Create a Custom Codex Pet (No Code Required)

In this guide, you will learn how to make a custom animated desktop pet like Clippy. It will sit on your screen and give you status updates from your Codex agent as it works.

• Codex users who want a lightweight way to monitor active tasks without keeping the whole app open.
• People who like customizing their workspace, but do not want to hand-build animation files or sprite sheets.
• Teams making repeatable Codex workflows who want a small visual reminder that an agent is running, waiting, or ready to review.

You will create a custom animated Codex pet, add it to the Codex desktop app, and wake it as a floating status companion.

Behind the scenes, the pet is more than one static image. The hatch-pet skill turns your mascot idea into the files Codex needs for different pet states and animations.

• The Codex desktop app (https://developers.openai.com/codex/app) with the latest update
• You could also do this in Codex terminal with /pet and @hatch-pet

Once you have one pet working, turn the same process into a repeatable customization checklist: update the pet, tune the app theme, set your preferred Codex personality, and document project rules in AGENTS.md.

You can also browse the Petdex GitHub repo (https://github.com/crafter-station/petdex) for user-created pet inspiration. Treat outside pet files like any other community-created asset: inspect what you are installing, avoid untrusted commands, and use the gallery for ideas when you are not sure what style you want.
