What's Included

Image Formats Reference

Deep coverage of JPEG, PNG, WebP, AVIF, GIF, SVG, HEIC, JPEG XL. Includes compression algorithms, encoding options, browser support matrix, HDR & wide color gamut, and when to use each format.

Optimization Techniques

Quality settings for each format, lossy vs lossless compression, chroma subsampling, metadata handling, batch processing, automation pipelines, and practical SSIM/VMAF quality thresholds.

Responsive Images

Complete guide to srcset, sizes, picture element, art direction, density descriptors, container queries for images, and common responsive image patterns.

Performance Best Practices

Core Web Vitals optimization (LCP, CLS), fetchpriority attribute, lazy loading, preloading, placeholder strategies (LQIP, blur-up, blurhash), CDN caching, and performance budgets.

Tools Reference

CDN URL patterns (Sirv, Cloudinary, imgix, ImageEngine, Bunny CDN), AI tools (Sirv AI Studio), edge/serverless processing, CLI tools (ImageMagick, Sharp, cwebp, avifenc), and build tool integrations.

Quick Install

Install with one command using add-skill:

npx add-skill IgorVaryvoda/image-optimization-skill

This installs all 4 skills to your AI coding environment.

MCP Server (Optional)

Enable direct image processing with the Sirv AI MCP server. Add to your MCP config (.mcp.json or equivalent):

{
  "mcpServers": {
    "sirv-ai": {
      "command": "npx",
      "args": ["-y", "sirv-ai-mcp-server"],
      "env": {
        "SIRV_AI_BASE_URL": "https://www.sirv.studio"
      }
    }
  }
}

Restart your AI assistant after adding. You'll authorize with your Sirv AI Studio account on first use.

Manual Installation
  1. 1. Download the .skill file above
  2. 2. Move it to your skills directory (e.g., ~/.claude/skills/ for Claude Code)
  3. 3. The skill activates automatically when you work on image-related tasks
Example Usage

Once installed, your AI assistant will automatically use the relevant skill when you ask about:

image-optimization

  • "What format should I use for this hero image?"
  • "Set up responsive images with WebP fallback"

sirv-api

  • "Upload images to Sirv via their REST API"
  • "Search for all JPEGs uploaded this week"

sirv-ai-studio

  • "Remove backgrounds from product images in batch"
  • "Generate lifestyle scenes for my products"

sirv-dynamic-imaging

  • "Add a watermark to images via URL params"
  • "Create a Sirv profile for thumbnails"
Supported AI Coding Assistants

These skills work with AI coding assistants that support the .skill format or custom instructions:

  • Claude Code - Anthropic's CLI tool
  • Cursor - AI code editor

Example Conversations
You
"What quality should I use for my e-commerce product images in WebP?"
AI
"For e-commerce product images, I recommend WebP quality 80-85. Product detail matters for purchase decisions, so aim for SSIM ≥ 0.97. You can go slightly lower (75-80) for thumbnails. Always test with your actual products - fabrics and textures may need higher quality than solid-color items."
You
"I need to remove backgrounds from 500 product photos for my catalog"
AI
"Sirv AI Studio is perfect for this. Use Batch Background Removal - upload your images, select BiRefNet v2 for fast processing (1-2 credits each), and download as a ZIP or auto-upload to Sirv CDN. Pro tier handles up to 500 images per batch. For best results, use the 'Heavy' preset for complex edges like hair or fabric."
You
"How do I add a watermark to images using Sirv URL parameters?"
AI
"Add ?watermark=/logo.png&watermark.position=southeast&watermark.scale.width=15%&watermark.opacity=40 to your image URL. You can also create a reusable profile at /Profiles/watermarked and use ?profile=watermarked on any image."
Frequently Asked Questions
Will this work with my framework (Next.js, Astro, etc.)?

Yes! The skill includes framework-specific guidance for Next.js, Astro, Nuxt, Vite, Webpack, and more. It covers both native image components and manual optimization approaches.

How do I update to the latest version?

Re-run the install command: npx add-skill IgorVaryvoda/image-optimization-skill. This will replace the existing skills with the latest versions.

Does this skill work with other AI assistants?

Yes! While originally designed for Claude Code, these skills work with Cursor, Codex CLI, Antigravity, and any AI coding assistant that supports custom instructions or .skill/.md files.

How does the skill activate?

Most AI coding assistants automatically load relevant skills based on context. When you ask about image optimization, formats, responsive images, or related topics, the skill's knowledge is used to provide better answers.
