Hatch a Codex-format animated pet from a concept, image, or hand-drawn sprite atlas, then install it for clawdex (the Claude Code companion overlay) and Codex. Use when a user wants to "hatch a pet", "make a Claude Code pet", "create a clawdex pet", or convert an existing 8x9 sprite sheet into a `pet.json` package. The skill produces a `pet.json` + `spritesheet.webp` pair under `~/.codex/pets/<name>/` (compatible with both clawdex and Codex). Image generation is delegated to whatever the user has on hand — Claude's web tools, MidJourney, hand drawing, or a pre-made atlas.

Build a [Codex-format](https://github.com/openai/skills/blob/main/skills/.curated/hatch-pet/references/codex-pet-contract.md) animated pet that works in both clawdex and the Codex desktop app. Same atlas, same pet.json, same install path — drop-in compatible.
