Example of making a model interact with limited fields of a pydantic state?

[intern162]

Imagine the state has three fields:

1. Messages
2. field1
3. field2
   First, the data goes to agent1, which is responsible for modifying field1 and adding to the messages. Then, it proceeds to agent2, which edits field2 before the process ends.

Could you provide an example of how to achieve this using a custom React agent? I'm finding it confusing. Additionally, the tool nodes for each agent are different.

I'm having trouble constructing a node framework that retrieves information from an LLM, updating only the specified fields. For instance, one LLM node should use information from an agent to add to messages and update field1, but not field2.

Thank you.
