Codex pets hub▌
Companion page to our registries (/skills, /designs): quick orientation for Codex desktop pets, the hatch-pet skill path, and downloadable prompt blocks—without pretending we host binaries (OpenAI builds those).
Highlights & archetypes
Custom
Custom hatch-pet creations
“Your repo mascot, terminal ghost, or brand-safe glyph.”
Created via the curated hatch-pet skill: sprite atlases, validation, packaging. Best for teams that want a consistent identity across demos.
Community
Community vibe-code mascots
““Finder guy” and other social-era spritework.”
Third-party writeups (e.g. 9to5Mac, May 2026) show how users iterate pets outside official art packs—fun, but treat licensing and polish seriously before distributing.
Workflow cheat sheet
- Enable pets in Settings → Appearance → Pets (Codex desktop).
- Use
/pet, Wake Pet, or Tuck Away Pet per in-app docs. - Install hatch-pet (GitHub source), reload skills, then run curated prompts.
- Validate packaged output against SKILL.md before checking sprites into a shared repo—pets are still untrusted content until reviewed.
