  title: X Create a List and Add a Member by Username
  summary: Create a new List, resolve a member handle, and add them to the List.
  description: >-
    Bootstraps a curated X List from scratch. The workflow creates a new List
    for the authenticated user, resolves a member's @username into a numeric
    user id, and adds that user as the first member of the List. The create and
    add steps inline their request bodies so the chain reads and executes
    without opening the underlying OpenAPI description.
