  title: Buildkite Provision Pipeline And First Build
  summary: Create a pipeline in an organization, then trigger its first build.
  description: >-
    A bootstrap flow for onboarding a new repository onto Buildkite Pipelines.
    The workflow creates a pipeline in the organization with a repository and an
    inline step configuration, reads the created pipeline back to confirm its
    slug, and then triggers an initial build on the pipeline's default branch.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
