  title: X List Who Reposted a Handle's Latest Post
  summary: Resolve a handle, get their latest post, then list who reposted it.
  description: >-
    Produces a repost audit for an X account. The workflow resolves a username
    to an id, retrieves that user's single most recent post, and then lists the
    users who reposted that post. Each step inlines its field selections so the
    chain reads and executes without opening the underlying OpenAPI description.
