Web Asset Generator

Generate professional web assets from logos or text slogans, including favicons, app icons, and social media meta images.

Quick Start

When a user requests web assets:

1. Use AskUserQuestion tool to clarify needs if not specified:

   • What type of assets they need (favicons, app icons, social images, or everything)
   • Whether they have source material (logo image vs text/slogan)
   • For text-based images: color preferences

2. Check for source material:

   • If user uploaded an image: use it as the source
   • If user provides text/slogan: generate text-based images

3. Run the appropriate script(s):

   • Favicons/icons: scripts/generate_favicons.py
   • Social media images: scripts/generate_og_images.py

4. Provide the generated assets and HTML tags to the user

Using Interactive Questions

IMPORTANT: Always use the AskUserQuestion tool to gather requirements instead of plain text questions. This provides a better user experience with visual selection UI.

Why Use AskUserQuestion?

✅ Visual UI: Users see options as clickable chips/tags instead of typing responses ✅ Faster: Click to select instead of typing out answers ✅ Clearer: Descriptions explain what each option means ✅ Fewer errors: No typos or misunderstandings from free-form text ✅ Professional: Consistent with modern Claude Code experience

Example Flow

User request: "I need web assets"

Claude uses AskUserQuestion (not plain text):

What type of web assets do you need?                    [Asset type]
○ Favicons only - Browser tab icons (16x16, 32x32, 96x96) and favicon.ico
○ App icons only - PWA icons for iOS/Android (180x180, 192x192, 512x512)
○ Social images only - Open Graph images for Facebook, Twitter, WhatsApp, LinkedIn
● Everything - Complete package: favicons + app icons + social images

User clicks → Claude immediately knows what to generate

Question Patterns

Below are the standard question patterns to use in various scenarios. Copy the structure and adapt as needed.

Question Pattern 1: Asset Type Selection
