A field test identified a bug in LangChain where enabling structured output prevented agents from streaming intermediate natural language responses before tool calls. The issue, tracked as LangChain #34818, caused the agent to skip conversational steps like "I'm going to check that now..." before executing a tool. A proposed repair focuses on respecting the boundary between the agent's intermediate conversational turns and the final enforcement of structured output, rather than weakening the structured output feature itself.
