Codex Pet
If you want a custom Codex Pet but don't have Codex Pro or access to the built-in `$imagegen`, this skill gives you a clean alternative route through RunComfy's API. It takes a single reference image, makes one GPT Image 2 edit call to generate a canonical chibi pose, then uses ImageMagick to programmatically build all nine animation rows with pixel-perfect micro-transforms. The output is identical to what OpenAI's official `hatch-pet` produces: a 1536x1872 spritesheet and pet.json that drop straight into your `.codex/pets/` folder. You'll need a RunComfy token and ImageMagick installed locally. The whole pipeline runs in about two minutes and costs one image generation call instead of 72.

Codex Pet generator on RunComfy. Turn one source image into a Codex-compatible custom Codex Pet — pet.json + spritesheet.webp — drop it into ${CODEX_HOME:-$HOME/.codex}/pets/<name>/, Codex picks it up next to the 8 built-in Codex Pets.

What a Codex Pet is
OpenAI Codex Pets (released May 2026) are pixel-art animated companions that float over your desktop while Codex codes — they react to mouse interaction and Codex status (scratching head when thinking, popping a speech bubble when a task completes). Codex ships with 8 built-in Codex Pets and supports custom Codex Pets installed locally as a folder under ${CODEX_HOME:-$HOME/.codex}/pets/.
