# Resume Agent Run Stream

`POST /agents/{agent_id}/runs/{run_id}/resume`

Resume an SSE stream for an agent run after disconnection.

Sends missed events since `last_event_index`, then continues streaming live events if the run is still active.

**Three reconnection paths:**
1. **Run still active**: Sends catch-up events + continues live streaming
2. **Run completed (in buffer)**: Replays missed buffered events
3. **Run completed (in database)**: Replays events from database

**Client usage:**
Track `event_index` from each SSE event. On reconnection, pass the last received `event_index` as `last_event_index`.

## Path parameters

- `agent_id` string, required

## Response `200`
