# Technical Architecture & Design

> Understanding how the tools work helps you use them better—and debug them when they don't.

This category explores the technical foundations of AI-assisted development tools. From how Claude Code processes your requests, to how the Model Context Protocol enables tool integration, to why sometimes bash is all you need.
