Server-side recording timestamp.

name: String

Tool name.

input: Value

Tool input.

evaluated_permission: Option<AgentEvaluatedPermission>

Permission verdict the platform applied. Ask means the client must reply with a user.tool_confirmation event before the tool runs. None when the tool’s permission policy is allow or the field isn’t reported.

session_thread_id: Option<String>

Set on multi-agent sessions when the request originated in a sub-agent thread. Echo this on the corresponding OutgoingUserEvent::ToolConfirmation or OutgoingUserEvent::CustomToolResult reply so the platform routes it back to the waiting thread. Absent for primary-thread events.

Research-preview: only populated when multi-agent threads are in use.
