A2A Communication

5 Steps

1. 1

   Define Message Structure: Create a data structure for A2A messages. Include fields for sender ID, receiver ID, message type, payload (as a JSON string), and contract ID.

2. 2

   Implement Message Sending: Implement a function to send A2A messages. This function should serialize the message to JSON and transmit it over a communication channel (e.g., HTTP, message queue).

3. 3

   Implement Message Receiving: Implement a function to receive A2A messages. This function should listen on a communication channel, deserialize the JSON message, and process it based on the message type and contract ID.

4. 4

   Define Contract Negotiation: Implement a simple contract negotiation protocol. Agents exchange 'propose', 'accept', and 'reject' messages to agree on a contract (e.g., task parameters, data format).

5. 5

   Implement Capability Discovery: Implement a mechanism for agents to advertise and discover their capabilities. This could involve a central registry or a broadcast-based discovery protocol.
