Detailed Changes

ToolNode (langgraph prebuilt module)

• Replaced str_output function with an improved msg_content_output function that can return multimodal content
• The function now detects and preserves recognized content blocks (image, image_url, text, json) rather than converting everything to strings
• Updated tool execution methods to support structured message content while maintaining backward compatibility
• Tools can now return rich content that will be properly passed to the LLM, enabling multimodal interactions
