Generates and manages A2A discovery documents to define agent capabilities, skills, and authentication for multi-agent systems.

The A2A Agent Card Builder skill enables developers to create and configure standardized discovery documents for autonomous agents, functioning as the 'OpenAPI spec' for agent-to-agent (A2A) communication. It guides the implementation of the identity, capabilities, skills, and security sections required for an agent to be discoverable by other AI agents or registries. This skill is essential for building interoperable agentic commerce solutions, ensuring that agents can accurately advertise their services, validate against official A2A schemas, and maintain secure, authenticated connections across multi-agent workflows.
