pass Valid AgentCard 10/10

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload.

No protocolVersion in card.

            How to earn +10 points

            How to earn +4 points
