OPTIK — Design Intelligence Engine

This skill replaces subjective design guidance with measurable intelligence. Every recommendation is backed by a scoring algorithm. Every suggestion comes with a metric. The AI doesn't learn opinions — it runs analysis.

Design Philosophy

Before writing any code, OPTIK requires three decisions:

1. Aesthetic commitment — Pick a direction and commit fully. Brutalist, editorial, maximalist, organic, industrial, retro-futuristic, luxury. Half-commitments produce the worst output. Bold minimalism beats timid maximalism every time.

1. Design score target — Set a minimum threshold (default: 75/100). Every decision gets evaluated against the five pillars: Typography, Color, Layout, Motion, Accessibility. If the score drops below target, the AI must fix before continuing.

1. Anti-pattern enforcement — OPTIK maintains a strict banlist. Violations are automatic failures.

The Five Pillars (Scoring)

1. Typography (25% of score)

Mathematical type scales only. No arbitrary font sizes.

Pick a ratio and compute:

• Minor second: 1.067
• Major second: 1.125
• Minor third: 1.200
• Major third: 1.250
• Perfect fourth: 1.333
• Augmented fourth: 1.414
• Perfect fifth: 1.500

Given a base size (16px) and ratio (1.250), the scale is: 16, 20, 25, 31.25, 39.06, 48.83, 61.04. Round to whole pixels. Use at minimum 5 distinct sizes for proper hierarchy depth.

Banned fonts (automatic -25 points): Inter, Roboto, Arial, Helvetica, system-ui, -apple-system, Open Sans, Lato, Montserrat, Poppins, Nunito, Space Grotesk, Raleway, Source Sans Pro

Required checks:

• Line measure: 45-75 characters per line. Compute from font-size and container width.
• Line height: body text 1.5-1.7, headings 1.1-1.3, captions 1.4-1.5
• Font weight usage: minimum 2 weights, maximum 4. Use weight to create hierarchy, not just size.
• Letter-spacing: headings may use -0.01 to -0.03em. All-caps text requires +0.05 to +0.15em.
• Font pairing: one display/serif + one body/sans or mono. Never two similar sans-serif fonts.

2. Color (25% of score)

Palette generation from a single brand color.

Given one hex value, generate:

• 50-950 shade scale (11 stops) using perceptual lightness interpolation
• Semantic tokens: surface, surface-elevated, text, text-secondary, text-muted, border, border-strong, accent, accent-hover, danger, success, warning
• Dark mode variants that maintain the same contrast ratios

Contrast requirements (WCAG 2.1):

• Body text: minimum 4.5:1 (AA)
• Large text (18px+ or 14px bold): minimum 3:1
• Interactive elements: minimum 3:1 against adjacent colors
• Target AAA (7:1) for body text when possible

Anti-patterns (automatic deductions):

• Purple gradient on white background: -30 points. The single most identifiable AI slop pattern.
• Pure black (#000000) for text: -5 points. Always tint dark colors with a hue.
• Gray-only palette: -10 points. Even monochrome designs need tinted grays.
• More than 15 unique color values without CSS custom properties: -15 points. Consolidate.
• Using opacity to create shades instead of actual computed colors: -5 points.

Required implementation:

• All colors as CSS custom properties (--color-name pattern)
• prefers-color-scheme media query if any dark surface exists
• Minimum 3, maximum 12 intentional colors (excluding shades of the same hue)

3. Layout (25% of score)

Spacing must be systematic, not arbitrary.

Given a base unit (default: 4px), the spacing scale is: 4, 8, 12, 16, 20, 24, 32, 40, 48, 64, 80, 96, 128

Every padding, margin, and gap value MUST come from this scale. Off-grid values are automatic deductions.

