SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires Pillow, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Automates the end-to-end creation of Codex-compatible animated pet sprites from concept art, screenshots, or references, generating a fixed atlas and packaging it for the Codex ecosystem.

Core Features & Use Cases

  • Generate a Codex atlas (8x9, 192x208 per cell) from base art and reference inputs, including per-row strips and layout guides.
  • Produce deterministic spritesheet assembly, QA materials (contact sheet, previews), and a ready pet.json + spritesheet.webp package.
  • Integrate with imagegen as the primary generation engine while preserving identity across frames and rows.

Quick Start

Launch hatch-pet with your reference images to generate a Codex-compatible animated pet atlas and package it for use in the Codex ecosystem.

Frequently Asked Questions about hatch-pet

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate an animated pet spritesheet atlas from reference art?▼

To generate an animated pet spritesheet atlas, provide concept art or reference images to the system, which orchestrates base art generation and deterministic layout into a fixed 8x9 grid. This produces a final spritesheet.webp packaged with QA materials for immediate use.

Can I use Pillow to package spritesheet atlases for the Codex ecosystem?▼

Pillow is required as a dependency to package spritesheet atlases for the Codex ecosystem. The process relies on deterministic scripts and the imagegen system to assemble per-row strips and layout guides into a final spritesheet.webp with validation artifacts.

What is a Codex-ready animated pet atlas and what files are included?▼

A Codex-ready animated pet atlas is a fixed 8x9 grid layout, with 192x208 pixels per cell, generated from base art. The package includes pet_request.json, decoded base and state PNGs, final spritesheet.webp, validation.json, and QA contact sheets.

Does the spritesheet generation process preserve character identity across animation frames?▼

The spritesheet generation process preserves character identity across animation frames by using canonical identity references and layout-consistent prompts. This ensures the animated pet remains visually consistent throughout all rows of the generated atlas.

What do I need to provide to start automated pet sprite packaging?▼

You need to provide concept art, screenshots, or reference images to start automated pet sprite packaging. The system uses these inputs to orchestrate base art, generate per-row animation strips, and package the final spritesheet with validation artifacts.

Are there limitations to the fixed 8x9 atlas layout for animated sprites?▼

The fixed 8x9 atlas layout with 192x208 pixel cells is a strict constraint for Codex compatibility. Any input concept art must conform to this deterministic grid structure, meaning custom atlas dimensions or varying cell sizes are not supported.
