Generate web assets including favicons, app icons (PWA), and social media meta images (Open Graph) for Facebook, Twitter, WhatsApp, and LinkedIn. Use when users need icons, favicons, social sharing images, or Open Graph images from logos or text slogans. Handles image resizing, text-to-image generation, and provides proper HTML meta tags.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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

How to install

The exact contents, by fingerprint

mdr add majiayu000/spellbook/web-asset-generator@sha256:7d4cd4f0aa61b78e

The line at the top of this page pins the label git:20260523.d39dd11, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
