rico-ui-ux-themes

UI/UX design optimization toolkit with 20 built-in themes and custom theme generation.

Workflow

[User Input] → [Read Current Project Code] → [Analyze 6 Issues] → [Select Mode] → [Confirm] → [Output]

CRITICAL EXECUTION RULES:

1. NEVER show welcome message or greeting
2. ALWAYS show selection menu A/B/C/D before execution
3. ALWAYS wait for user input after showing menu
4. ALWAYS confirm before making any changes
5. NEVER skip steps or auto-execute without user confirmation

Key Notes:

• Automatically read code from current working directory when triggered (e.g., "optimize this project/page/design"). No need to ask "which project".
• Language Rule: Detect from initial trigger (e.g., "rico 优化" = Chinese, "rico optimize" = English), then maintain consistent language throughout.
• Project mode detection: Only generate missing light/dark mode if explicitly requested; never force switch.
• Integration: Uses webReader (fetch URLs), Read/Write tools (code operations). All require confirmation.

4 Interaction Patterns

Triggers and Interaction Patterns

All commands use rico prefix. Supports 4 patterns:

Natural Language Support: e.g., "rico make it more vibrant" → Map to Full Flow or Direct Apply based on intent.

Selection Menu (Full Flow)

When user triggers "rico optimize", the workflow is:

[Read Current Project] → [Analyze 6 Dimensions] → [Show Menu A/B/C/D] → [User Selects] → [Confirm] → [Output]

IMPORTANT: Show the menu immediately after reading code. Do NOT ask "what do you want to do" or show welcome message.

Show Selection Menu

• B. Select from built-in themes (20 themes)
• C. Generate theme from industry reference
• D. Custom theme (URL or from project)

## 6-Dimension Analysis Framework

For detailed guidelines, see `references/docs/`.

| Dimension | Check Points | Reference |
|-----------|--------------|-----------|
| **1. Color** | Contrast (WCAG AA 4.5:1), brand usage ≤10%, saturation, light/dark mode | color.md |
| **2. Typography** | Hierarchy, line-height, font weight, alignment | typography.md |
| **3. Spacing** | Grid system (4pt), whitespace, alignment | layout.md |
| **4. Border-radius** | Consistency, unified style | component.md |
| **5. Shadow** | Hierarchy, meaning, avoid generic | component.md |
| **6. Interaction** | 8 states (default/hover/focus/active/disabled/loading/error/success), feedback | motion.md |

### Quick Analysis Checklist

| Issue Type | Common Problems |
|------------|-----------------|
| Color | Low contrast, color abuse, washout on colored bg |
| Typography | Inconsistent sizes, line-height, mixed fonts |
| Spacing | No grid, cramped, misaligned |
| Border-radius | Inconsistent sizes, mixed styles |
| Shadow | Too heavy, meaningless, generic |
| Interaction | Missing states, weak feedback |

For complete audit methodology, see `references/docs/polish.md`.

## Design Anti-Patterns

Based on Impeccable design principles:

### Visual
- **DON'T** use gray text on colored backgrounds → use tinted shade
- **DON'T** use pure black (#000) or white (#fff) → always tint
- **DON'T** use "AI color palette" (cyan-on-dark, purple gradients)
- **DON'T** overuse brand colors → accent ≤10%

### Layout
- **DON'T** wrap everything in cards
- **DON'T** nest cards inside cards
- **DON'T** center everything → asymmetry feels more designed

### Typography
- **DON'T** use overused fonts (Inter, Roboto, Arial)
- **DON'T** use too many similar font sizes → muddy hierarchy

### Motion
- **DON'T** use bounce easing → feels dated
- **DON'T** animate layout properties → use transform only
- **DON'T** ignore prefers-reduced-motion

### The AI Slop Test

If someone says "AI made this" and it's immediately obvious → that's the problem.
Distinctive design makes people ask "how was this made?" not "which AI?"

## Theme Generation

### Workflow

[URL] → [webReader fetch] → [Extract design] → [Generate 14-chapter doc] → [Save]

### Reference Documents

Use these docs from `references/docs/` when generating themes:

- **themes-guide.md** - 14-chapter template for theme structure
- **color.md** - Color system guidelines
- **typography.md** - Typography rules
- **layout.md** - Spacing/grid system
- **component.md** - Component design standards
- **motion.md** - Animation principles
- **polish.md** - 6-dimension audit framework

### Generated Theme Structure (14 Chapters)

Every generated theme includes:

1. **Design Philosophy** (设计核心理念)
   - Brand concept / Design philosophy
   - Core keywords (3-5)
   - Why this design?

