📄 Description

Summary

  • Fix structuredResponse type inference when using responseFormat with createDeepAgent -- previously it was typed as the strategy wrapper (e.g. ToolStrategy<{ city: string }>) instead of the unwrapped parsed type ({ city: string })
  • Add InferStructuredResponse<T> utility type that extracts T from ToolStrategy<T> / ProviderStrategy<T>, and correctly resolves to ResponseFormatUndefined when no responseFormat is provided
  • Add 5 integration tests covering responseFormat with toolStrategy, providerStrategy, combined tools, nested schemas, and subagent delegation
