In my previous post, we explored Prompt Chaining — the simplest way to break a complex task into sequential steps. But real-world systems rarely follow a straight line. Users don’t come with labels on their foreheads telling you what they need. Sometimes they want to book a flight, sometimes they want a factual answer, sometimes they want something you didn’t even anticipate.

That’s where the Routing pattern comes in. And honestly, this is where things start to feel like you’re building something real.

We are witnessing a massive shift in how we interact with Artificial Intelligence. We are moving from simple, reactive chatbots to Agentic Systems—autonomous entities capable of reasoning, planning, and interacting with the world to achieve complex goals.

But how do we actually build these systems? It’s not just about having a powerful LLM; it’s about the architecture around it. It requires structure, design, and a thoughtful approach to how the agent perceives and acts.
