  title: Runloop Create Scenario and Run It
  summary: Define a repeatable AI coding evaluation scenario, start a run of it, poll until it is scored, then complete the run.
  description: >-
    Scenarios are repeatable AI coding evaluations that pair a starting
    environment with a scoring contract. This workflow creates a scenario with a
    problem statement and a bash script scorer, starts a scenario run on a fresh
    devbox, polls the run until it reaches the scored state (looping while it is
    running or scoring, and ending the flow if it fails, times out, or is
    canceled), then completes the run to release the underlying devbox. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
