description	Generate Cowrite article illustrations, Xiaohongshu images, presentation visuals, covers, and structured diagrams with Codex's built-in image_gen tool. Use for 配图, 整篇配图, 小红书图片, PPT 图片, 封面, 逻辑图, 流程图, 架构图, or any Cowrite task that needs raster image generation.

Image Studio

Create polished raster images with Codex's built-in image_gen tool. Never call LabNana, Gemini, OpenAI API/CLI, a local generation script, or any other external image provider. Do not require or request an API key.

If the runtime does not expose the built-in image_gen tool, stop and explain that image generation requires Codex with built-in image generation. Do not silently downgrade or insert a placeholder.

Image types

Type	Default ratio	Reference
Xiaohongshu cover or series	3:4	references/types/xhs-cover.md
Presentation visual	16:9	references/types/ppt-illustration.md
Structured chart or diagram	adaptive	references/types/chart.md
Article logic illustration	16:9	references/types/article-logic.md

Read the matching type reference before prompting. For style, select one file from references/styles/ and keep its palette, typography, spacing, and visual language intact.

Confirmation rules

Confirm these four decisions before generation:

1. image type and aspect ratio;
2. complete content and required exact text;
3. one visual style;
