📄 Description

Summary

  • Add responseFormat support to subagents, allowing structured output schemas (Zod, toolStrategy, providerStrategy, etc.) to be passed through to createAgent
  • When a subagent produces a structuredResponse, JSON-serialize it as the ToolMessage content instead of extracting the last message text, giving the parent agent predictable, parseable data
  • Add tests for both the structured response path and the fallback to last-message extraction
