    Use Cases & Benefits

    • Teaches how to build AI coding agents from scratch using progressive Python tutorials that incrementally add agent capabilities.
    • Provides a minimal, clear, and educational approach to understanding AI agents by implementing core concepts step-by-step in under 1100 lines.
    • Use for learning the fundamentals of AI agent design through hands-on coding of tools, planning, subagents, and skills mechanisms.
    • Use for developing custom AI agents by forking and extending modular agent versions tailored to specific tasks or domains.
    • Use for educators and students seeking a structured tutorial to demystify complex AI agent architectures with practical code examples.

    Learn how modern AI agents work by building one from scratch.

    We created this repository out of admiration for Claude Code - what we believe to be the most capable AI coding agent in the world. Initially, we attempted to reverse-engineer its design through behavioral observation and speculation. The analysis we published was riddled with inaccuracies, unfounded guesses, and technical errors. We deeply apologize to the Claude Code team and anyone who was misled by that content.

    Over the past six months, through building and iterating on real agent systems, our understanding of "what makes a true AI agent" has been fundamentally reshaped. We'd like to share these insights with you. All previous speculative content has been removed and replaced with original educational material.

    Works with Kode CLI, Claude Code, Cursor, and any agent supporting the Agent Skills Spec.

    A progressive tutorial that demystifies AI coding agents like Kode, Claude Code, and Cursor Agent.
