A skill that generates images and visual assets using OpenAI's Image API for UI design, mockups, and illustrations.
About
This skill wraps OpenAI's Image API to generate and edit images for design assets. Developers use it to quickly produce UI mockups, icons, illustrations, social cards, and visual references without leaving their agent environment. It integrates directly into planning workflows, triggered by phrases like 'generate image', 'create image', or 'icon design'. The skill advertises itself through Open Design's discovery system so agents can invoke it by name or trigger phrase during project planning and asset creation.
- Generates images via OpenAI's Image API with triggers like 'generate image', 'create image', 'icon design'
- Produces design assets: UI mockups, icons, illustrations, social cards, visual references
- Integrates into agent planning workflows for rapid asset creation
- Discoverable through Open Design catalog for automatic agent invocation
- Curated from OpenAI's official skills repository with upstream maintenance
