SubagentStatus

The execution status of a subagent.

• "pending" - The subagent has been invoked but hasn't started processing yet. This is the initial state when a tool call is detected but before any streaming events are received from the subgraph.

• "running" - The subagent is actively executing and streaming updates. The subagent transitions to this state when the first update event is received from its namespace.

• "complete" - The subagent has finished execution successfully. A tool message with the result has been received, and the result property contains the final output.

• "error" - The subagent encountered an error during execution. The error property on the SubagentStream contains error details.
