Beta Managed Agents Span Outcome Evaluation End Event

• BetaManagedAgentsSpanOutcomeEvaluationEndEvent object

  Emitted when an outcome evaluation cycle completes. Carries the verdict and aggregate token usage. A verdict of needs_revision means another evaluation cycle follows; satisfied, max_iterations_reached, failed, or interrupted are terminal — no further evaluation cycles follow.

  • type: "span.outcome_evaluation_end"

  • id: string

    Unique identifier for this event.

  • explanation: string

    Human-readable explanation of the verdict. For needs_revision, describes which criteria failed and why.

  • iteration: number

    0-indexed revision cycle, matching the corresponding span.outcome_evaluation_start.

    format: int32

  • outcome_evaluation_start_id: string

    The id of the corresponding span.outcome_evaluation_start event.

  • outcome_id: string

    The outc_ ID of the outcome being evaluated.

  • processed_at: string

    A timestamp in RFC 3339 format

    format: date-time

  • result: string

    Evaluation verdict. 'satisfied': criteria met, session goes idle. 'needs_revision': criteria not met, another revision cycle follows. 'max_iterations_reached': evaluation budget exhausted with criteria still unmet — one final acknowledgment turn follows before the session goes idle, but no further evaluation runs. 'failed': grader determined the rubric does not apply to the deliverables. 'interrupted': user sent an interrupt while evaluation was in progress.

  • usage: BetaManagedAgentsSpanModelUsage

    Token usage for a single model request.

    • cache_creation_input_tokens: number

      Tokens used to create prompt cache in this request.

      format: int32

    • cache_read_input_tokens: number

      Tokens read from prompt cache in this request.

      format: int32

    • input_tokens: number

      Input tokens consumed by this request.

      format: int32

    • output_tokens: number

      Output tokens generated by this request.

      format: int32

    • speed: optional "standard" or "fast" or null

      Inference speed mode. fast provides significantly faster output token generation at premium pricing. Not all models support fast; invalid combinations are rejected at create time.

      • "standard"

      • "fast"
