+## Overview
+
+A 20-post deep-dive into the architecture of Claude Code (v2.1.88), Anthropic's AI coding agent — 512K lines of TypeScript, approximately 40 tools behind a three-tier permission system, and ML classifiers that gate every shell command. Topics span the agent loop, context engineering, prompt assembly, tool system, safety sandbox, multi-agent orchestration, MCP, skills, plugins, and more.
