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