What Are Codex Pets?

Codex Pets are virtual companions that live in your OpenAI Codex CLI terminal. Use /pet hatch to hatch a new pet, install a custom pet package, or share your own pet.json and spritesheet.webp package from a public GitHub repository. This hub brings together GitHub, custom pets, sharing, and install examples so AI coding teams can find community pets, inspect source links, copy install commands, and submit new packages from one AIMCP page.

Frequently Asked Questions

How do I install a custom Codex pet?
Copy the install command from any pet listing on this page, then run it inside your OpenAI Codex CLI session. The pet will replace your current companion.
How do I hatch a Codex pet?
Inside the Codex CLI, type /pet hatch to hatch a new pet from your available packages.
How do I create a custom Codex pet?
A Codex pet requires two files: pet.json (metadata and animation config) and spritesheet.webp (sprite frames). Host both in a public GitHub repo and submit it here for review.
Where can I find GitHub, custom pets, sharing, and install examples?
Use the Codex Pets hub to browse community packages, open GitHub source links, copy install commands, compare examples, and submit a custom pet package for review.
What do Codex pets do?
Codex pets are animated companions visible in the Codex CLI sidebar. They grow, animate, and react as you code.
