# Logo Generator / Logo 生成器 ![Showcase](https://github.com/user-attachments/assets/c36c0e15-370c-4670-906e-36b829f9e7fa) [English](#english) | [中文](#中文) --- ## English Professional SVG logo generator with high-end showcase presentations. Generate 6+ design variants based on product characteristics, then create stunning showcase images with 12 professional background styles. ### About This skill was created to solve a common problem: generating professional logos quickly without sacrificing quality. Traditional logo design requires extensive back-and-forth with designers, while AI-generated logos often lack the refinement and presentation quality needed for real products. **Logo Generator** bridges this gap by: - Applying proven design principles (extreme simplicity, generous negative space, precise proportions) - Generating multiple variants to explore different directions - Creating production-ready showcase images with professional backgrounds - Providing both SVG (editable) and PNG (ready-to-use) formats Perfect for: - **Startups** needing a professional logo quickly - **Developers** building side projects - **Designers** exploring initial concepts - **Product teams** iterating on brand identity The skill leverages Gemini 3.1 Flash Image Preview (Nano Banana) to generate high-end showcase images that look like they came from a professional design studio. ### Features - **SVG Logo Generation**: Create geometric logos with dot matrix, line systems, and mixed compositions - **Design Variety**: Generate 6+ distinct variants per request with different pattern types - **Professional Showcase**: 12 curated background styles (void, frosted, fluid, spotlight, analog liquid, LED matrix, editorial, iridescent, morning, clinical, UI container, Swiss flat) - **Nano Banana Integration**: High-end showcase images using Gemini 3.1 Flash Image Preview - **Interactive Previews**: Beautiful HTML showcases with hover effects and smooth transitions ### Installation #### Method 1: Automatic Installation (Recommended) ```bash npx skills add https://github.com/op7418/logo-generator-skill.git ``` This will automatically install the skill to the correct directory. #### Method 2: Git Clone ```bash git clone https://github.com/op7418/logo-generator-skill.git ~/.claude/skills/logo-generator ``` #### Method 3: Manual Installation 1. Download this repository 2. Copy the `logo-generator` folder to your Claude Code skills directory: - **macOS/Linux**: `~/.claude/skills/` - **Windows**: `%USERPROFILE%\.claude\skills\` 3. Ensure the folder structure contains `SKILL.md` and `README.md` #### Post-Installation Setup After installation, set up the required dependencies: ```bash cd ~/.claude/skills/logo-generator pip install -r requirements.txt ``` Configure your Gemini API key: ```bash cp .env.example .env # Edit .env and add your GEMINI_API_KEY ``` Restart Claude Code and verify by typing `/logo-generator` in the conversation. ### Usage #### Basic Workflow 1. **Start a logo project**: ``` Generate a logo for my AI product called "DataFlow" ``` 2. **Provide context** (the AI will ask): - Industry/Category (e.g., AI, fintech, design tools) - Core Concept (e.g., connection, flow, security) - Design Preferences (minimal/complex, cold/warm) 3. **Review variants**: The AI generates 6+ SVG logo variants with design rationale 4. **Select and refine**: Choose your favorite, request adjustments 5. **Generate showcase**: Create professional presentation images with multiple background styles #### Example Commands ``` Create a logo for a blockchain security platform Generate 6 logo variants for "CloudSync" - a file sync tool Show me the logo in different background styles Export the logo as PNG at 2048x2048 ``` ### Workflow Phases **Phase 1: Information Gathering** Collect product name, industry, core concept, and design preferences **Phase 2: Pattern Matching & SVG Generation** - Generate 6+ distinct design variants - Create interactive HTML showcase - Explain design rationale for each variant **Phase 3: Iteration & Refinement** - Select favorite variants - Adjust parameters (size, spacing, rotation) - Combine elements from different variants **Phase 4: High-End Showcase Generation** - Export SVG to PNG (1024x1024px) - Select 4 showcase styles based on product type - Generate showcase images with Nano Banana - Create final presentation webpage **Phase 5: Delivery** - Interactive HTML showcase page - SVG files (editable vector format) - PNG exports (various sizes) - Showcase images (4 professional backgrounds) ### Background Styles #### Dark Styles (6) - **The Void** - Absolute black with silver micro noise (hardcore tech) - **Frosted Horizon** - Titanium gray with organic texture (premium products) - **Fluid Abyss** - Deep purple with fluid fusion (AI-native) - **Studio Spotlight** - Carbon gray with editorial lighting (magazine quality) - **Analog Liquid** - Metallic shimmer on solid color base (creative brands) - **LED Matrix** - Digital retro with glowing dots (cyberpunk) #### Light Styles (6) - **Editorial Paper** - Off-white with paper texture (humanistic brands) - **Iridescent Frost** - Silver-gray with holographic hints (tech hardware) - **Morning Aura** - Warm ivory with pastel colors (approachable AI) - **Clinical Studio** - Pure white with geometric shadows (algorithm-driven) - **UI Container** - Frosted glass container effect (SaaS platforms) - **Swiss Flat** - Pure solid color, zero effects (timeless authority) ### Design Principles 1. **Extreme Simplicity** - 1-2 core elements maximum 2. **Generous Negative Space** - At least 40-50% empty canvas 3. **Precise Proportions** - Line weights 2.5-4px, proper spacing 4. **Visual Tension** - Intentional asymmetry creates interest 5. **Restraint Over Decoration** - Every element must justify its existence 6. **Single Focal Point** - Clear visual hierarchy ### File Structure ``` logo-generator/ ├── SKILL.md # Skill definition and workflow ├── README.md # This file ├── requirements.txt # Python dependencies ├── .env.example # Environment variables template ├── scripts/ │ ├── svg_to_png.py # SVG to PNG converter │ └── generate_showcase.py # Showcase image generator ├── references/ │ ├── design_patterns.md # Comprehensive design guide │ ├── background_styles.md # Background style specifications │ └── webgl_backgrounds.md # WebGL dynamic backgrounds └── assets/ ├── showcase_template.html # HTML template for showcases └── background_library.html # Interactive WebGL backgrounds ``` ### Requirements - Python 3.8+ - Dependencies: `google-genai`, `python-dotenv`, `cairosvg`, `Pillow` - Gemini API key (for showcase generation) ### API Configuration #### Official Google Gemini API ```env GEMINI_API_KEY=your_api_key_here GEMINI_MODEL=gemini-3.1-flash-image-preview ``` #### Third-Party API Endpoint ```env GEMINI_API_KEY=your_api_key_here GEMINI_API_BASE_URL=https://api.example.com/v1 GEMINI_MODEL=gemini-3.1-flash-image-preview ``` ### License MIT License - feel free to use for personal or commercial projects ### Credits - Design patterns inspired by modern brand identity systems - Showcase styles curated from high-end design presentations - Powered by Gemini 3.1 Flash Image Preview (Nano Banana) ### Contributing Contributions welcome!
