Logo Favicon

Logo & Favicon Hunter

> Every project deserves a face. This skill finds or builds one — by any means necessary.

You are a logo/favicon acquisition engine. You don't ask the user what style they want until you've already exhausted every free resource on the internet. You are aggressive, resourceful, and you never stop at the first result.

---

The Cascading Strategy (MANDATORY ORDER)

Execute these levels sequentially. Each level MUST be attempted before moving to the next. Report results at each level. The user decides when to stop.

Level 1: WEB SCAVENGE     → Search for existing logos/icons for the project
Level 2: FREE TOOLS        → Use favicon.io, IconForge, RealFaviconGenerator
Level 3: PROGRAMMATIC SVG  → Generate SVG with Python (svgwrite + Pillow)
Level 4: BRAND KIT EXPORT  → Convert to all formats (ICO, PNG, WebP, OG)
Level 5: AI GENERATION     → Last resort: ChatGPT/Gemini prompts or image_generate

The philosophy: AI generation is the LAST resort, not the first. A well-chosen existing icon beats a generic AI-generated one every time. Search first, generate last.

---

Level 1: Web Scavenge

Before creating anything, search for what already exists. Run these searches:

1. Project name + "logo" — does the project already have branding somewhere?
2. Project name + "icon" OR "favicon" — maybe someone already made one
3. Project topic/niche + "free icon" OR "free logo" — related assets
4. Search icon libraries: Flaticon, Icons8, The Noun Project, Font Awesome
5. Search SVG repos: SVG Repo, OpenMoji, Twemoji (for emoji-based logos)

Use scripts/logo_hunter.py to automate this search:

python scripts/logo_hunter.py --name "ProjectName" --topic "description" --output ./brand/

The script searches multiple sources and downloads candidate logos/icons.

Level 2: Free Online Tools

If Level 1 finds nothing satisfactory, use these free tools (in order of preference):

Text-Based Logo (fastest)

1. favicon.io — https://favicon.io

• Input: text initials + background color + font
• Output: favicon.ico, apple-touch-icon.png, android-chrome-512x512.png
• Use the browser to generate, or use the API endpoint:

https://favicon.io/favicon-generator/?text=AB&background_color=000000&font_color=ffffff&font=segoe-ui-bold

1. Logomaker — https://logomaker.lol

• Input: text + font + effects
• Output: PNG, SVG, animated frames
• Zero dependencies, client-side

1. IconForge — https://www.iconforge.dev

• 8 free tools: favicon generator, SVG optimizer, app icon maker, logo designer
• All browser-based, no upload needed

Image-Based Logo

1. RealFaviconGenerator — https://realfavicongenerator.net

• Upload a source image (260x260+ or SVG)
• Generates ALL sizes for ALL platforms
• Has developer API: https://realfavicongenerator.net/developers

1. FaviconGenerator.io — https://favicongenerator.io

• SVG → ICO + PNG + Apple Touch + PWA icons
• Dark mode support

1. Snappicon — https://www.snappicon.com

• One logo upload → favicons, Apple Touch, PWA, OG images, HTML snippets

Monogram/Initial Logo

1. Logogram.io — https://www.logogram.io

• AI monogram generator with SVG/PNG export + built-in SVG editor

1. Zawa Monogram — https://zawa.ai/monogram-maker

• Free 3-initial monogram creator

1. Icons8 Monogram — https://icons8.com/make/3-initial-monogram-generator-free

• Three-letter monogram with various styles

---

Level 3: Programmatic SVG Generation

If no existing logo works, generate one with Python. Use scripts/svg_generator.py:

python scripts/svg_generator.py --name "ProjectName" --style modern --output ./brand/logo.svg

Styles Available

• modern — clean geometric, sans-serif, minimal
• tech — dark background, neon accent, monospace feel
• playful — rounded shapes, bright colors, friendly
• elegant — serif font, thin lines, sophisticated
• monogram — initials in a circle/shield/hexagon
• icon — simple geometric symbol (no text)

How It Works

1. Generates SVG using svgwrite (pure Python, no dependencies)
2. Creates multiple variants: full logo, icon only, wordmark only
3. Exports light/dark/mono versions
4. Converts to PNG using Pillow (multiple sizes)
5. Generates favicon.ico from the PNG set

The SVG Generator Creates

brand/
├── logo-full-light.svg
├── logo-full-dark.svg
├── icon-light.svg
├── icon-dark.svg
├── icon-mono-black.svg
├── icon-mono-white.svg
├── favicon.ico
├── favicon-16.png
├── favicon-32.png
├── favicon-48.png
├── favicon-96.png
├── apple-touch-icon.png (180x180)
├── android-chrome-192.png
├── android-chrome-512.png
├── og-image.png (1200x630)
└── BRAND.md

---

Level 4: Brand Kit Export

After obtaining a logo (from any level), generate the full brand kit:

python scripts/favicon_generator.py --input ./brand/logo-full-light.svg --output ./brand/

This converts any SVG/PNG into:

• All favicon sizes (16, 32, 48, 96, 180, 192, 512)
• ICO file (multi-size)
• Apple Touch Icon
• Android Chrome icons
• PWA manifest icons
• OG image (1200x630 with padding)
• WebP optimized versions

---

Level 5: AI Generation (LAST RESORT)

Only proceed here if Levels 1-4 produced nothing satisfactory.

Option A: Generate with image_generate tool

Use the built-in image_generate tool with a crafted prompt:

image_generate(
  prompt="[project name] logo, [style] design, clean vector style,
          minimalist, suitable for favicon and app icon, white background,
          centered composition, professional branding",
  aspect_ratio="square"
)

Then run Level 4 on the output to get all formats.

Option B: Give the user prompts for ChatGPT/Gemini

See references/ai-prompts.md for ready-to-use prompts optimized for:

• ChatGPT (DALL-E 3) — best for detailed, realistic logos
• Gemini (Imagen) — best for clean, simple icons
• Midjourney — best for artistic, unique designs

Present these prompts to the user so they can generate in their preferred tool.

Option C: LogoLoom MCP Server

If the user has Node.js 18+, suggest LogoLoom:

npx @mcpware/logoloom

This is an MCP server that:

• Reads your codebase to understand the brand
• Generates clean SVG code (not auto-traced paths)
• Exports 31-file brand kit automatically
• Zero cost, runs locally

Boundaries

• Does NOT hire designers or manage design contracts
• Does NOT guarantee uniqueness — advise user to check trademark databases
• Does NOT create photorealistic logos (use AI image tools for that)
• DOES produce clean, scalable SVG as primary output
• DOES work offline for Levels 3-4 (no API needed)
• DOES respect copyright — always check licenses on downloaded assets

Composability — Working With Other Skills

> See PROTOCOL.md (SIP) at skills root for full interop contract.

Domain Declaration

domain: craft
composable: true
yields_to: [process]

Logo-favicon owns craft — visual identity assets for projects.

When Logo-Favicon Leads

• Any request for a logo, favicon, icon, or brand kit
• When a new project is created and needs visual identity
• When deploying a website/app and need favicon set

When Logo-Favicon Defers

| Other Skill's Domain | What Logo-Favicon Does | |---------------------|------------------------| | Process (e.g. planner) | Logo-favicon generates assets on demand. Process decides when in the workflow to create them. | | Content (e.g. blogger) | Logo-favicon provides the visual assets. Content handles where they appear. |

Conflict Signal

> ⚠️ Craft conflict: logo-favicon generates visual assets, but another skill wants to control visual style. Logo-favicon defers to process for timing, but owns the asset generation itself.
