The Future of AI Agents Might Not Be Bigger Context Windows

So, I keep wondering if we’re building agents around the wrong assumption. most agent architectures assume one agent should do all the thinking. That agent holds the memory, context, reasoning, planning, tool definitions, history, and domain expertise. As capabilities grow, context grows. As context grows, costs increase and reasoning quality degrades. What if the agent didn’t need to know everything? What if the agent’s job was simply to route work to specialists? Imagine every specialist as a callable service with its own: • Model • Context window • Knowledge • Memory • Execution environment Instead of loading expertise into the agent, the agent calls the expertise. The agent becomes a router. The specialists do the thinking. This feels similar to how software evolved from monoliths to microservices. Not sure if this pattern emerge in production agent systems. But I believe heading toward networks of specialized reasoning services seems to be the right path.
