A2A Consuming Agent Example

This example demonstrates how an ADK agent can consume a remote A2A agent in Go. It sets up a "Root Agent" that delegates tasks to a local "Roll Agent" and a remote "Prime Agent".

Prerequisites

Before running this example, you need to have the A2A serving example running. Follow the instructions in cmd/a2a_basic/remote_a2a/check_prime_agent/README.md to start the serving agent on port 8001.

Files

• main.go: This file contains the implementation of the local Roll Agent, the remote Prime Agent, and the orchestrating Root Agent.

How to Run

1. Ensure the A2A serving example is running (from cmd/a2a_basic/remote_a2a/check_prime_agent).

2. Run this consuming example:

   go run main.go
   

Expected Output

When you run this example, you should see output similar to this:

--- Example Interaction ---
User: Roll a 6-sided die and check if it's prime
Bot calls tool: roll_dice with args: map[sides:6]
Bot calls tool: prime_checking with args: map[nums:[<roll_result>]]
Bot: I can roll dice or check prime numbers. What would you like?

Note: The mock LLM in this example is very basic and will not actually execute the tools or provide a coherent response for combined operations. It's designed to demonstrate the delegation mechanism. For a real-world scenario, you would integrate with an actual LLM.
