Generate on-brand marketing images via Codex's built-in image_generation tool.
Trigger when user asks to: (a) create marketing assets (ad / logo / slide /
product-mockup / scene / lighting-transform / LinkedIn-or-social carousel)
for a specific brand, (b) extract
or build a brand profile (DESIGN.md) from URL / Tailwind config / tokens.json /
Figma Variables / CSS custom props / description / existing brand asset, (c)
maintain on-brand consistency across multiple image jobs for the same brand.
Do NOT trigger for: UI code generation, frontend reference imagery (use
imagegen-frontend-web instead), video generation, or general image editing
without brand context.
RUNTIME: Requires OpenAI `image_generation` tool (gpt-image-2 via Responses
API). Native to Codex (CLI / App / web). Claude Code users need an MCP
server that exposes image generation. If the tool is unavailable, this
skill HARD-STOPS with remediation guidance — it does NOT fall back to
HTML/CSS/Canvas rendering.
