Meet Claude Code & Codex: Your First AI Coding Tasks7:35
Get familiar with Claude Code and ChatGPT Codex through your first hands-on coding tasks. Learn how to interact with both AI coding agents, give clear instructions, and see how they help you complete everyday tasks.
Let's start with the basics and see what these two AI coding agents can actually do.
Build Your First Web App with AI4:39

Better Prompts, Project Context & Agent Control7:55
Learn how to write better coding instructions and give AI agents the project context they need. Explore project-level instruction files, guide implementation decisions, and maintain better control over how Claude Code and Codex modify your application.
You've learned how to guide your agents. But what happens when their code breaks or produces unexpected results? Let's tackle that next.
Debug, Test & Recover AI-Generated Code6:50
AI-generated code can contain bugs, unexpected behavior, and incomplete solutions. In this lesson, you'll learn how to reproduce problems, investigate errors, apply targeted fixes, run tests, and use Git to recover safely.
Once you know how to build and fix your application, it's time to organize your development environment so multiple AI agents can work more efficiently.
Set Up Your AI Coding Workflow: Worktrees, Skills & Permissions7:17
Take your AI coding workflow to the next level. Learn how to create isolated development environments with Git Worktrees, introduce reusable QA Skills, and manage agent permissions and approvals.
By the end, you'll have a more organized workspace ready for parallel AI development.
Now that your workspace is ready, let's put it to the test by having Claude Code and Codex work on separate features simultaneously.

Build in Parallel with Claude Code & Codex: Worktrees & Cross-Agent Review6:23
Discover how to coordinate Claude Code and ChatGPT Codex on the same project without having them interfere with each other's work. Develop Task Search and Task Overview in separate Git Worktrees, then use cross-agent code reviews, targeted fixes, and controlled integration to bring everything together.
You've now built, improved, and integrated your application with multiple AI agents. There's one final step: taking your project beyond your local development environment.
Deploy Your App & Optimize AI Coding Costs6:38
Take SprintOps Lite from local development to a live application using Vercel. Learn how to verify your deployment, understand browser storage limitations, and manage AI coding agent usage and costs more effectively.
With your application deployed and your workflow in place, you've completed the journey from your first AI coding tasks to a practical multi-agent development workflow.
BONUS LESSON: A Gift for Making It This Far0:09