2. **Color System + Usage Guidelines** (颜色系统 + 使用原则)
   - Primary, background, text, accent colors
   - When to use each color
   - Usage proportion rules
   - Common mistakes

3. **Interaction Philosophy** (交互理念)
   - Animation principles
   - Feedback mechanisms
   - Transition timing

4. **Layout Principles** (布局原则)
   - Spacing strategy (grid system)
   - Whitespace principles
   - Content max-width

5. **Component Design Decisions** (组件设计决策)
   - Why this height/radius/color?
   - Design rationale

6. **Application Scenarios** (应用场景)
   - Suitable project types
   - Adjustments for different scenarios

7. **Common Mistakes** (避免的误区)
   - 5+ common errors
   - Negative checklist

Plus 7 more chapters covering typography, spacing, shadows, components, animations, and use cases.


### Save Location
- Project: `references/styles/[theme-name].md`
- Global: `~/.rico/themes/[theme-name].md`

## Theme Application Workflow

User Input: rico apply [theme-name] ↓ ┌──────────────────────────────────────────┐ │ 1. Load theme from references/styles/ │ │ 2. Detect theme mode (light/dark) │ │ 3. Switch project to theme's mode │ ← Key: Apply dark → switch to dark │ 4. Analyze code: 6-dimension check │ │ 5. Apply theme colors, spacing, etc. │ │ 6. Generate optimized code │ │ 7. Explain key decisions │ └──────────────────────────────────────────┘

**Theme Mode Application Rule:**
| Project Mode | Theme Mode | Action |
|--------------|------------|--------|
| Single (light/dark) | Dual (both) | Use only project's existing mode colors |
| Single (light/dark) | Single | Apply theme's defined mode |
| Dual (both) | Any | Apply theme's defined mode |

**Never force switch mode.** Theme's dual-mode is "supported", not "required".

### Analysis Dimensions

AI checks these design dimensions:

1. **Color** - Contrast ratios, saturation, brand color usage, light/dark theme support, tinted neutrals
2. **Typography** - Font size, line-height, weight, font family
3. **Spacing** - Grid system, whitespace, compactness
4. **Border Radius** - Size consistency, style unity
5. **Shadow** - Weight, consistency, meaningful
6. **Interaction** - Button/link states, animations, feedback
7. **Icons** - All original icons preserved (SVG, icon fonts, images)
8. **Gradients** - All gradient backgrounds preserved

## Design Reference Files

Located in `references/docs/`:

- **color.md** - Color design reference
- **component.md** - Component design reference

### Mode Detection

| Project Mode | Theme Support | Action |
|--------------|---------------|--------|
| Dual-mode | Both defined | Generate CSS variables for both |
| Light-only | Any | Apply light mode only (don't auto-add dark) |
| Dark-only | Any | Apply dark mode only (don't auto-add light) |

**Note:** Only generate missing mode if user explicitly requests it. Don't auto-generate dark/light mode unless asked.

### Key Decisions to Explain

- Theme mode strategy
- Icon handling (preserve vs adapt)
- Gradient handling (preserve vs adapt)
- Impeccable principles applied

| Stack | Support | Handling |
|-------|---------|----------|
| React | Full | JSX, styled-components, CSS Modules |
| Vue | Full | Vue SFC, scoped styles |
| Angular | Full | Component styles |
| HTML/CSS | Full | CSS variables |
| Sass/SCSS | Full | Variables, mixins |
| Tailwind | Full | Theme config |

## Best Practices

### Choosing Theme

| Project Type | Recommended Themes |

## Quick Examples

### User: rico optimize this website

[Read code] → [Analyze 6 dimensions] → [Show menu A/B/C/D] → [User selects] → [Confirm] → [Generate]

### User: rico use Claude style

[Load claude.md] → [Show style preview] → [Confirm] → [Apply to code]

### User: rico create theme: stripe.com

## Theme Naming Convention

All themes follow **"Style + Color/Feature"** naming.

This naming convention helps users quickly understand each theme's core characteristics and applicable scenarios.

---

## Integration

This skill integrates with:

- **webReader tool** - Fetch target pages for theme generation
- **Read tool** - Read existing code files
- **Write/Edit tools** - Generate optimized code

All operations require user confirmation before execution.
