Generate a complete set of favicons from the source image at $1 and update the project's HTML with the appropriate link tags.

When to Use

• You need to generate a complete favicon set from a single source image.
• The task includes placing the assets in the correct framework-specific static directory and updating HTML link tags.
• You want one workflow that validates the source image, detects the project type, and writes the right favicon outputs.

Prerequisites

First, verify ImageMagick v7+ is installed by running:

which magick

If not found, stop and instruct the user to install it:

• macOS: brew install imagemagick
• Linux: sudo apt install imagemagick

Step 1: Validate Source Image

1. Verify the source image exists at the provided path: $1
2. Check the file extension is a supported format (PNG, JPG, JPEG, SVG, WEBP, GIF)
3. If the file doesn't exist or isn't a valid image format, report the error and stop

Note whether the source is an SVG file - if so, it will also be copied as favicon.svg.

Step 2: Detect Project Type and Static Assets Directory

Detect the project type and determine where static assets should be placed. Check in this order:

Framework	Detection	Static Assets Directory
Rails	config/routes.rb exists	public/
Next.js	next.config.* exists	public/
Gatsby	gatsby-config.* exists	static/
SvelteKit	svelte.config.* exists	static/
Astro	astro.config.* exists	public/
