## What it does

The skill creates raster visuals for blog posts, technical writing, and documentation. Ask for a concept illustration, an architecture diagram, or a visual explanation of a workflow. In Codex, the built-in route is the best first option because it does not need `OPENAI_API_KEY` when `image_gen` is available.

Outside Codex, the skill runs `scripts/generate_image.py`. With `auto`, the script tries OpenAI through `OPENAI_API_KEY`, then switches to Gemini with `GEMINI_API_KEY` if the first route cannot generate the image. You can set the provider, model, aspect ratio, image size, and style prefix. The script defaults to English prompts, a `16:9` ratio, `1K` output, and a clean minimalist style.

API generation requires the matching provider key. The Codex route depends on access to the built-in `image_gen`; when that tool is unavailable, the workflow falls back to the script and checks the provider credentials.

## When to use it
- create an illustration for an article
- draw an architecture diagram
- prepare a visual for documentation
- switch generation from OpenAI to Gemini
- set an image ratio and size

## Example prompts
- Create an illustration for the article about vector search and save it as `images/vector-search.png`.
- Draw a system architecture diagram with arrows showing data flow and use a `16:9` canvas.
- Generate the image through an API at `2K` size, using a clean technical illustration style.
