Module 3: The Brain (Logic & Loops)

Sat Jan 31 2026

In Module 1 and 2, we built linear pipelines ($A \to B \to C$). They were robust, but dumb. They couldn’t make decisions or try again if they failed.

In this module, we will introduce Conditional Edges. This is the mechanism that turns a static graph into a dynamic “Agent.”

What you will learn:

1. The Router: How to branch the path based on data ($A \to B$ or $C$).

2. The Loop: How to retry steps until a goal is met (Cyclic Graphs).
