description: Communicate with other agents using the Agent-to-Agent (A2A) protocol.

Overview

This skill allows the agent to act as a client and communicate with other A2A-compatible agents. It handles agent discovery (via agent-card.json), message sending (via JSON-RPC), and result polling.

Capabilities

  • •Agent Discovery: Validates the target agent by fetching its .well-known/agent-card.json.
  • •Send Message: Sends a prompt/query to the target agent to initiate a task.
  • •Poll Results: Monitors the task status and retrieves the final response when complete.

Scripts

  • •scripts/a2a_client.py: The core python script that implements the A2A client logic.

Usage

Run the script scripts/a2a_client.py with the target agent's URL and your query.

Arguments:

  • •--url: The base URL of the A2A endpoint (e.g., http://target-agent.arpa/a2a/).
  • •--query: The text message or query you want to send to the agent.

Example

To ask a search agent about the latest news about the United States:

bash
python3 genius_agent/skills/a2a_client/scripts/a2a_client.py \
  --url http://searxng-agent.arpa/a2a/ \
  --query "Can you search the latest news about the United States?"

Protocol Flow

  1. •Validation: GET {url}/.well-known/agent-card.json
  2. •Send Message: POST {url} with JSON-RPC method message/send
  3. •Poll Status: POST {url} with JSON-RPC method tasks/get until state is completed (or failed).
