AgentRunEnded

Value parameters

agent

the agent active when the run ended

messages

this turn's messages, from its user message on; empty when blocked, cancelled, timed out or failed. Not included in toJson, which stays a flat summary.

parentRunId

for a delegated child run, the parent run that started it; None for a top-level run

parentThreadId

for a delegated child run, the thread of the parent whose tool call started it; None for a top-level run

provider

the canonical id of the provider of the run's model calls (the first call's, when they used several), when its client reported one; OpenTelemetry's gen_ai.provider.name

runId

this run

span

the run's own span (design 4.58): its context, its parent - a child run's is the task tool call that started it, a continued run's the context it continued - and when the run started

status

completed, suspended, step_limit_reached, blocked:<guardrail>, cancelled, timed_out or failed

threadId

the conversation's thread; backends use it as the session

usage

this run's own token usage and cost, per model: the model calls the run made, never the thread's earlier runs, so a backend can report it per run (as OpenTelemetry's per-operation gen_ai.usage.*) without double counting
