VRSEN/agency-swarmv1.3.0Oct 28, 2025by nicko-ai

AI Summary

Feature release focusing on multimodal tool outputs and SDK integration updates.

Key Highlights

  • Support for multimodal tool outputs
  • Bumped Agents SDK to `0.4.1`
  • Runs are now grouped in a single trace
  • `get_response_stream` returns `StreamingRunResponse` immediately

Breaking Changes

  • `Agency.get_response_stream` and `Agent.get_response_stream` now return a `StreamingRunResponse` immediately (synchronous) instead of an awaitable coroutine. Callers must drop the leading `await` and use `await stream.wait_final_result()`.

New Features

  • Multimodal tool outputs
  • SDK integration updates
  • Grouping runs in a single trace

## Streaming API update
- `Agency.get_response_stream` and `Agent.get_response_stream` now return a `StreamingRunResponse` immediately instead of an awaitable coroutine.
- Existing `async for` iteration keeps working, but calling `await` on these methods now raises `TypeError` because they are synchronous.

Updated usage:
```python
stream = agent.get_response_stream(...)
async for event in stream:
...
final_result = await stream.wait_final_result()
```
Drop the leading `await` when obtaining the stream. Callers that previously wrote `await agent.get_response_stream(...)` must adopt the pattern above.
