About this skill

What it does

This skill optimizes Next.js 15 applications by analyzing build configurations and runtime behavior to identify bottlenecks. It automatically applies best practices such as code splitting, image optimization, and efficient caching strategies to reduce load times and improve Core Web Vitals.

When to use it

  • Pre-launch audits: Run before deployment to ensure the application meets performance benchmarks for search engines and user experience.
  • Bundle size reduction: Implement when JavaScript bundles are too large, causing slow initial page loads on mobile devices.
  • Image-heavy sites: Optimize rendering for e-commerce or portfolio sites containing numerous high-resolution assets.
  • SEO improvements: Enhance indexing speed by fixing render-blocking resources and improving First Contentful Paint (FCP).

Key capabilities

  • Analyzes Next.js 15 specific build pipelines for inefficiencies.
  • Generates actionable reports on Lighthouse scores and performance metrics.
  • Suggests configuration changes for next.config.js to enable advanced features like React Server Components optimization.
  • Identifies opportunities for dynamic imports and lazy loading of non-critical components.

Example prompts

  • "Analyze my Next.js 15 project structure and suggest specific changes to improve the Largest Contentful Paint score."
  • "Generate a performance report highlighting which images in my app are blocking the main thread and how to optimize them."
  • "Refactor my next.config.js file to enable automatic code splitting for better initial load times on slow networks."

Tips & gotchas

Ensure your project is already set up with Next.js 15, as this skill relies on version-specific features like Turbopack. Always test performance changes in a staging environment before applying them to production to avoid unintended side effects.
