Skills (16)

• a2a-agent-card

  Create and configure A2A Agent Cards — the discovery document describing an agent's capabilities, skills, authentication, and endpoint. Use when defining what your agent exposes to other agents.

• a2a-authentication

  Implement A2A authentication — API keys, Bearer tokens, OAuth 2.0, OpenID Connect, and mutual TLS. Use when securing agent-to-agent communication and configuring Agent Card security schemes.

• a2a-client

  Build an A2A client — the agent-side code that discovers other agents, sends tasks, handles responses, and manages multi-turn conversations. Use when implementing the client side that delegates work to A2A agents.

• a2a-dev-patterns

  Apply A2A cross-cutting development patterns — orchestration topologies, idempotency, observability, agent registries, versioning, and production deployment. Use when architecting multi-agent systems or solving cross-cutting concerns.

• a2a-error-handling

  Implement A2A error handling — JSON-RPC errors, A2A-specific error codes, task failure states, retry strategies, and graceful degradation. Use when building robust error handling in A2A agents.

• a2a-framework-integration

  Integrate A2A with agent frameworks — Google ADK, LangGraph, CrewAI, AutoGen, AWS Bedrock AgentCore, and Microsoft Azure AI Foundry. Use when connecting framework-built agents to the A2A protocol for inter-agent communication.

• a2a-jsonrpc-transport

  Implement the A2A JSON-RPC 2.0 transport layer — request/response format, method routing, batch requests, and HTTP details. Use when building custom A2A transport handling or debugging protocol-level issues.

• a2a-mcp-bridge

  Build bridges between A2A and MCP — wrap A2A agents as MCP tools, use MCP tools from A2A agents, and architect hybrid multi-agent systems. Use when integrating A2A agent-to-agent communication with MCP tool access.

• a2a-messages-parts

  Implement A2A messages and parts — TextPart, FilePart, DataPart, message roles, metadata, and content negotiation. Use when building message construction, parsing, or content type handling in A2A agents.

• a2a-multi-turn

  Implement A2A multi-turn conversations — input-required state handling, context preservation, iterative refinement, and human-in-the-loop patterns. Use when building agents that need back-and-forth interaction.

• a2a-push-notifications

  Implement A2A push notifications — callback URL registration, notification delivery, and management methods. Use when building async notification delivery for long-running A2A tasks.

• a2a-server

  Build an A2A server — the agent-side endpoint that receives JSON-RPC requests, processes tasks, manages state, and returns results. Use when implementing the server side of an A2A agent.

• a2a-setup

  Scaffold a new A2A project — install the SDK, create directory structure, configure the Agent Card, and set up a basic server/client. Use when starting a new A2A multi-agent project from scratch.

• a2a-streaming

  Implement A2A SSE streaming — message/stream method, Server-Sent Events, TaskStatusUpdateEvent, TaskArtifactUpdateEvent, and re-subscription. Use when building real-time streaming responses in A2A agents.

• a2a-task-lifecycle

  Implement A2A task lifecycle management — task creation, state transitions, terminal states, history, and artifacts. Use when building task state machines, handling state transitions, or managing task persistence.

• a2a-testing

  Test A2A implementations — unit tests, integration tests, mock agents, protocol conformance, and end-to-end multi-agent testing. Use when building test suites for A2A servers, clients, or multi-agent systems.

Subagents (1)

• a2a-expert

  Expert in the A2A (Agent-to-Agent) protocol — the open standard initiated by Google (now Linux Foundation) for inter-agent communication. Deep conceptual knowledge of Agent Cards, task lifecycle, messages and parts, JSON-RPC transport, streaming, push notifications, authentication, multi-turn conver
