This example shows how to use direct messaging to implement
|
|
a simple interaction between an inner and an outer agent.
|
|
1. The outer agent receives a message, sends a message to the inner agent.
|
|
2. The inner agent receives the message, processes it, and sends a response to the outer agent.
|
|
3. The outer agent receives the response and processes it, and returns the final response.
