What it solves

It provides a structured system for creating sparse, minimal editorial posters with a specific "indie-zine" aesthetic. It solves the problem of generating consistent, production-ready image prompts or actual images that avoid commercial, glossy, or overly dense layouts in favor of a quiet, paper-textured visual style.

How it works

Designed as a "skill" for Codex or compatible runtimes, it uses a set of reference documents (style systems, prompt compilers, and variation engines) to transform a theme, photograph, or article idea into a visual metaphor. It then compiles this into a detailed four-paragraph image prompt that specifies a 3:5 aged-paper canvas, high negative space (70-90%), specific typography, and a single high-chroma color accent, while applying quality gates to filter out unwanted generic symbols.

Who it’s for

Users of Codex or similar AI skill runtimes who want to generate minimal, artistic editorial imagery or reusable visual systems for zines and posters.

Highlights

• Multiple Request Modes: Supports direct generation, prompt-only output, reference analysis of existing images, and photo-to-poster conversion.
• Strict Visual Identity: Enforces a specific aesthetic including risograph, halftone, and letterpress defects on aged paper.
• Reference Analysis: Can inspect image folders to extract fixed and variable rules to create a reusable visual system.
• Quality Control: Includes a quality gate and regression evaluations to prevent the appearance of unrequested symbols or pictograms.