Grid requirements:

• Use CSS Grid or Flexbox. No float-based layouts.
• Set max-width on content containers (typically 1100-1280px for full-width, 680-720px for text content)
• Use the gap property instead of margin for spacing between grid/flex children
• Consistent gutter width across the page

Anti-patterns:

• Nested cards (cards inside cards): -20 points. Flatten the hierarchy.
• Spacing values not divisible by 4: -3 points each
• No media queries in layouts wider than 600px of content: -15 points
• No max-width constraint on text content: -10 points

Required checks:

• Nesting depth: maximum 4 levels of visual containment
• Density audit: sections should alternate between sparse and dense, not be uniformly one or the other
• Responsive verification: layout must work at 320px, 768px, and 1280px minimum

4. Motion (10% of score)

Motion must be purposeful, not decorative.

Start at 50/100 (neutral). Earn points for intentional motion. Lose points for violations.

Earning points:

• Transition declarations on interactive elements: +15
• Custom cubic-bezier easing (not just ease, ease-in-out): +10
• @keyframes for meaningful animations: +15
• Scroll-triggered reveals: +10
• Staggered animation delays for list items: +5
• transform-based animations (GPU-accelerated): +5

Losing points:

• Motion without prefers-reduced-motion fallback: -10
• Animations longer than 400ms without justification: -5
• Animating layout properties (width, height, top, left) instead of transform: -10
• More than 3 simultaneous animations competing for attention: -5

Required easing curves:

• Standard: cubic-bezier(0.4, 0, 0.2, 1)
• Decelerate (entering): cubic-bezier(0, 0, 0.2, 1)
• Accelerate (exiting): cubic-bezier(0.4, 0, 1, 1)
• Spring: cubic-bezier(0.34, 1.56, 0.64, 1)
• Smooth out: cubic-bezier(0.16, 1, 0.3, 1)

5. Accessibility (15% of score)

Accessibility is scored, not suggested.

Required (failure = deduction):

• :focus-visible styles on all interactive elements: -15 if missing
• Semantic HTML landmarks (header, main, nav, section, footer): -10 if missing
• No outline:none or outline:0 without replacement: -20 if found
• Skip link for keyboard navigation: +5 if present
• ARIA attributes where semantic HTML is insufficient: +5
• Touch targets minimum 44x44px for mobile: -10 if buttons/links are smaller
• prefers-reduced-motion query: -10 if motion exists without it
• prefers-color-scheme query: +10 if present
• Alt text on images: -5 per missing alt
• Color contrast meeting WCAG AA: already counted in Color pillar

Global Anti-Pattern Registry

These patterns are automatically flagged. Each one triggers specific deductions across the relevant pillar.

Token Generation

When generating design tokens, output in ALL of these formats simultaneously:

CSS Custom Properties:

:root {
  --color-surface: #0A0A0F;
  --color-text: #E8E6E3;
  --type-scale-base: 16px;
  --type-scale-ratio: 1.25;
  --space-unit: 4px;
}

Tailwind Config:

module.exports = {
  theme: {
    extend: {
      colors: { surface: '#0A0A0F', text: '#E8E6E3' },
      fontSize: { base: '16px', lg: '20px', xl: '25px' },
      spacing: { 1: '4px', 2: '8px', 3: '12px' }
    }
  }
}

W3C Design Tokens (JSON):

{
  "color": { "surface": { "$value": "#0A0A0F", "$type": "color" } },
  "typography": { "scale-base": { "$value": "16px", "$type": "dimension" } }
}

Execution Protocol

For every frontend task:

1. Assess — Determine aesthetic direction, target score, constraints
2. Generate — Build the design system (type scale, palette, spacing, tokens)
3. Implement — Write code following all five pillar requirements
4. Score — Run the internal scoring algorithm. If below target, iterate.
5. Verify — Check every anti-pattern. Fix any violations.

The AI must never ship code that scores below 65/100 without explicit user override. The target is 80+. Exceptional work scores 90+.

Remember

OPTIK is not about making things pretty. It's about making design decisions measurable, repeatable, and defensible. Every choice has a number attached. Every violation has a specific fix. The AI doesn't guess what good design looks like — it computes it.
