Agent Interoperability Framework

via “framework integration patterns for existing agent platforms”

Agent2Agent (A2A) is an open protocol enabling communication and interoperability between opaque agentic applications.

Unique: Provides documented integration patterns and reference implementations for major frameworks, enabling existing agent ecosystems to adopt A2A incrementally without greenfield rewrites — unlike protocols that require framework-level adoption

vs others: More practical than requiring framework rewrites and more standardized than ad-hoc integration approaches, enabling rapid adoption across existing agent platforms
