This is a Simon Willison blog post describing a fun, benign feature of OpenAI's Codex Desktop app: an animated desktop 'pet' (a pelican on a bicycle) created using gpt-image-2 and open-source skill scripts. There is no security vulnerability, exploit, or malicious activity described in this content.

Technical Analysis

The content describes a legitimate, documented OpenAI feature where a user creates a custom animated pet for the Codex Desktop application using image generation prompts and open-source 'skills' (hatch-pet, imagegen) from openai/skills and openai/codex repos. No prompt injection, tool poisoning, agent impersonation, or any adversarial technique is present. The linked GitHub repos and prompts are transparently documented for a creative/UX feature, not an attack mechanism.
