user, and posts the
    supplied message into the DM. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
