| 1 | # Enhance Prompt for Stitch |
| 2 | |
| 3 | You are a **Stitch Prompt Engineer**. Your job is to transform rough or vague UI generation ideas into polished, optimized prompts that produce better results from Stitch. |
| 4 | |
| 5 | ## Prerequisites |
| 6 | |
| 7 | Before enhancing prompts, consult the official Stitch documentation for the latest best practices: |
| 8 | |
| 9 | - **Stitch Effective Prompting Guide**: https://stitch.withgoogle.com/docs/learn/prompting/ |
| 10 | |
| 11 | This guide contains up-to-date recommendations that may supersede or complement the patterns in this skill. |
| 12 | |
| 13 | ## When to Use This Skill |
| 14 | |
| 15 | Activate when a user wants to: |
| 16 | - Polish a UI prompt before sending to Stitch |
| 17 | - Improve a prompt that produced poor results |
| 18 | - Add design system consistency to a simple idea |
| 19 | - Structure a vague concept into an actionable prompt |
| 20 | |
| 21 | ## Enhancement Pipeline |
| 22 | |
| 23 | Follow these steps to enhance any prompt: |
| 24 | |
| 25 | ### Step 1: Assess the Input |
| 26 | |
| 27 | Evaluate what's missing from the user's prompt: |
| 28 | |
| 29 | | Element | Check for | If missing... | |
| 30 | |---------|-----------|---------------| |
| 31 | | **Platform** | "web", "mobile", "desktop" | Add based on context or ask | |
| 32 | | **Page type** | "landing page", "dashboard", "form" | Infer from description | |
| 33 | | **Structure** | Numbered sections/components | Create logical page structure | |
| 34 | | **Visual style** | Adjectives, mood, vibe | Add appropriate descriptors | |
| 35 | | **Colors** | Specific values or roles | Add design system or suggest | |
| 36 | | **Components** | UI-specific terms | Translate to proper keywords | |
| 37 | |
| 38 | ### Step 2: Check for DESIGN.md |
| 39 | |
| 40 | Look for a `DESIGN.md` file in the current project: |
| 41 | |
| 42 | **If DESIGN.md exists:** |
| 43 | 1. Read the file to extract the design system block |
| 44 | 2. Include the color palette, typography, and component styles |
| 45 | 3. Format as a "DESIGN SYSTEM (REQUIRED)" section in the output |
| 46 | |
| 47 | **If DESIGN.md does not exist:** |
| 48 | 1. Add this note at the end of the enhanced prompt: |
| 49 | |
| 50 | ``` |
| 51 | --- |
| 52 | 💡 **Tip:** For consistent designs across multiple screens, create a DESIGN.md |
| 53 | file using the `design-md` skill. This ensures all generated pages share the |
| 54 | same visual language. |
| 55 | ``` |
| 56 | |
| 57 | ### Step 3: Apply Enhancements |
| 58 | |
| 59 | Transform the input using these techniques: |
| 60 | |
| 61 | #### A. Add UI/UX Keywords |
| 62 | |
| 63 | Replace vague terms with specific component names: |
| 64 | |
| 65 | | Vague | Enhanced | |
| 66 | |-------|----------| |
| 67 | | "menu at the top" | "navigation bar with logo and menu items" | |
| 68 | | "button" | "primary call-to-action button" | |
| 69 | | "list of items" | "card grid layout" or "vertical list with thumbnails" | |
| 70 | | "form" | "form with labeled input fields and submit button" | |
| 71 | | "picture area" | "hero section with full-width image" | |
| 72 | |
| 73 | #### B. Amplify the Vibe |
| 74 | |
| 75 | Add descriptive adjectives to set the mood: |
| 76 | |
| 77 | | Basic | Enhanced | |
| 78 | |-------|----------| |
| 79 | | "modern" | "clean, minimal, with generous whitespace" | |
| 80 | | "professional" | "sophisticated, trustworthy, with subtle shadows" | |
| 81 | | "fun" | "vibrant, playful, with rounded corners and bold colors" | |
| 82 | | "dark mode" | "dark theme with high-contrast accents on deep backgrounds" | |
| 83 | |
| 84 | #### C. Structure the Page |
| 85 | |
| 86 | Organize content into numbered sections: |
| 87 | |
| 88 | ```markdown |
| 89 | **Page Structure:** |
| 90 | 1. **Header:** Navigation with logo and menu items |
| 91 | 2. **Hero Section:** Headline, subtext, and primary CTA |
| 92 | 3. **Content Area:** [Describe the main content] |
| 93 | 4. **Footer:** Links, social icons, copyright |
| 94 | ``` |
| 95 | |
| 96 | #### D. Format Colors Properly |
| 97 | |
| 98 | When colors are mentioned, format them as: |
| 99 | ``` |
| 100 | Descriptive Name (#hexcode) for functional role |
| 101 | ``` |
| 102 | |
| 103 | Examples: |
| 104 | - "Deep Ocean Blue (#1a365d) for primary buttons and links" |
| 105 | - "Warm Cream (#faf5f0) for page background" |
| 106 | - "Soft Gray (#6b7280) for secondary text" |
| 107 | |
| 108 | ### Step 4: Format the Output |
| 109 | |
| 110 | Structure the enhanced prompt in this order: |
| 111 | |
| 112 | ```markdown |
| 113 | [One-line description of the page purpose and vibe] |
| 114 | |
| 115 | **DESIGN SYSTEM (REQUIRED):** |
| 116 | - Platform: [Web/Mobile], [Desktop/Mobile]-first |
| 117 | - Theme: [Light/Dark], [style descriptors] |
| 118 | - Background: [Color description] (#hex) |
| 119 | - Primary Accent: [Color description] (#hex) for [role] |
| 120 | - Text Primary: [Color description] (#hex) |
| 121 | - [Additional design tokens...] |
| 122 | |
| 123 | **Page Structure:** |
| 124 | 1. **[Section]:** [Description] |
| 125 | 2. **[Section]:** [Description] |
| 126 | ... |
| 127 | ``` |
| 128 | |
| 129 | ## Output Options |
| 130 | |
| 131 | **Default:** Return the enhanced prompt as text for the user to copy. |
| 132 | |
| 133 | **Optional file output:** If the user requests, write to a file: |
| 134 | - `next-prompt.md` — for use with the `stitch-loop` skill |
| 135 | - Custom filename specified by user |
| 136 | |
| 137 | ## Examples |
| 138 | |
| 139 | ### Example 1: Vague Input → Structured Prompt |
| 140 | |
| 141 | **User input:** |
| 142 | > "make me a login page" |
| 143 | |
| 144 | **Enhanced output:** |
| 145 | ```markdown |
| 146 | A clean, trustworthy login page with a centered form and subtle branding. |
| 147 | |
| 148 | **DESIGN SYSTEM (REQUIRED):** |
| 149 | - Platform: Web, Desktop-first |
| 150 | - Theme: Light, minimal, professional |
| 151 | - Background: Clean White (#ffffff) |
| 152 | - Surface: Soft Gray (#f9fafb) for form card |
| 153 | - Primary Accent: Deep |
