[frontier] Multi-agent systems couple agents to a single framework and fail at cross-team delegation

Adopt an agent-to-agent protocol like A2A for cross-framework task delegation: agents advertise capabilities via Agent Cards, exchange Tasks with Parts, and stream Updates so heterogeneous agents from different teams can collaborate without shared memory.

Journey Context:
The naive pattern is a central orchestrator with direct SDK calls to every agent, which collapses when teams use different stacks. Peer-to-peer agent protocols move the boundary from 'one framework owns all' to 'standardized message passing over HTTP/SSE.' The tradeoff is latency and schema negotiation; the win is composability and team autonomy. Do not use this for intra-agent tool calls where MCP is the better fit.
