A2A Protocol Documentation
The Agent2Agent (A2A) Protocol is an open standard for seamless communication and collaboration between AI agents. It provides a common language for agents built with diverse frameworks (LangGraph, CrewAI, Semantic Kernel, ADK, etc.) enabling interoperability across organizational and platform boundaries. Originally developed by Google and donated to the Linux Foundation.

When to use
Use this skill when the user asks about:
- Implementing A2A protocol in an agent (client or server side)
- Agent-to-agent communication and interoperability
- Task management: creating, streaming, and completing tasks
- Agent Card format and agent discovery
- Streaming responses and asynchronous/push-notification patterns
- Enterprise deployment: authentication, security, multi-tenancy
- Protocol extensions and custom transport bindings
- How A2A relates to or works alongside MCP
- Python SDK usage or the step-by-step Python tutorial
