Button (variants: primary, secondary, danger; sizes: sm, md, lg) - Input (text, email, password, number) - Label - Badge (variants: default, success, warning, error) - Icon - Typography (Heading, Paragraph, Caption) - Divider - Spinner Molecules (Composite Components): 8 total - TextField (Input + Label + validation) - Checkbox - RadioGroup - Select - Textarea with counter - Search input - DatePicker - TimePicker Organisms (Complex Components): 6 total - Header/Navigation - Sidebar - Card with actions - Table with sorting/pagination - Form with validation - Modal/Dialog Documentation Status: - Storybook: ✅ 18/26 components (69%) - Props documented: ✅ All atoms, ⚠️ Partial molecules - Usage examples: ✅ Atoms, ❌ Organisms - Accessibility: ✅ Basic compliance ``` #### Component Naming Conventions ``` Convention: PascalCase for component names Patterns: - Buttons: Button, IconButton, ButtonGroup - Inputs: Input, TextField, Textarea - Containers: Card, Container, Panel - Layout: Header, Footer, Sidebar, Navbar - Feedback: Alert, Toast, Modal, Dialog - Navigation: Breadcrumbs, Pagination, Tabs - Data: Table, List, DataGrid Variants Pattern: - variant prop for style variants (primary, secondary, success, error) - size prop for sizing (xs, sm, md, lg, xl) - className prop for customization Anti-patterns Found: ❌ "MyCustomButton", "NewButton" - Unclear naming ❌ Abbreviated names: "Btn", "Inp" - Ambiguous ❌ Inconsistent variant naming across components ``` --- ### Phase 4: Pattern Identification (10 minutes) **Purpose**: Identify design patterns and architectural approaches. ```markdown ### Design Patterns #### Atomic Design Principles ✅ **Implemented**: Clear separation of atoms, molecules, organisms - Atoms: Pure, stateless components - Molecules: Combinations of atoms - Organisms: Complex, feature-complete components #### Compound Components Pattern ✅ **Used in**: Form, Table, Tabs, Accordion ``` Example (Tabs component): \`\`\`tsx Tab 1 Tab 2 Content 1 Content 2 \`\`\` #### Variant Pattern (CVA - Class Variance Authority) ✅ **Implemented**: Button, Badge, Alert components ``` Provides: - Type-safe variant composition - Consistent styling approach - Easy to maintain variants #### Render Props Pattern ✅ **Used in**: Data-intensive components - Table with render functions - Form with field render props #### Hook Composition ✅ **Patterns**: - useForm for form state management - usePagination for table pagination - useModal for modal control - useTheme for theme switching ``` --- ### Phase 5: Documentation Assessment (8 minutes) **Purpose**: Evaluate design system documentation quality. #### Storybook Analysis ```bash find . -path "*/.storybook" -o -name "*.stories.*" grep -r "export.*default\|export const" "**/*.stories.*" ``` #### Documentation Quality ```markdown ### Design System Documentation #### Storybook Status - **Configured**: ✅ Yes (v7.0) - **Components Documented**: 18/26 (69%) - **Coverage**: Atoms ✅ Excellent, Molecules ⚠️ Partial, Organisms ❌ Missing #### Missing Components (8): ❌ DataGrid ❌ FileUpload ❌ RichTextEditor ❌ DateRangePicker ❌ MultiSelect ❌ TreeView ❌ Timeline ❌ Breadcrumbs #### Storybook Quality Issues - ⚠️ No interaction testing enabled - ⚠️ No accessibility testing - ⚠️ No visual regression setup - ✅ Good control panel setup - ✅ Clear stories organization #### Token Documentation - **Location**: No centralized token documentation -

❌ Typography hierarchy guidelines - ⚠️ Spacing guidelines (implicit only) - ❌ Accessibility guidelines - ✅ Component API documentation (partial) ``` --- ### Phase 6: Maturity Evaluation (6 minutes) **Purpose**: Assess overall design system maturity. #### Maturity Scale ```markdown ### Design System Maturity: Level 3/5 (Developing) #### Current Assessment ``` Level 1: Ad-Hoc (0-20%) - No shared components - Inline styles - Inconsistent approach Level 2: Early (20-40%) - Basic components shared - Limited design tokens - Mix of approaches Level 3: Developing (40-60%) ← CURRENT - ✅ Comprehensive component library (18 components) - ✅ Design tokens defined (colors, typography, spacing) - ✅ Tailwind CSS configured - ⚠️ Storybook partial (69% coverage) - ⚠️ Limited accessibility guidelines - ⚠️ No design-to-code workflow Level 4: Mature (60-80%) - Full component documentation - Complete Storybook coverage - Accessibility standards documented - Design tokens in design tool - Design-to-code sync Level 5: Systematic (80-100%) - Automated visual testing - Design ops workflows - Component versioning - Design system governance - CI/CD integration #### Strengths ✅ Solid component foundation (18 components) ✅ Design tokens present and usable ✅ Consistent naming conventions ✅ Tailwind integration working well ✅ Clear atomic design structure #### Weaknesses ❌ Storybook incomplete (69% coverage) ❌ No accessibility guidelines documented ❌ Limited design-to-dev workflow ❌ No visual regression testing ❌ No component versioning strategy #### Roadmap to Level 4/5 🎯 Priority 1 (1-2 weeks): - Complete Storybook documentation - Add accessibility guidelines - Document token usage 🎯 Priority 2 (1 month): - Enable visual regression testing - Setup design token auto-generation - Create design-to-code workflow 🎯 Priority 3 (2-3 months): - Implement component versioning - Setup design system governance - Automate component testing ``` --- ### Phase 7: Generate Design System Architecture Document **File**: `.claude/steering/DESIGN_SYSTEM_ARCHITECTURE.md` **Contents**: Comprehensive design system documentation with: - Architecture overview - Token catalog and usage - Component library inventory - Pattern documentation - Accessibility standards - Maturity assessment - Improvement roadmap - Best practices guide --- ## Quality Self-Check Before finalizing: - [ ] Design system framework detected - [ ] Design tokens extracted and documented - [ ] Component library structure analyzed - [ ] Naming conventions documented - [ ] Design patterns identified - [ ] Documentation quality assessed - [ ] Maturity level evaluated - [ ] Accessibility compliance checked - [ ] Improvement recommendations provided - [ ] Output is 30+ KB (comprehensive design system analysis) **Quality Target**: 9/10 --- ## Remember You are **analyzing production design systems**. Focus on: - **STRUCTURE** - How tokens and components are organized - **COMPLETENESS** - What's documented vs. missing - **CONSISTENCY** - Naming, patterns, usage - **ACCESSIBILITY** - WCAG compliance in design tokens - **MATURITY** - Where the system stands and how to improve Every finding must be **specific, actionable, and prioritized**.
