What's inside
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 --sandbox workspace-write 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.
@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). Codex CLI 0.151+ removed --full-auto from codex exec; plugin 0.2.1+ dispatches with --sandbox workspace-write instead, which older and current releases both accept.codex login session.OPENAI_API_KEY is not required for the default built-in path. Codex can use either a ChatGPT login or API-key login.
claude plugin marketplace add KingGyuSuh/codex-image-in-cc
claude plugin install codex-image@codex-image-in-cc
git clone https://github.com/KingGyuSuh/codex-image-in-cc.git
cd codex-image-in-cc

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.
/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).
Image generation runs as a Codex agent turn (the "orchestrator") that calls the built-in image tool. The plugin picks a stronger orchestrator model/effort when your account has one, without breaking accounts that don't: it reads your live model catalog via codex debug models and selects the first available rung of a preference ladder —
gpt-5.6-luna high → gpt-5.6-terra medium → gpt-5.6-sol high → gpt-5.6-sol low
If none of those are available to your account (for example on ChatGPT Free), or the probe fails, the plugin passes no model flag and Codex uses its own configured default — image generation still works. /codex-image:status shows which orchestrator was resolved.
To force a specific model and effort, set both environment variables (setting only one is an error):
export CODEX_IMAGE_MODEL=gpt-5.6-terra
export CODEX_IMAGE_EFFORT=high # none|minimal|low|medium|high|xhigh|max|ultra
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.
