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.
What this tool does not do
This site does not generate final spritesheets, host community uploads, manage accounts, or review intellectual-property rights. 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 official pages document Codex itself; Codex pet package notes on this site are community-maintained workflow documentation based on Codex app behavior and local package testing.
