Less Is More UI

"Good design is as little design as possible." — Dieter Rams

A specialized design skill for AI agents to generate calm, high-quality, and functional web interfaces.

The Problem

Most AI-generated UIs suffer from "visual noise": excessive shadows, generic gradients, and cluttered layouts. They often lack a clear typographic hierarchy and rational structure because LLMs tend to default to "over-designed" or generic components.

The Solution

less-is-more-ui provides a set of modernist constraints that force the agent to prioritize content and function. It transforms the agent from a generic coder into a senior designer with a Miesian perspective, focusing on:

• Rational Layouts: Using grid systems and generous whitespace instead of decorative containers.
• Typography-First Hierarchy: Letting text carry the weight of the interface.
• Subtle Palettes: Using color to support, not dominate.
• Systematic Spacing: A predefined variable-based scale for consistent rhythm.

How to Use with AI Agents

Once activated, you can direct your agent with high-level design intent. The agent will use the bundled resources (principles.md, references/components.md, etc.) to make informed decisions.

Example Prompts:

• "Refactor this dashboard following the Less Is More manifesto."
• "Simplify this landing page. Use only the scale variables and remove all decorative elements."
• "Build a contact form using the 'Honest Materials' precept (semantic HTML only)."

Philosophy

2. Form follows function. (Logic over decoration)
3. Less but better. (Instinctive simplicity)
