Install hatch-pet
Install hatch-pet in Codex first, then restart Codex if the skill installer asks for a restart before you create the pet.
Create custom Codex pets
Write a specific prompt with the pet name, species, mood, colors, and pixel style so the generated result can become a usable Codex pet package.
Check pet.json and spritesheet.webp
A finished package should include pet.json for the pet name and description, plus spritesheet.webp for the animation preview used by Codex Pet Gallery.
Publish the finished pet
Upload the finished package to Studio so visitors can preview the pet, copy the install command, download the files, and share the page.
Publish your pet
Put your pet on a page people can use.
Upload pet.json and spritesheet.webp together. The page shows the preview, file links, package download, creator name, and related pets.
