# What are Codex pets?

Codex pets are animated companions associated with the Codex app experience. Codex Pets documents the community package workflow around those companions: previewing spritesheets, inspecting pet.json, downloading example packages, and installing assets locally.

## Community scope

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.

## Package basics

The examples on Codex Pets use:

- pet.json as the manifest.
- spritesheet.webp as the spritesheet image.
- ~/.codex/pets/<pet-id>/ as the example local package folder.
- A 1536 by 1872 pixel spritesheet arranged as 8 columns by 9 rows.
- 192 by 208 pixel frame cells.
