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:

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
Check for source material:
- If user uploaded an image: use it as the source
- If user provides text/slogan: generate text-based images
Run the appropriate script(s):
- Favicons/icons: scripts/generate_favicons.py
- Social media images: scripts/generate_og_images.py
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):
