prototype-craft skillA

prototype-craft is agent-read markdown (skill) from jnpiyush/agentx: Craft visually polished, production-quality HTML/CSS prototypes with modern styling, typography, color theory, and micro-interactions. Use when building UX deliverables that need visual polish beyond wireframes, implementing color systems, typography scales, elevation shadows, or smooth transitions for interactive prototypes..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Prototype Craft

Build beautiful, interactive HTML/CSS prototypes that look and feel like real products -- not wireframes.

## When to Use This Skill

- Building HTML/CSS prototypes that need production-quality visual polish
- Implementing color palettes, typography scales, and spacing systems
- Adding micro-interactions, transitions, and elevation shadows
- Crafting responsive layouts with modern CSS (Grid, Flexbox, custom properties)
- Polishing UX deliverables beyond skeletal wireframes

## Core Rules

1. **Visual polish first** -- prototypes MUST look production-quality, not skeletal
2. **Modern CSS** -- use CSS Grid, Flexbox, custom properties, clamp(), container queries
3. **Typography** -- use font pairing (max 2-3 families), proper scale (1.25-1.333 ratio), line-height 1.5-1.75
4. **Color system** -- define palette with CSS custom properties: primary, secondary, neutral, success, warning, error + tints/shades
5. **Spacing rhythm** -- use consistent 4px/8px base grid; spacing scale: 4, 8, 12, 16, 24, 32, 48, 64, 96
6. **Depth and shadow** -- layered box-shadows for elevation (sm, md, lg, xl); subtle borders for separation
