LangGraph with Tool Calling using Claude 3.5 Sonnet

[nacartwright]

I'm building a simple LangGraph with tool calling with the ChatBedrockConverse API. I'm also doing streaming as the application I'm integrating with requires it. The issue I'm having is that the LLM responds with an observation prior to calling the tool and starting to answer the question. For example:

"To get the latest weather information for San Francisco, I'll use the weather_tool. Let me fetch that information for you."

Is there any clever prompting that I can do to identify that as an observation?
