This project is a Claude Code skill, meaning it is a small add-on folder that Claude Code can discover and use during a coding session. Its job is to generate image assets by calling on the Codex CLI's built in image_gen tool, then optionally turn the result into a real see-through cutout image. It solves two specific problems that are easy to trip over. First, some installs wrap the codex command in a shim that adds flags an older version of codex does not understand, which causes errors. This skill looks past those wrapper shims and calls a real codex binary directly, and you can also point it at a specific one yourself. Second, when you ask image_gen for a transparent background, it does not actually give you one. It fakes it with a see through looking checkerboard pattern baked into the image. This skill works around that by generating the image on a plain solid color background and then removing that color afterward, which produces a genuine transparent cutout. The process works in four steps: you write a prompt, the image gets generated, the result gets checked, and then, if you want transparency, the background gets removed. To use it, you need the Codex CLI installed and logged in, plus bash and python3. ImageMagick is an optional extra for background removal and checking images across different operating systems. It works on macOS or Linux. Installation means copying the skill folder into the right location, either for every project on your machine or just one project. After that, you can simply describe the image you want in plain language and the skill will activate. There are also two scripts you can call directly if you prefer manual control over generating and removing backgrounds. The project is released under the MIT license.
