OpenAI has really been cooking lately.
They’ve gone CRAZY on capabilities and features for Codex, their fast-growing Claude Code competitor.
In the last couple of weeks, Codex got in-app browser use, image generation, and computer use.
But today’s newsletter isn’t about that. Today’s newsletter is about adding some fun to Codex.
What are Codex pets?
Codex pets are optional companions for the Codex app.
They are not for productivity. They’re for fun!
One thing to note is that Codex pets are only available in the app, so if you’re using the CLI you’re out of luck.
If you’re curious about Codex pets, you’re in good company. The AI-Augmented Engineer is dedicated to helping software professionals use AI to make meaningful improvements to their work.

If you already have Codex installed and get the basics, you just have to install the hatch-pet skill.
$skill-installer hatch-pet
Note that you should run this inside a Codex chat, not just in your terminal.
Once it’s done, restart Codex.
I’m glad OpenAI adopted the Skill standard, it makes it easier to switch back and forth between Claude Code.
