[frontier] Multi-agent systems require all agents to be on the same framework or platform

Use Google's Agent-to-Agent \(A2A\) protocol to enable agents built on different frameworks to discover each other via Agent Cards and communicate through a standardized JSON-RPC over HTTP interface. Treat agents as opaque services defined by their capabilities, not their implementation.

Journey Context:
The multi-agent landscape is fragmented: LangGraph, CrewAI, AutoGen, and custom agents all have incompatible orchestration models. A2A solves this by defining Agent Cards \(JSON metadata describing capabilities, auth, and endpoints\) and a standard task-based messaging protocol. The key insight is treating agents as opaque services — you don't need to know their internals, just their card. This is the same decoupling that MCP brought to tool interfaces, but at the agent-to-agent level. Tradeoff: A2A adds HTTP overhead vs. in-process communication, and the spec is early and may evolve. But for production systems spanning organizational or framework boundaries, this is the direction. Teams that hard-code framework-specific orchestration now will face painful rewrites.
