Design System Extraction Prompt Kit

Reverse-engineer existing codebases into a structured, professional design system documentation.

by OpenPrompts_Bot
You are a senior design systems engineer conducting a forensic audit of an existing codebase. Your task is to extract every design decision embedded in the code — explicit or implicit. ## Project Context - **Framework:** [Next.js / React / etc.] - **Styling approach:** [Tailwind / CSS Modules / Styled Components / etc.] - **Component library:** [shadcn/ui / custom / MUI / etc.] - **Codebase location:** [path or "uploaded files"] ## Extraction Scope Analyze the entire codebase and extract the following into a structured JSON report: ### 1. Color System - Every color value used (hex, rgb, hsl, css variables, Tailwind classes) - Group by: primary, secondary, accent, neutral, semantic (success/warning/error/info) - Flag inconsistencies (e.g., 3 different grays used for borders) - Note opacity variations and dark mode mappings if present - Extract the actual CSS variable definitions and their fallback values ### 2. Typography - Font families (loaded fonts, fallback stacks, Google Fonts imports) - Font sizes (every unique size used, in px/rem/Tailwind classes) - Font weights used per font family - Line heights paired with each font size - Letter spacing values - Text styles as used combinations (e.g., "heading-large" = Inter 32px/700/1.2) - Responsive typography rules (mobile vs desktop sizes) ### 3. Spacing & Layout - Spacing scale (every margin/padding/gap value used) - Container widths and max-widths - Grid system (columns, gutters, breakpoints) - Breakpoint definitions - Z-index layers and their purpose - Border radius values ### 4. Components Inventory For each reusable component found: - Component name and file path - Props interface (TypeScript types if available) - Visual variants (size, color, state) - Internal spacing and sizing tokens used - Dependencies on other components - Usage count across the codebase (approximate) ### 5. Motion & Animation - Transition durations and timing functions - Animation keyframes - Hover/focus/active state transitions - Page transition patterns - Scroll-based animations (if any library like Framer Motion, GSAP is used) ### 6. Iconography & Assets - Icon system (Lucide, Heroicons, custom SVGs, etc.) - Icon sizes used - Favicon and logo variants ### 7. Inconsistencies Report - Duplicate values that should be tokens (e.g., `#1a1a1a` used 47 times but not a variable) - Conflicting patterns (e.g., some buttons use padding-based sizing, others use fixed height) - Missing states (components without hover/focus/disabled states) - Accessibility gaps (missing focus rings, insufficient color contrast) ## Output Format Return a single JSON object with this structure: { "colors": { "primary": [], "secondary": [], ... }, "typography": { "families": [], "scale": [], "styles": [] }, "spacing": { "scale": [], "containers": [], "breakpoints": [] }, "components": [ { "name": "", "path": "", "props": {}, "variants": [] } ], "motion": { "durations": [], "easings": [], "animations": [] }, "icons": { "system": "", "sizes": [], "count": 0 }, "inconsistencies": [ { "type": "", "description": "", "severity": "high|medium|low" } ] } Do NOT attempt to organize or improve anything yet. Do NOT suggest token names or restructuring. Just extract what exists, exactly as it is.
