What you get with this Offer
I will implement A2A-compliant agent cards for your AI agents — defining the capability schema, skill descriptions, authentication requirements, and endpoint specifications that allow other A2A-compatible agents to discover and invoke your agents without prior knowledge of their implementation. Agent cards are the A2A protocol's capability discovery mechanism — a well-designed agent card that accurately and completely describes an agent's capabilities, input requirements, and output format enables reliable automated capability matching by calling agents, while an ambiguous or incomplete card produces failed invocations and fallback to human coordination.
The implementation covers agent card JSON schema design for each agent, capability and skill description writing optimised for automated matching, authentication scheme declaration, endpoint specification, agent card hosting at the standard discovery URL, and validation against the A2A specification.
