## 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
- **layout.md** - Layout design reference
- **motion.md** - Animation design reference
- **polish.md** - Design audit reference
- **themes-guide.md** - Theme generation prompt template
- **typography.md** - Typography 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
