About
Built for the workflow around Codex pets.
Codex Pets is a small utility site for people creating or installing custom Codex pets. It focuses on the parts around the generation step: previewing spritesheets, validating pet.json, building clearer hatch-pet prompts, and explaining the local install contract.
What this tool does
The site renders example pets with codex-pets-react, shows the shared atlas dimensions, validates basic manifest fields, and gives you copyable install snippets. It is meant to reduce package mistakes before you move a pet into ~/.codex/pets.
How the catalog is maintained
Catalog pages combine contributor attribution, package metadata, nine-state visual previews, manifest checks, install steps, and direct file inspection. Those checks help people evaluate whether a package works; an author label is attribution, not a blanket license for every name, character, or image in the package.
Rights and corrections
We do not claim ownership of contributor artwork or third-party characters. If a package is misattributed, uses protected material without permission, or should be removed, use the contact page with the package URL and supporting details. We can correct the public record or remove the package while the concern is reviewed.
What this tool does not do
This site does not generate final spritesheets, host community uploads, manage accounts, or grant rights to third-party artwork. Finished pet artwork still comes from a generation workflow such as hatch-pet or a separate image pipeline.
Relationship to Codex
Codex Pets is an independent community utility. OpenAI's public Hatch Pet skill documents the current generation workflow; package notes on this site are community-maintained from public sources, Codex app behavior, and local package testing.
