FAQ
- What are Codex pets?
- Small animated companions that live in OpenAI Codex. Each pet ships as a pet.json plus a 1536×1872 spritesheet.webp.
- How do I install a custom Codex pet?
- Open a pet and click Install with Codex. Copy the prompt into Codex; Codex runs the installer and writes pet.json plus spritesheet.webp into your Codex pets folder.
- What is pet.json?
- A small JSON file describing the pet's name, atlas geometry, and animation states. It may include license metadata when the source declares one. No code, no embedded URLs.
- What is spritesheet.webp?
- A 1536×1872 WebP atlas — eight columns by nine rows of 192×208 cells, one row per animation state.
- Can pet packages run code?
- No. CodexPetHub pets are data-only packages. The CLI installs only pet.json and spritesheet.webp, verifies SHA-256 hashes, and never executes package content.
- How does CodexPetHub verify pets?
- Every install manifest carries SHA-256 hashes for pet.json and spritesheet.webp. Codex runs the verified installer, watches the hash checks, and refuses any file that doesn't match.
