Welcome to the Claude Code Command Tutorial.
Instead of just listing commands like a dictionary, we believe in Learning by Doing. In this tutorial, you will build a real-world application: a Pomodoro Timer with a Todo List.
Why this project?
- It involves UI (terminal or web).
- It requires state management (timers).
- It needs persistence (saving tasks).
- it has clear milestones.
What you will master:
- Project Setup:
/init,/config - Architecting:
/plan - Automated Coding: Subagents and tool execution
- Advanced Workflows:
/compact,/resume,/add-dir - Security: Permission modes and safe execution
By the end of this 12-chapter journey, you won't just know the commands—you'll know how to architect and orchestrate AI-driven software development.
Let's get started!
