Getting Started with Agentic AI

An agent is a program that pursues a goal by taking actions in a loop: it observes, decides, acts, and repeats until the goal is met. That loop is the difference between a chatbot that answers a question and an agent that gets something done.

The core loop

1. Perceive — read the current state (a prompt, a tool result, a file).
2. Decide — choose the next action.
3. Act — call a tool, write a file, ask a question.
4. Repeat until done.

A tiny example

while (!goal.reached()) {
  const obs = perceive();
  const action = model.decide(obs);
  execute(action);
}

Start small: one tool, one goal, one loop. Complexity is earned, not assumed.
