Codex pet explainer
Codex pets are animated companions associated with the Codex app experience. This page separates official Codex context from the community package workflow documented by Codex Pets.
A Codex pet package is a small local asset bundle used by Codex pet workflows. The examples on this site use a pet.jsonmanifest and a spritesheet.webp image, then preview the same asset contract before users install it locally.
In the Codex app, pets behave like lightweight animated companions. In this community workflow, the practical job is package handling: choose a finished pet, inspect its 9-state spritesheet, download the package, and place it in the local Codex pets folder before selecting it in Codex.
Use the gallery to compare finished packages, the preview tool to inspect a spritesheet URL, the install guide to add a package locally, or the builder when you want Codex to generate a new hatch-pet brief.

Codex Pets is an independent community utility. OpenAI's official pages document Codex itself; Codex pet package notes on this site are community-maintained workflow documentation based on Codex app behavior and local package testing.
For package-level work, start with the gallery to inspect finished examples, then use the install guide to verify the manifest, atlas dimensions, and local folder shape.
