CODEX PET FAQ
Before you install.
Where does a Codex pet install?
Native packages go to ~/.codex/pets/, or $CODEX_HOME/pets/ when that environment variable is configured.
How do I activate it?
In the desktop app, refresh Settings → Pets and choose the pet. In an interactive Codex CLI session, enter /pets or /pet.
Does the Codex IDE extension show pets?
No. The IDE extension does not currently provide a pet picker or floating overlay. Use ChatGPT desktop or a supported Codex CLI terminal.
