What problem does it solve?
Codex removes ambiguity in UI generation by enforcing a radically minimal, typography-first design system that keeps hierarchy, spacing, and interaction states consistent.
Core Features & Use Cases
- Blank-canvas foundations: Defines a pure edge-to-edge surface aesthetic with black as the primary filled color and typography as the primary structure.
- Token-driven styling: Establishes explicit typography scale (Open Sans + JetBrains Mono), spacing rhythm, and color tokens for primary/semantic feedback.
- Accessible interaction guidance: Requires WCAG 2.2 AA alignment with keyboard-first behavior and visible focus states for all relevant components.
- Component rules with quality gates: Provides do/don’t constraints, required interaction states, and testable QA checklists suitable for design-system implementation.
Quick Start
Use the codex skill to generate design-system rules and implementation-ready component guidance for a new minimal UI from scratch.
