## What it does

The skill automates web asset generation through two Python scripts: `scripts/generate_favicons.py` and `scripts/generate_og_images.py`. It produces browser favicons, PWA icons, and Open Graph social cards. As source material, it accepts an uploaded logo, an emoji, or plain text slogans.

Interaction relies on the `AskUserQuestion` tool with clickable choices. The workflow handles brand colors: you can supply hex codes, auto-extract them from a logo, or use the default `#4F46E5` purple background. Once images are ready, the agent outputs HTML tags and can update framework files like `next.config.js` automatically.

Execution requires a local Python environment. Without an image, the script suggests emojis using the `--suggest` flag based on your project description.

# 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.
