A2A Protocol
Defines the Agent2Agent interoperability protocol and SDKs so agents built on different frameworks discover each other, negotiate capabilities, and exchange tasks.
Skills
Agent Discovery
Publishes and reads Agent Cards so a client can find a remote agent and learn what capabilities it offers.
Task Exchange
Sends long-running tasks between agents with a shared lifecycle covering submitted, working, and completed states.
Streaming and Push Updates
Streams incremental task progress over SSE and delivers push notifications for tasks that outlive the connection.
