  title: Buildkite Build Failure Triage
  summary: Inspect a finished build, then pull its annotations and artifacts for triage.
  description: >-
    A diagnostic flow for understanding why a build failed. The workflow fetches
    a build by number, and when it has reached a terminal state it gathers the
    annotations rendered by the build for human-readable failure context and
    lists the artifacts so logs and reports can be retrieved. This gives an
    on-call engineer or an automated triage bot a single pass over the most
    useful failure signals. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
