How to set up a Codex pet in under 10 minutes:
Open a Codex chat (not your terminal — the skill needs to run inside Codex)
Run $skill-installer hatch-pet
$skill-installer hatch-pet
Restart Codex
Use the /hatch-pet slash command to generate your first pet
/hatch-pet
Go to Settings → Appearance → Pets to set it as default
Run /pet to wake it up
/pet
Your pet will live in an overlay at the bottom right of your screen, showing you task status while you work in other apps.
Worth the 10 minutes.
