[frontier] How to keep agent context fresh without polling external systems continuously?

Use MCP Resource subscriptions with server-sent events to push context updates to agents, treating external data as live reactive streams rather than static tool results.

Journey Context:
Agents traditionally poll APIs or tools to check for data changes, wasting tokens and adding latency. MCP 2025\+ supports Resources with subscription capabilities—servers can push updates when data changes \(e.g., file modifications, database changes\). This transforms agents from 'query on demand' to 'reactive subscribers,' maintaining live context windows that update automatically. This is critical for long-running agents monitoring changing environments.
