Overview

Agent2Agent (A2A) is an open protocol enabling communication and interoperability between opaque agentic applications.

Key Features

Standardized Communication: Defines standard message formats and protocols for AI agents to communicate and coordinate tasks.
Interoperability: Enables agents built on different frameworks or by different organizations to interact seamlessly.
Extensibility: Designed to allow developers to define custom capabilities and schemas for their specific use cases while maintaining compatibility.
Open Specification: Maintained as an open-source standard to foster collaboration in the multi-agent ecosystem.

Use Cases

Multi-Agent Systems: Ideal for scenarios where multiple specialized AI agents need to collaborate to solve complex problems, such as a research agent handing off data to a writing agent, or a coding agent communicating with a testing agent.

Getting Started

Review the protocol specification in the GitHub repository to understand the core concepts and message schemas. Developers can implement the protocol in their agentic applications to enable A2A communication.

Recent Updates

Release v1.0.1 includes bug fixes for the HTTP binding to prefer application/a2a+json, transcoding-related changes, and TaskStatus value updates.
