About Learn Claude Code

Learn Claude Code is a minimal agent harness implementation that recreates the core loop of Claude Code from zero. Built primarily in Python and Bash, it demonstrates the fundamental architecture of coding agents: tool registration, conversation loops, model routing, and skill execution. With 66K+ GitHub stars, it serves as the most popular educational resource for developers who want to understand agent internals rather than just use them as black boxes.

Key Features

• Minimal agent loop implementation showing core harness patterns: tool use, conversation state, model routing
• Built from scratch in Python and Bash with no heavy framework dependencies
• Educational code structure with inline commentary explaining each architectural decision
• Demonstrates skill registration and execution patterns compatible with major agent frameworks
• 66K+ GitHub stars as the top educational agent harness resource
