# Core Concepts & Paradigm Evolution

> Before picking up tools, understand what game you're playing.

This category covers the foundational concepts you need to navigate the AI-assisted development landscape. From understanding what AI agents actually are, to distinguishing between casual "vibe coding" and disciplined "agentic engineering."
