Hatch a Codex pet for your workflow
Hatch Pet is a focused guide and gallery for the Codex pet idea: a tiny animated companion that makes AI coding work easier to read at a glance.
Use the homepage to understand what a Codex pet can signal, how the /pet command fits into the workflow, and why a friendly status buddy can be more useful than another dashboard.
Tiny companion, clear progress cues, calmer Codex pet sessions.
What is a Codex pet?
A Codex pet is an expressive coding companion that can sit beside an AI workflow and translate invisible agent activity into a visible mood. Hatch Pet turns that idea into a clear product surface: a concise /pet guide, a status language, a Codex pet gallery, and a launchpad for custom animated companions. The goal is not to distract you; the goal is to make running, waiting, blocked, reviewing, and finished work feel readable without opening another panel.
Pet gallery
Browse Codex pet companion concepts inspired by public pet galleries: cozy creatures, focused helpers, mischievous mascots, and more. Each card links the pet personality to a practical workflow moment.
State-first design
Frame each Codex pet around useful work states such as idle, running, thinking, success, blocked, retrying, and done, so the animation has a purpose beyond decoration.
Custom hatch ideas
Shape a Codex pet personality, vibe, color palette, and animation direction before turning it into a polished companion, sprite sheet, or installable overlay.
Built for makers
Keep the Codex pet experience lightweight, shareable, and easy for developers to understand at a glance, with honest copy about what is live now and what belongs to future runtime work.
Why a Codex pet belongs in the workflow
The best Codex pet is not only cute. It makes background work easier to notice without adding another dashboard. When an AI agent is planning, editing, testing, or waiting for review, a small visual companion can reduce uncertainty and give you a softer rhythm for long coding sessions.
How to enable Hatch Pet in Codex
Codex ships a Hatch Pet skill for creating and running custom animated pets. The practical flow is: install the skill, type /pet, describe the companion you want, restart Codex, then select the generated pet from Appearance settings. The skill produces a Codex-compatible package with a 9-state 1536x1872 spritesheet, pet.json manifest, and local files under ~/.codex/pets/<name>.
Install the Hatch Pet skill
Open Codex, go to Skills in the top navigation, find Hatch Pet, and install it. This adds the /pet creation flow plus the packaging rules Codex expects.
Type /pet and describe the idea
In Codex chat, type /pet. Give the pet a specific concept, vibe, object, or reference direction. Specific prompts travel further: a bubble-tea otter is stronger than a generic creature.
Let the skill hatch the package
The Hatch Pet skill plans the sprite style, generates the animation rows, validates the atlas, and writes pet.json plus spritesheet.webp. The target format is 8 columns by 9 rows, with transparent unused cells.
Activate and share it
Restart Codex, open Settings, go to Appearance, choose Pets, and select the new custom pet. The pet folder lives at ~/.codex/pets/<name>, so you can zip that folder and submit it to Petdex when you want to share it.
