Usage

Just talk naturally about creating visuals. The skill auto-triggers when you mention creating, generating, or designing images for products, social media, marketing, or POD.

**Examples:**

"create a streetwear t-shirt design with skulls and flames for my Etsy shop"

"generate an instagram post image for my artisanal coffee brand"

"make a cute kawaii cat design for coffee mugs"

"I need a minimalist poster design with just the word BREATHE"

What It Does

1. Parses your context - Accepts any input format (free-form, structured, or minimal keywords)
2. Routes intelligently - POD designs get niche-specific design rules; commercial images get camera specs and platform optimization
3. Applies design intelligence - 10 validated niche modules, visual hierarchy rules, color systems, anti-pattern guards
4. Outputs structured JSON - Ready-to-paste prompt with full context analysis and metadata
