The key of the currently-active element instance for this agent instance. Used for ownership/equality validation against the stored agent instance and, when the supplied key differs from the previous association (re-entry of an ad-hoc sub-process or AI Agent task), appended to elementInstanceKeys with the reverse link updated on the supplied element instance. Only one element instance may hold this write claim at a time: any update from a different element instance is rejected while the current writer's job is still active.
OptionalhistoryA batch of history items to append to the agent instance's conversation history, in request order. Each created item is echoed back in the response's createdHistory, positionally correlated.
The key of the job activation during which this update is being made. An update must always be attributed to the active job that produced it.
Opaque lease token received from the job activation response. Disambiguates this activation from any other activation of the same job: if the job is later retried, history items submitted under a superseded lease are discarded rather than committed.
OptionalstatusThe new status of the agent instance.
Request to update the mutable state of an agent instance.
