What is Codex?
Codex is OpenAI’s AI coding agent. It can work with a project, make changes, and help with tasks such as implementation, debugging, testing, and review. The working setup determines which files and tools it can access.
What can you do
with Codex?
Project-aware work

Work through supported app, command-line, and editor experiences.
Start with one useful task.
A practical exercise to explore how Codex could fit your work.
- Describe the change, the page or files involved, and what a good result looks like.
- Let Codex inspect the existing project and produce a focused implementation.
- Review the result in the browser, check the diff, and publish through your normal repository workflow.
