What problem does it solve? Design tokens often live in multiple places (JSON source files and CSS theme files), and keeping them in sync manually leads to drift, inconsistent naming, and missing dark-mode variants. This Skill manages the full lifecycle of design tokens in the StyleSeed design system so changes stay consistent across every file. ## Core Features & Use Cases - List tokens: Read and display color, typography, spacing, radius, or shadow tokens from their JSON source files in a formatted table. - Add tokens: Insert a new token into the JSON source, the :root CSS custom properties, the @theme inline Tailwind block, and the .dark block when a dark-mode variant is needed. - Update tokens: Modify values in both the JSON source and css/theme.css, then check components for direct usage that may need updating. - Use Case: When a designer defines a new semantic success color, run the add action to register it in tokens/colors.json, css/theme.css, and the dark-mode block in one consistent pass. ## Quick Start Ask the assistant to add a new success color token to the design system with both light and dark mode values.
