Output comprehensive PDF documents that serve as the single source of truth for design and development teams. ## Workflow Decision Tree When a user requests a style guide, follow this decision tree: 1. **Gather Information** - If user provides URL → Use web_fetch to analyze the website - If user provides screenshots/images → Analyze visual elements - If user provides existing documentation → Extract and structure information - If user provides minimal information → Ask clarifying questions about brand, goals, and requirements 2. **Extract Design Elements** - Colors (primary, secondary, accent, text, background, success, warning, error) - Typography (fonts, weights, sizes, line heights) - Logo usage guidelines - Iconography style - Imagery preferences - UI component patterns - Layout and spacing systems - Accessibility requirements 3. **Structure Content** - Follow the standard template structure (see Template Structure section) - Organize extracted information into appropriate sections - Add mission/vision if provided or inferred - Document design principles - Create component specifications 4. **Generate PDF** - Use the PDF skill to create a professional document - Apply consistent formatting and typography - Include tables for color palettes, typography specs, and component states - Ensure accessibility with proper contrast ratios - Add version number and last updated date ## Standard Template Structure Every style guide should follow this professional structure (based on industry best practices): ### 1.0 Introduction - Version number and last updated date - Purpose and scope statement - Target audience (design and development teams) ### 1.1 Mission & Vision - Company mission statement - Company vision statement - Strategic positioning ### 1.2 Design Principles - 4-6 core principles that guide design decisions - Each principle with name and description - Examples: "Clarity Above All", "Empowerment Through Simplicity", "Consistency Builds Trust", "Human-Centered" ### 2.0 Brand Identity #### 2.1 Logo Usage - Primary logo specifications - Clear space requirements - Incorrect usage examples - Minimum size requirements - Color variations (full color, black, white) #### 2.2 Color Palette - Organized table with Role, Color Name, HEX, and RGB values - Primary colors (1-2) - Secondary colors (1-3) - Accent colors - Text colors - Background colors - System colors (Success, Warning, Error) - Accessibility notes for each color combination #### 2.3 Typography - Heading font specifications (H1, H2, H3) - Body text specifications - Caption/small text specifications - Font families, weights, sizes, and line heights in tabular format - Web font loading considerations - Fallback fonts #### 2.4 Iconography - Icon style guidelines (outlined, filled, line weight) - Grid system specifications - Size variants - Usage examples - Link to icon library #### 2.5 Imagery - Photography style guidelines - Illustration style guidelines - Image treatment specifications - Do's and don'ts - Quality requirements ### 3.0 Content Style Guide #### 3.1 Voice and Tone - Voice characteristics (consistent attributes) - Tone variations (how voice adapts to context) - Examples for different scenarios #### 3.2 Grammar and Mechanics - Punctuation rules - Capitalization standards - Voice preference (active/passive) - Number formatting - Date and time formatting ### 4.0 UI Components #### 4.1 Buttons - State variants (Primary, Secondary, Tertiary, Disabled) - Size variants - Usage guidelines - Code snippets (HTML/CSS) - Accessibility requirements #### 4.2 Forms - Input field specifications - Label positioning - Validation states - Required field indicators - Error message styling - Help text formatting #### 4.3 [Additional Components as needed] - Cards - Modals - Navigation - Tables - Alerts/Notifications - Tooltips - Badges - Progress indicators ### 5.0 Layout & Grid - Grid system specifications (columns, gutters) - Responsive breakpoints - Spacing scale (base unit and multipliers) - Container widths - Margin and padding conventions ### 6.0 Accessibility (A11y) - WCAG compliance level (2.1 AA standard) - Color contrast requirements - Alt text guidelines - Keyboard navigation standards - Screen reader considerations - Focus indicators ### 7.0 Resources - Links to design files (Figma, Sketch, Adobe XD) - Icon library location - Illustration library location - Font files repository - Code repository - Additional documentation ### 8.0 Changelog - Version history with dates - Changes summary for each version ## Information Extraction Process When analyzing provided materials, extract the following systematically: ### From URLs/Websites: 1. Fetch the website using web_fetch 2. Analyze HTML/CSS for: - Color values (background-color, color properties) - Font families and typography (font-family, font-size, font-weight) - Spacing patterns (margin, padding values) - Component structures 3. Take note of: - Visual hierarchy - Button styles and states - Form element treatments - Navigation patterns - Responsive behavior (if observable) ### From Screenshots/Images: 1. Identify color palette using visual analysis 2. Determine typography hierarchy 3. Note spacing and layout patterns 4. Identify UI component variants 5. Observe design principles in practice ### From Existing Documentation: 1. Extract mission/vision statements 2. Gather existing brand guidelines 3. Collect color specifications 4. Document current typography standards 5. Note any existing component libraries ## Creating Professional Tables Use well-formatted tables for specifications. Example formats: **Color Palette Table:** ``` | Role | Color | HEX | RGB | |------------|-------------|---------|---------------| | Primary | Brand Blue | #378DFF | 55, 141, 255 | | Secondary | Light Blue | #A5CAFF | 165, 202, 255 | ``` **Typography Table:** ``` | Element | Font Family | Weight | Size (px) | Line Height | |---------|-------------|---------|-----------|-------------| | H1 | Inter | Bold | 48 | 1.2 | | H2 | Inter | Bold | 36 | 1.3 | | Body | Inter | Regular | 16 | 1.5 | ``` **Button States Table:** ``` | State | Appearance | Usage | |-----------|-------------------------|--------------------------------| | Primary | Solid fill, primary | Main call to action on a page | | Secondary | Outline, primary color | Secondary actions | | Tertiary | Text only | Less important actions | ``` ## PDF Generation Best Practices 1. **Professional Formatting:** - Use consistent heading hierarchy - Apply proper spacing between sections - Utilize tables for structured data - Include visual examples where possible 2. **Typography:** - Use professional fonts (Inter, Roboto, or system fonts) - Maintain consistent sizing hierarchy - Ensure sufficient line height for readability 3. **Color Usage:** - Show color swatches with hex codes - Ensure sufficient contrast for accessibility - Document color roles clearly 4. **Organization:** - Number sections clearly (1.0, 1.1, 2.0, etc.) - Include table of contents for longer guides - Use page breaks appropriately - Add page numbers 5. **Accessibility:** - Ensure document is screen-reader friendly - Use proper heading structure - Include alt text for images - Maintain minimum font size of 12pt ## Handling Incomplete Information When information is missing or unclear: 1. **Make Reasonable Inferences:** - Extract colors from provided screenshots - Infer typography from website analysis - Estimate spacing based on visual patterns 2. **Use Placeholders:** - "[Insert company mission statement]" for unknown content - "[Link to design files]" for unavailable resources - "Version 1.0" and current date as defaults 3. **Ask Clarifying Questions:** - "What is your company's mission statement?" - "Do you have existing brand colors or should I extract them from the website?" - "Are there specific accessibility requirements beyond WCAG 2.1 AA?" 4. **Provide Templates:** - Include example text for sections that need user input - Show format for content they should provide - Give guidance on what information would be ideal ## Example User Interactions **Example 1: URL-Based Request** User: "Create a style guide for my website at example.com" Process: 1. Fetch website with web_fetch 2. Analyze HTML/CSS for design system 3. Extract colors, fonts, spacing 4. Structure into standard template 5. Generate professional PDF 6.
