[frontier] How do I stream state changes between agents without polling?

Use MCP Resources with server-sent event subscriptions to push state updates, treating agents as reactive data sources rather than RPC endpoints.

Journey Context:
Developers use MCP only for tool calling \(request-response\) but miss that Resources support subscriptions for streaming. This enables reactive multi-agent topologies where downstream agents update when dependencies change, eliminating polling overhead and stale state.
