Required fields
Use id for the package name, displayName for the title, description for the page copy, and spritesheetPath for the animation file.
Manifest reference
Codex pet.json format
pet.json tells the gallery what the pet is called, how to describe it, and which spritesheet file to use.
{
"id": "happy-dog",
"displayName": "Happy Dog",
"description": "A cheerful pixel dog for focused coding sessions.",
"spritesheetPath": "spritesheet.webp"
}Naming rules
Keep ids lowercase and simple. The current uploader expects the referenced animation file to be named spritesheet.webp.
Description rules
Write one specific sentence. Mention what the pet is, not generic filler like cute pet or nice mascot.
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.
