Browser-based studio to create, remix, and download custom animated pets for OpenAI Codex.
Codex Pet is an independent, browser-based studio designed for creating, remixing, and downloading custom animated pet packs for OpenAI Codex Desktop. It allows users to build, edit, and preview these pet packs directly in their browser, focusing on frame-by-frame creativity.
A Codex Pet is a local custom pet package for Codex Desktop. A valid package contains pet.json and spritesheet.webp and is installed under ~/.codex/pets/<pet-name>/.
Codex Pet accepts transparent WebP spritesheets without enforcing a fixed pixel size. Reviewers inspect the uploaded image and animation layout before publishing.
Run $skill-installer hatch-pet in Codex, restart Codex, then start a fresh conversation and run $hatch-pet with a pet concept or reference image.
