codex-image-in-cc
Claude Code plugin that exposes Codex CLI's built-in imagegen skill as /codex-image:* user-invoked plugin skills.
The plugin does not implement image generation itself. Each plugin skill dispatches to codex exec --full-auto and lets Codex's imagegen skill drive the built-in image_gen tool, use attached reference/edit images, save the final artifact, and print a SAVED: <path> line for each output.
Requirements
- Claude Code with plugin support.
@openai/codex CLI v0.142.0 or later (v0.144+ recommended — it moves image generation to the extension-backed tool the instruction prefixes are written for).- An active
codex login session.
- Node.js 18.18 or later.
OPENAI_API_KEY is not required for the default built-in path. Codex can use either a ChatGPT login or API-key login.
Install
From GitHub (recommended)
claude plugin marketplace add KingGyuSuh/codex-image-in-cc
claude plugin install codex-image@codex-image-in-cc
From a local clone
git clone https://github.com/KingGyuSuh/codex-image-in-cc.git
cd codex-image-in-cc
claude plugin marketplace add "$PWD"
claude plugin install codex-image@codex-image-in-cc
Then restart Claude Code if needed. Default install scope is user; pass --scope project or --scope local to limit installation.
Plugin Skills
/codex-image:status
/codex-image:generate "A watercolor moonlit library, save to images/library.png at 1024x1024"
/codex-image:generate --ref style.png --ref "character ref.png" "A 9:16 scene using those references, save to images/scene.png"
/codex-image:generate "5 logo variations of a brass compass on white, save under images/logos/"
/codex-image:edit input.png "Replace the background with a clean white studio backdrop, save to edited.png"
Apart from leading reference-image flags on generate and the input-path split on edit, the natural-language prompt is passed through to Codex's imagegen skill. Express output paths, sizes, quality, count, transparency, etc. as natural language inside the prompt — imagegen interprets them. Defaults: when no path is specified, files land under ./codex-images/<UTC-timestamp>-<n>.png.
For /codex-image:generate, leading --ref <path>, --reference <path>, or --image <path> arguments are attached to the Codex turn via codex exec --image and treated as generation references, not edit targets. Repeat the flag for multiple references (at most 5 — the built-in image tool's reference cap). Quote paths with spaces. Use -- before the prompt if the prompt itself starts with a flag-like token.
For /codex-image:edit, the first whitespace-separated token is the input image path. Quote it if the path contains spaces (e.g. /codex-image:edit "my photo.png" tint blue).
Development
npm test
npm run validate:plugin
npm run status
claude --plugin-dir .
After editing plugin skills during a claude --plugin-dir . session, run /reload-plugins.
Image generation consumes a Codex agent turn plus the built-in image generation tool usage.
