|A Claude Code skill that generates custom OpenAI Codex Pets from a single reference image via the RunComfy CLI. It produces a Codex-compatible spritesheet (1536x1872, 8 columns x 9 rows) and pet.json manifest using GPT Image 2 and ImageMagick, without requiring Codex Pro or an OPENAI_API_KEY.
Overview
Codex Pet is a Claude Code skill that turns a single source image into a fully functional custom OpenAI Codex Pet. It produces the exact spritesheet atlas (1536x1872, 8 columns x 9 rows of 192x208 cells) and pet.json manifest that Codex expects, then drops them into the Codex pets directory for immediate use. The skill calls GPT Image 2 edit once via the RunComfy CLI to create a canonical pixel-art pose, then programmatically assembles all 9 animation rows using ImageMagick micro-transforms, requiring only a RUNCOMFY_TOKEN with no Codex Pro subscription or OPENAI_API_KEY needed.
Key Features
- Single-image pet creation: Transforms any reference image into a complete Codex Pet with one RunComfy API call plus local ImageMagick processing
- Full 9-state animation atlas: Generates all 9 animation states Codex expects (idle, running-right, running-left, waving, jumping, failed, waiting, running, review) with subtle micro-transforms
- No Codex Pro required: Uses RunComfy's GPT Image 2 endpoint instead of the Codex-internal
$imagegensystem, needing only a RUNCOMFY_TOKEN - Batch generation support: Can process a folder of source images to create multiple custom Codex Pets in one run
- Exact Codex compatibility: Output matches the official
hatch-petskill format precisely, so Codex treats it identically to built-in pets - Chibi pixel-art style: Follows Codex's visual house style with exaggerated chibi proportions, limited palette, and clean outlines
Who is this for?
- OpenAI Codex users who want custom desktop pets without a Codex Pro subscription
- Developers entering the Codex Pet contest who want to use alternative image models behind the visuals
- Anyone who wants to batch-generate multiple Codex Pets from a folder of source images via CLI
