Overview
This skill teaches your agent to create and edit images with OpenAI's GPT Image 2 and 2.5 models through a bundled command-line tool. You describe the picture, or give it reference images and an optional mask; it asks which model to use, then saves the finished PNG, JPEG or WebP file. It comes with a gallery of more than 160 example prompts, from posters to diagrams. It suits creators and makers who have an OpenAI API key.
It pairs the image tool with a large, sorted prompt gallery, so your agent can start from a worked example instead of a blank prompt.
Try these first
Start with the first one: it is a small task you can check easily.

- Show me three gallery directions for a cafe menu poster before generating anything.
- Generate the Boston Spring poster from the skill gallery.uses API credit

What you get
From the creator's documentation.
| Output | What it is | Reads |
|---|---|---|
| Model choice | Asks you to pick Flare, Sunburst or Image 2 when the model is unclear | Your request |
| Prompt gallery | More than 160 numbered example prompts in 31 categories to start from | Skill files |
| New images | Posters, icons, product shots and diagrams made from your description | OpenAI API |
| Reference edits | Restyles or combines images you give it, with an optional mask for one area | OpenAI API |
| Saved files | PNG, JPEG or WebP files written to the path you choose | Your computer |
Good to know
You need a poster, product shot or diagram and want to describe it in words. The skill asks which GPT Image model to use, runs the bundled command-line tool and reports where the image file was saved.
Limits
- Every image call uses your own OpenAI API key and can cost money. The tool reads the key from your environment, a .env file or ~/.env.
- The skill asks before a model switch or extra paid variants. The xhigh and max quality settings and transparent backgrounds work only on the 2.5 models.
