What is it?
GC Minimal Zine Poster is a Codex skill for producing sparse, paper-texture editorial posters. Given a theme, sentence, object, mood, photograph, or set of reference images, it can generate a finished raster poster, return a reusable image-generation prompt, or extract a visual system from references without copying their layout.
The default output is a vertical 3:5 aged-paper canvas with 70%-90% negative space, one small imageable subject, restrained typography, and one high-chroma accent color. Visual defects such as xerox, risograph, halftone, or scanned-paper texture are part of the style. The skill explicitly avoids glossy mockups, 3D rendering, neon, dense scrapbook layouts, and long text blocks.
The skill offers five request modes: Generate, Photo Input (which preserves a supplied photo's subject while changing layout and paper treatment), Reference Analysis, Prompt-only, and Analyze + Generate. It is installed by cloning the repository into the Codex skills directory.
