AI Agent Development Study Guide

Learn how to build production-grade AI agents by studying Claude Code's architecture

About This Study Guide

This documentation provides a structured learning path for understanding AI agent development through the Claude Code codebase - a production-grade AI coding assistant that was accidentally exposed through an npm source map leak.

**What makes this unique**: Unlike toy examples or tutorials, this is real production code (~512,000 lines) from Anthropic, showing how they architect autonomous AI agents at scale.

Prerequisites

Before diving in, you should have:

• Strong TypeScript/JavaScript knowledge
• Understanding of async/await and Promises
• Basic familiarity with AI/LLM concepts (prompts, tokens, API calls)
• Terminal/CLI experience
• Git and npm basics

**Optional but helpful**:

• React knowledge (for understanding the UI layer)
• Experience with tool-calling LLMs (Claude, GPT-4)
• Understanding of software architecture patterns
