favicon

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: ```bash 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** | `svel...
