Codex pet basics

What are Codex pets?

Codex pets are animated companions used inside the Codex app experience. This community site focuses on custom pet packages: a pet.json manifest, a spritesheet image, preview tools, and install guidance for local Codex workflows.

Is Codex Pets an official OpenAI site?

No. Codex Pets is an independent community utility. It links to official OpenAI Codex sources for Codex product context, while the pet package documentation is maintained by this site.

What files does a Codex pet package use?

The package examples on this site use pet.json and spritesheet.webp inside a local ~/.codex/pets/<pet-id>/ folder, with the manifest pointing to the spritesheet file.
