$hatch-pet create a calm pixel animal Codex pet: capybara coding companion, small glasses, blue shirt, friendly idle and waving animations. Use the shared Codex pet atlas with idle, running, waving, jumping, failed, waiting, and review animations.
How to use
Select a kind, style, mood, and motion profile that match the Codex pet you want to hatch.
Describe the subject, silhouette, colors, accessories, and behavior in concrete language so the generated prompt is usable.
Use the generated $hatch-pet prompt in Codex, then save the returned spritesheet and pet.json package.
Open the preview tool with the resulting spritesheet URL or local package reference to test animation rows before using /pet.
Prompt FAQ
A good hatch-pet prompt should name the subject, kind, visual style, mood, and key readable details. It should also ask for the shared Codex pet atlas animations so the output covers idle, running, waving, jumping, failed, waiting, and review states.
No. Describe the character and the important behavior states, then let the generation workflow produce the frame set. Over-specifying every frame can make the prompt brittle and less visually consistent.
You should avoid publishing pets that depend on protected characters, logos, or brand assets unless you have the rights. Safer prompts describe an original companion with its own silhouette, colors, and personality.
