Hatch Pet
Hatch a pet inside Codex
Codex includes a built-in skill called Hatch Pet. With one short prompt, you can generate a complete animated companion: 9 states at 1536×1872. From idea to a working desktop sprite usually takes about five minutes.
Hatch your pet
In the Codex chat, run /Hatch Pet. Describe the pet you want: an idea, a mood, or an object from your desk. The skill generates the spritesheet and animation automatically.
Prompt hint:For example, “a rabbit holding an AK that reminds me to stretch in the afternoon” is much more distinctive than just saying “cute pet.”
Enable it
Open Knock Pet, go to Settings > Pet Appearance, then choose Import. Pets generated by Codex are usually saved under ~/.codex/pets/<name>. After importing, it will live on your desktop.
Share it to the Knock Pet community
On the settings page, click “Share to community” on the right side of the pet card. We host and share the files so other people can install it easily.
