a2a-protocol

Add a specific feature to an existing A2A Protocol project. Features include agent, client, discovery, streaming, production, test.

**Project Name:** `$0`

Use this agent to build A2A-compatible agents with agent cards, skills, and executor implementation

Use this agent to create A2A clients to communicate with and delegate tasks to A2A agents

Use this agent to setup agent discovery mechanisms for finding and connecting to A2A agents dynamically

Use this agent to add enterprise features, extensions, and production-ready configurations for A2A agents

Use this agent to setup A2A Protocol SDK in Python, TypeScript, Java, C#, or Go projects with proper dependencies and configuration

Use this agent to implement streaming responses and asynchronous operations for A2A agents following the Agent-to-Agent protocol specifications

Use this agent to test and validate A2A implementations for protocol compliance and functionality

Agent-to-Agent (A2A) executor implementation patterns for task handling, execution management, and agent coordination. Use when building A2A executors, implementing task handlers, creating agent execution flows, or when user mentions A2A protocol, task execution, agent executors, task handlers, or agent coordination.

Integration patterns for combining Agent-to-Agent (A2A) Protocol with Model Context Protocol (MCP) for hybrid agent communication. Use when building systems that need both agent-to-agent communication and agent-to-tool integration, implementing composite architectures, or when user mentions A2A+MCP integration, hybrid protocols, or multi-agent tool access.

SDK installation and setup patterns for Agent-to-Agent Protocol across Python, TypeScript, Java, C#, and Go. Use when implementing A2A protocol, setting up SDKs, configuring authentication, or when user mentions SDK installation, language-specific setup, or A2A integration.

Agent-to-Agent (A2A) server configuration patterns for HTTP, STDIO, SSE, and WebSocket transports. Use when building A2A servers, configuring MCP transports, setting up server endpoints, or when user mentions A2A configuration, server transport, MCP server setup, or agent communication protocols.

A2A agent card JSON templates with schema validation and examples for different agent types. Use when creating agent cards, implementing A2A protocol discovery, setting up agent metadata, configuring authentication schemes, defining agent capabilities, or when user mentions agent card, agent discovery, A2A metadata, service endpoint configuration, or agent authentication setup.
