Build Your Own Claude Code

Learn how to code like Antonio by building an agentic coding harness you understand, can extend, and can adapt to your own workflow and future tools.

What you’ll actually build
Over 6 learning days, you’ll build Claude Code — a fully functional AI-powered coding CLI — from scratch.

Not a demo. Not a walkthrough you’ll forget next week. A real tool:

• AI agent integration that reads, writes, and modifies code
• A harness architecture you design and own
• Custom theming and personalization
• The same agentic patterns used in production coding tools

Every day ends with a working milestone. Day 1, you ship something that runs. By Day 6, you have a complete CLI.

This is a 6-day workshop. Lessons will be posted as they are released, with the full archive available at the end of the course.
