Editing Agent-to-Agent Protocol (section)

== Overview ==

A2A addresses the challenge of [[wp:Multi-agent_system|agent interoperability]] in enterprise environments where multiple specialized agents from different vendors need to collaborate. It enables agents to work together regardless of their underlying framework or technology stack, building on concepts from traditional [[wp:Agent_Communications_Language|Agent Communications Languages]].

=== Design principles ===

Google designed A2A around five key principles:

# '''Embrace agentic capabilities''' – Enable natural multi-agent collaboration without limiting agents to simple tools
# '''Build on existing standards''' – Use HTTP, SSE, and JSON-RPC for easy integration
# '''Secure by default''' – Enterprise-grade authentication and authorization
# '''Support for long-running tasks''' – Handle tasks that may take hours or days
# '''Modality agnostic''' – Support text, audio, and video streaming
