A2A Protocol Skill

Agent-to-agent communication for task delegation works by using a defined protocol that supports JSON-RPC 2.0 for task creation and SSE for lifecycle streaming. This enables an orchestrator to send tasks to specialized remote agents and monitor their progress.

The best way to discover remote agent capabilities is by using defined discovery endpoints. These endpoints allow your primary agent to query available remote agents, determine their specific skill requirements, and identify suitable targets for task delegation.

Yes, you can use JSON-RPC 2.0 to orchestrate multi-agent collaboration. It serves as the task creation API within the protocol, allowing a primary agent to distribute complex problem-solving workloads across multiple specialized remote agents.

To delegate code execution, your research agent uses the task management API to send a task with specific skill requirements to a remote agent's endpoint. The remote agent then executes the code, such as running pytest tests, and streams lifecycle updates back.

Yes, task delegation supports real-time lifecycle streaming for remote execution through Server-Sent Events (SSE). This mechanism provides continuous updates on the status of delegated tasks as they are processed by the remote agent.

You should not use remote agent delegation for simple, self-contained tasks that do not require specialized capabilities or multi-agent collaboration. It is designed for complex workflows where distributing problem-solving across specialized agents provides a clear advantage.
