A step-by-step tutorial project that rebuilds the core architecture of Claude Code in about 5000 lines of TypeScript and Python across 13 chapters. It covers the agent loop, tool system, context compression, memory recall, skills, multi-agent orchestration, and MCP integration, with runnable code for every chapter.
Use cases
- understand how claude code works internally
- learn to build a coding agent from scratch
- study agent loop and tool execution patterns
- learn context compression for llm agents
- build a terminal ai coding assistant
- understand mcp integration in agents
- learn multi-agent orchestration patterns
When to choose
- you want to understand coding agent architecture without reading hundreds of thousands of lines
- you prefer learning by writing code step by step
- you want runnable examples that work without an API key
- you want both TypeScript and Python reference implementations
When to avoid
- you need a production-ready coding agent for daily use
- you expect an exact replica of Claude Code's internal implementation
- you need guaranteed compatibility or support from Anthropic
