Implements and manages A2A protocol message structures, including multi-modal parts, roles, and content negotiation for agent-to-agent communication.

The A2A Messages and Parts skill provides a comprehensive framework for building robust communication channels between agents within the A2A protocol ecosystem. It streamlines the creation and parsing of multi-modal message types—specifically TextPart, FilePart, and DataPart—while ensuring strict adherence to roles, metadata conventions, and content negotiation rules. This is particularly useful for developers building complex agentic commerce workflows where agents must exchange structured data, files, and natural language instructions reliably and in a format-agnostic manner.
