Build Your Own Claude Code

Source: https://www.codewithantonio.com/cohorts/build-your-own-claude-code-2026-05

Master a New Development Format — create your own AI tool for programming and learn to work with code as engineers of the future do. Not through step-by-step instructions, but by managing an AI agent as a full-fledged developer.

Why This Approach Matters

Traditional programming learning is based on linear tutorials: you follow steps, manually write each line, and get a predictable result. This is helpful at the start, but it poorly reflects the modern development process.

Today’s key skill is the ability to formulate tasks and make engineering decisions, not manually writing each function. You set the direction, and the AI implements the logic, modifies the project, and suggests solution options. Essentially, explanation becomes code.

What You Will Create in the Course

In 6 days, you will develop a complete CLI tool from scratch at the level of Claude Code — not an educational demo but a real system that can be expanded for your own projects.

• Understand how AI agents work “under the hood”
• Learn to manage code modification and analysis through an agent
• Master the architecture of agentic systems
• Build a working product according to industry principles

How the Learning Takes Place

Each day yields a separate functional result. You do not repeat someone else’s decisions but design and make engineering decisions independently, using AI as part of your team.

Learning Structure

• Day 1: First working prototype of CLI
• Day 2: Connecting the AI agent and basic code editing operations
• Day 3: Project analysis and file structure navigation
• Day 4: Building command architectures and handlers
• Day 5: Implementing complex development scenarios
• Day 6: Optimization, expansion, and preparation for real tasks

What Result You Will Achieve

You will create your own coding CLI and master the key skill of the modern engineer — effective collaboration with AI agents in uncertain conditions.

Ultimately, you will learn to design architecture, manage the product creation process, and use AI as a primary development tool.
