A Swiss International Style design system for AI agents. Grotesque typography, rigorous grid, generous whitespace, restrained color — expressed through Tailwind CSS.

swiss.ziki.boo

npx skills add zeke/swiss-design-skill

Or manually copy the skill directory:

gh repo clone zeke/swiss-design-skill
cp -r swiss-design-skill/swiss-design ~/.config/opencode/skills/

Once installed, tell your agent to apply it:

• "Apply the swiss-design skill to this page"
• "Clean up this UI using swiss design principles"
• "Make this look great — use the Swiss style"

The agent will apply IBM Plex Sans typography, the stone color palette, opacity-based hierarchy, a 12-column grid, and generous whitespace.

• Grid first. 12-column, 8px base unit
• Whitespace is structure. Sections get py-24 minimum
• Opacity, not hue, creates hierarchy. text-stone-900/70, never text-stone-500
• One accent. Swiss red (#C8102E) by default; swap to cobalt, golden, or forest per project
• Narrow columns. Body text never exceeds max-w-[60ch]
• Light and dark mode via prefers-color-scheme
