Frameworks for building agents &ndash; LangChain, CrewAI, AutoGen, Semantic Kernel, Vertex AI Agent Builder &ndash; are multiplying rapidly, each with its own internal communication patterns, data formats, and capability advertising mechanisms. This fragmentation creates a fundamental problem: agents built with different frameworks cannot talk to each other.</p> <p><strong>A2A</strong> (Agent-to-Agent), an open protocol initially developed by Google and contributed to the Linux Foundation, aims to solve this interoperability crisis. It defines a standard communication protocol that any agent can implement, regardless of the underlying framework, allowing agents built with different tools to discover each other, negotiate tasks, share information, and collaborate on complex workflows.</p>
