Modern development isn't just about speed—it's about managing work beyond interaction. This course will teach you how to use the Codex app to coordinate parallel tasks, isolate changes with Git Worktrees and review results through summaries and diffs.

What you'll learn
AI coding tools are fast, but real engineering work often takes time and coordination. In this course, First Look: OpenAI Codex App , you'll learn how to use Codex as a command center for long-running development tasks. First, you'll explore 'Projects' and 'Threads' to manage work clearly. Next, you'll use planning and Git Worktrees to run tasks in parallel and keep changes isolated. Finally, you'll extend Codex with skills and automations to create reliable, repeatable workflows. When you're finished, you'll be able to coordinate parallel agent-driven development with confidence.
