🧠 TL;DR

Most people think AI coding tools are “magic.”

They’re not.

They’re well-designed systems built on:

• simple loops
• structured tool usage
• clear separation of responsibilities

⚙️ 1. Core Idea: The Agent Loop

At the heart of the system is a simple repeatable loop:

Task → Plan → Tool → Result → Repeat

What this means:

• The AI doesn’t “solve everything at once”
• It iterates step-by-step
• Each step is small, controlled, and testable

Why it matters:

• Easier to debug
• More reliable than long prompts
• Scales better in production
