# stream\_emitter

> This is a method of the [**AgentTeam**](../classes/AgentTeam) class in the [**agents**](../modules/agents) module.

Aggregate `StreamEventEmitter` fanning in member agents' events.

Lazily created on first access. On creation it registers a forwarding
callback on each member agent's own `stream_emitter` so per-step
events (tool calls, text/reasoning deltas, retries, errors) surface on a
single team-level emitter, each tagged with the emitting agent's
`agent_id`. This gives a single attach point (e.g. the CLI
`--output stream-json` bridge) parity with single-agent runs.

Zero-overhead when unused: nothing is wired unless this property is
accessed, and forwarding only tags `agent_id` when the source event
did not already carry one.
