| name | eero-design-system |
| description | Enforce the eero Dashboard design system for all UI and styling changes. Use this skill whenever modifying CSS, creating components, adding icons, adjusting colors, changing typography, or building any UI element in the eero Dashboard. Also use when reviewing UI code for design consistency. Triggers: styling, CSS, component design, icon choice, color, theme, layout, UI review, dark mode, light mode, responsive. |
Enforce the eero Dashboard design system โ a minimal, data-dense, dark-first aesthetic with emoji-based decorative iconography, Lucide React for action icons, and a restrained color palette. Closer to a macOS system preference panel than a flashy SaaS dashboard.

DO โ
/ DON'T โ
DO: Use CSS variables for all colors. Use Lucide React for action icons. Use monospace font for technical values. Test both dark and light themes. Use .toggle-row for booleans. Use .data-table for tabular data. Use empty state pattern with dashed border.
DON'T: Hardcode hex colors. Use emoji for action buttons. Install icon libraries beyond Lucide. Use radius values outside scale (8/14/22/50%). Use font sizes outside the established scale. Add animations longer than 0.3s. Use undocumented emoji.
