Adjusting to A2A Protocol

[sho-takano-dev]

Motivation

I believe the A2A protocol could become a standard for multi-agent applications.

Proposal

To convert a Griptape Agent (structure and tools) into an A2A agent, it would be necessary to add a few variables to the existing agent. However, this does not seem very difficult to implement (as shown in the example code below).

Would this feature be a good addition to the Griptape framework?

I’d be happy to implement this feature if you find it valuable.

from a2a.types import (
    AgentCapabilities,
    AgentCard,
    AgentSkill,
)
from griptape.structures import Agent_A2A
from griptape.tools import CalculatorTool_A2A

# Define A2A Agent 
agent = Agent_A2A(
    input="Calculate the following: {{ args[0] }}", 
    tools=[CalculatorTool_A2A()] # description of tool should be added
    description="A helpful agent that can do simple math calculations" # this should be added
    tags=["math", "calculation"],  # this should be added
    examples=["What is 12345 * 67890?"],  # this should be added
    supported_content_types=["text/markdown", "text/plain"]  # this should be added
)

# main func to describe a2a agent
def main(host, port):
    capabilities = AgentCapabilities(streaming=True, push_notifications=True)
    skill = AgentSkill(
        id = agent.id,
        name = agent.name,
        description = agent.description,
        tags = agent.tags,
        examples= agent.examples,
    )
    agent_card = AgentCard(
        name = agent.name,
        description= agent.description,
        url=f'http://{host}:{port}/',
        version='1.0.0',
        default_input_modes= agent.supported_content_types,
        default_output_modes= agent.supported_content_types,
        capabilities=AgentCapabilities(agent.stream=True, push_notifications=False),
        skills=[skill],
    )

Hey @sho-takano-dev thanks for trying out Griptape! I think we'd like to keep Griptape (mostly) protocol agnostic at this stage, but this is a really interesting idea. Would you mind creating a griptape extension for now and maybe we could upstream in the future?

Thank you so much for your reply, I understand the situation now!
It makes sense to keep Griptape protocol agnostic at this stage.
I'll go ahead and try implementing this as an griptape extension as you suggested.

Fantastic, please let us know if you do make one! We'd love to try it out.

I implemented the sample as written in the new discussuion thread, I’d be happy if you could just take a quick look.
