What problem does it solve?
You need consistent UI and marketing visuals while building but lack a documented agent workflow tied to OpenAI image generation.
Who is it for?
Solo builders already using OpenAI APIs who want agent-discoverable image generation during frontend and asset work.
Skip if: Teams that need a self-hosted diffusion pipeline, print-ready brand systems without API costs, or video generation workflows.
When should I use this skill?
User says generate image, create image, image gen, openai image, icon design, or mockup for OpenAI Image API project assets.
What do I get? / Deliverables
The agent invokes imagegen with clear triggers and points you to install the upstream openai/skills package so mockups, icons, and cards can be produced in-session.
- Generated or edited image assets for UI, icons, or social use
- Agent-ready invocation path via skill name or triggers

Journey fit
Visual asset creation happens while you are shaping the product surface, not after distribution. Frontend subphase covers mockups and marketing visuals that ship with the app and landing experiences.
How it compares
OpenAI Image API skill catalogue entry—not Midjourney prompts or a Figma replacement.
