Breaking Down Tasks (Task Decomposition) › Breaking Down Tasks (Task Decomposition)

Here's a question you've probably faced in your own life: when someone gives you a big, complicated task, what's the first thing you do?

Most of us don't just dive in randomly. We pause. We think. We break the big task into smaller, more manageable pieces. If someone asks you to "plan a weekend getaway," you don't immediately book a hotel. You first figure out where you might go, then check transportation options, then look at accommodations, and so on. You decompose the large goal into a sequence of concrete steps.

Our AI assistant needs to learn this same skill. Up until now, we've built an agent that can reason, use tools, remember context, and navigate its environment. But when you give it a complex, multi-step request, it needs a way to organize its approach. It needs to plan.

Task decomposition is the foundation of planning. It's the art of taking a big, fuzzy goal and breaking it down into specific, achievable subtasks. In this section, we'll explore why this matters, how agents can do it, and what it looks like in practice.
