Enables autonomous agent-to-agent commerce flows using the Universal Commerce Protocol (UCP) A2A binding and structured message parts.

This skill empowers Claude to implement and manage fully autonomous commerce transactions between AI agents using the UCP A2A binding. It provides domain-specific expertise for building inter-agent communication flows where a platform agent and a business agent exchange structured DataPart objects, Agent Cards, and secure checkout mandates. By integrating with Google's A2A transport protocol and supporting AP2 mandate flows with SD-JWT credentials, it allows developers to create sophisticated multi-agent architectures that handle everything from discovery to payment completion without direct human intervention.
