Imagegen Codex Skill

Generate and edit project images with Codex's native image tool.

Docs reviewedChecked 2026-09-10Runtime not tested

What it adds

The official sample skill covers generation, editing and transparent images. It prefers the built-in image tool and treats the API-backed CLI as a separate, explicitly selected fallback.

Get set up

Check whether your Codex host already exposes the image generation skill or tool.
Ask for the image or edit, providing references and output requirements.
Use the built-in tool path when available; it does not require an OpenAI API key.
If you explicitly choose the fallback CLI/API path, follow the sample's separate environment and setup instructions.

Read the installation source

Before you install

A Codex host with the built-in image_gen tool
Reference image for edits when relevant
Separate API credentials/runtime only if choosing the fallback

Compatibility & limitations

Native Codex capability where available

Cursor: Copying this skill does not provide Codex's tool in Cursor. Cursor has its own native image generation.

A source sample does not guarantee feature availability for every account or host.
The no-API-key statement applies to the built-in path, not the fallback.

This listing is based on source documentation. We have not installed or runtime-tested this asset.

How it fits together

Native alternative to an external provider for ordinary image generation and editing.
