Editor Skin Nova

Editor Skin Nova is a configurable skin generator for code editors. It defines a set of design tokens (colors, typography, spacing) that can be exported as CSS variables or JSON for use in editor themes. The tool targets frontend teams, IDE integrations, and product developers who want a consistent, branded coding experience.

Conceptually, Nova separates design decisions from editor implementation. Given a base_palette and font_family, it derives colors for backgrounds, text, syntax highlighting, and UI chrome. It validates contrast against WCAG thresholds and provides fallbacks for missing fonts via system monospace stacks.

Core features include token export in CSS variables; adjustable typography and spacing; automatic contrast evaluation; and mappings to common editors (Monaco, CodeMirror, Ace) via token names. Use cases include web IDE theming, white-label editors in SaaS apps, and internal tools that require rapid, consistent theming.

Unique value lies in explicit token contracts and reusable palettes that can be shared across projects. This reduces duplication, improves consistency, and accelerates design-system onboarding. By separating design tokens from editor code, Nova enables scalable theming across multiple editors and environments.
