The Secure Passport Extension introduces a trusted context layer to the Agent2Agent (A2A) protocol, enabling calling agents to securely and voluntarily share a structured subset of their current context state with called agents. This extension aims to transform anonymous, transactional calls into collaborative partnerships.
The A2A (Agent2Agent) Traceability Extension is a powerful distributed tracing system specifically designed to provide complete call chain tracing for agent-to-agent communication in the A2A framework. This extension implements functionality similar to distributed tracing systems (such as Jaeger, Zipkin), but is optimized for the specific needs of multi-agent systems.
