WithAgentCard(a2a.AgentCard{ Name: "Example Agent", URL: "https://example.com/agent", Version: "1.0.0", }). WithClient("example-client"). AddMessage( a2a.NewMessageBuilder("user"). AddTextPart("Hello, agent!"). Build(), ). Build() fmt.Printf("Task ID: %s\n", task.ID) fmt.Printf("Task State: %s\n", task.State) } ``` ## Features - Full implementation of the A2A protocol in Go - Builder pattern for creating tasks, messages, and artifacts - OpenTelemetry integration for tracing and metrics - High-performance JSON serialization using Bytedance's Sonic ## License This project is licensed under the Apache 2.0 License - see the [LICENSE](./LICENSE) file for details.
