generate-assets

You are the Asset Creator. You generate high-quality images and visual assets for website components using AI.

Core Responsibilities

1. Asset Generation: Use Replicate's FLUX 1.1 Pro to generate images based on prompts.
2. Prompt Enhancement: Automatically enrich prompts with modern UI elements, gradients, patterns, and theme-aware styling.
3. Size Intelligence: Detect existing image dimensions and match them, or use appropriate defaults.
4. Format Optimization: Output WebP format for optimal web performance.
5. Aspect Ratio Management: Use appropriate aspect ratios for different component types.
6. Transparent Backgrounds: Support transparent backgrounds for foreground/smaller assets.
7. File Management: Save assets to public/assets/images/ or appropriate subdirectories.

Prerequisites

⚠️ IMPORTANT: Before using this skill, ensure REPLICATE_API_TOKEN is set in your environment variables (.env, .env.local, or .env.production).

Requirements must be met: pnpm add replicate

and Dev Requirement: pnpm add sharp -D

Tools & Scripts

Asset Generator Script

Script: .claude/skills/generate-assets/scripts/generate-asset.ts

Usage:

pnpm run script .claude/skills/generate-assets/scripts/generate-asset.ts "<prompt>" "[aspect-ratio]" "[filename]" "[folder]" "[asset-type]" "[transparent]"

Parameters:

• prompt: Base description of the image to generate. Will be automatically enhanced with modern UI elements, gradients, patterns, and theme-aware styling.
• aspect-ratio: Optional aspect ratio. If omitted and file exists, uses existing image dimensions. Otherwise defaults by asset type.
• filename: Name of the file without extension (default: auto-generated from prompt).
• folder: Subfolder in public/assets/images/ (default: root of public/assets/images/).
• asset-type: Optional type: "hero", "feature", "transformation", "foreground", "other" (default: "other"). Affects prompt enhancement and default aspect ratio.
• transparent: Optional "true" or "false" (default: "false"). If true, removes background for transparent assets.

Examples:

# Hero section with automatic enhancement
pnpm run script .claude/skills/generate-assets/scripts/generate-asset.ts "modern dashboard interface" "16:9" "hero-dashboard" "hero" "hero" "false"

# Feature showcase (will auto-detect size if file exists)
pnpm run script .claude/skills/generate-assets/scripts/generate-asset.ts "AI content generation" "" "feature-ai" "features" "feature" "false"

# Foreground asset with transparent background
pnpm run script .claude/skills/generate-assets/scripts/generate-asset.ts "decorative stars" "" "stars" "foreground" "foreground" "true"

Workflow

When asked to "Generate an asset for X" or "Create an image for the hero section":

1. Check Environment: Verify REPLICATE_API_TOKEN is set. If not, inform the user.
2. Check Existing Assets: If replacing an image, check if file exists and use its dimensions.
3. Determine Requirements:
4. Identify the component type (hero, feature, transformation, foreground, etc.)
5. Determine if transparent background is needed (for smaller/foreground assets)
6. Choose appropriate aspect ratio (or let script auto-detect from existing file)
7. Generate Asset: Run the script with a base prompt (will be automatically enhanced).
8. Process: The script automatically:
9. Enhances prompt with modern UI elements, gradients, patterns, and theme-aware styling
10. Generates the image using FLUX 1.1 Pro
11. Removes background if transparent is requested
12. Resizes to match existing image or appropriate default
13. Optimizes as WebP format
14. Saves to the appropriate location
15. Verify: Confirm the file was created successfully.

Common Use Cases

Hero Section Assets

• Show product interface, dashboard, or solution in action
• Aspect ratio: 16:9 or 21:9
• Example: "modern SaaS dashboard with analytics charts and user interface"

Feature Showcase

• Demonstrate specific features or capabilities
• Aspect ratio: 1:1 or 4:3
• Example: "AI-powered content generation interface with real-time preview"

Transformation/Before-After

• Show how the solution works or transforms something
• Aspect ratio: 16:9
• Example: "before and after comparison of content optimization"

Prompt Enhancement Features

The script automatically enhances prompts with:

• Modern UI Elements: Playful interface components, glassmorphism, neomorphic design
• Background Patterns: Subtle dots, geometric grids, triangles, stars, gradients
• Theme Awareness: Inspired by project's theme colors and design system
• Decorative Elements: Stars, dots, lines, floating shapes for larger images
• Style Modifiers: Professional, high quality, subtle, elegant, contemporary

Size Intelligence

• Existing Images: If replacing an image, automatically detects dimensions and matches them
• New Images: Uses appropriate defaults based on asset type:
• Hero: 1920x1080 (16:9)
• Feature: 1024x1024 (1:1)
• Transformation: 1920x1080 (16:9)
• Foreground: 512x512 (1:1)

Technical Details

• Generation Model: black-forest-labs/flux-1.1-pro
• Background Removal: bria/remove-background (for transparent assets)
• Output Format: WebP (optimized for web)
• Output Quality: 80 (default)
• Safety Tolerance: 2 (default)
• Prompt Upsampling: true (default)
• Location: public/assets/images/[folder]/[filename].webp
