# Protobufs for Agent2Agent (A2A) Protocol [](https://opensource.org/licenses/MIT) <!-- Choose your license and update badge --> []() <!-- Optional: Badge indicating community effort --> ## Overview This repository provides Protobuf (`.proto`) definitions derived from the official [Agent2Agent (A2A)](https://github.com/google/A2A/tree/main) protocol. The official A2A protocol specifications are defined using JSON Schema. This project aims to offer an alternative representation using Protobufs for potential benefits in performance, type safety, and cross-language code generation. This is not an official A2A Protocol project. Definitions are not guaranteed to be accurate, complete or up-to-date and may change based on feedback and updates to the official protocol. For official definitions and documentation, please refer to the following: * Website: https://google.github.io/A2A * GitHub repository: https://github.com/google/A2A * Blog: https://developers.googleblog.com/en/a2a-a-new-era-of-agent-interoperability/ ## Purpose The primary goals of this project are: 1. **Provide A2A Protobuf Definitions:** Offer Protobuf definitions that correspond to the official A2A Protocol specification. 2. **Facilitate Integration:** Enable developers who prefer or require Protobufs to interact with / build systems using the A2A protocol. 3. **Collaboration:** Create a space for discussion, feedback, and improvement of the use of Protobufs for developing A2A-compliant systems. ## Why Protobuf for A2A? Using Protobufs offers several potential advantages: * **Efficiency:** Protobuf serialization is often more compact and performant than JSON. * **Type Safety:** Protobuf definitions provide strong typing, which can be checked at compile time in many languages. * **Code Generation:** Protobuf compilers can automatically generate data access classes in various programming languages (Java, Python, C++, Go, C#, etc.). ## Project Structure ``` a2a-protobuf/ ├── a2a/ │ └── v1/ │ └── service.proto # A2A Protocol Protobuf definitions ├── LICENSE # Project license └── README.md # This file ``` ## Contributing Contributions and suggestions are welcome!
