Hello World Agent in AI Agents

Your first agent! A minimal agent that perceives a simple input, reasons about it, and produces output. This foundational exercise shows the perception-reasoning-action loop in its simplest form.

In this exercise, the "environment" is user input, "sensors" are input() functions, "reasoning" is simple if-else logic, and "actuators" are print() functions. Real agents are more complex, but the structure remains the same.

Starting simple builds intuition. Before building multi-agent systems or autonomous systems, understand the basics: How do I perceive? How do I reason? How do I act?
