SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit performance budgets against Core Web Vitals and related metrics for a given page or feature, helping teams prevent slow experiences.

Core Features & Use Cases

  • Defines performance budgets for LCP, INP, CLS, bundle size, and API latency.
  • Identifies budget violations and suggests actionable optimizations such as image optimization, code splitting, lazy loading, and caching strategies.
  • Use Case: Running a performance audit before a feature release to ensure page performance meets thresholds across critical paths.

Quick Start

Run the audit-performance skill on a target page or endpoint to generate a performance budget audit and actionable recommendations.

FAQPage Schema
How do I audit performance budgets against Core Web Vitals?

To audit performance budgets against Core Web Vitals, define thresholds for LCP, INP, CLS, bundle size, and API latency for a target page. The audit detects budget violations and produces prioritized recommendations to prevent slow experiences.

What's the best way to enforce bundle size and API latency limits during development?

Enforcing bundle size and API latency limits during development involves defining performance budgets for targeted features or endpoints. The audit identifies threshold violations and suggests actionable optimizations like code splitting and caching improvements.

Can I check Core Web Vitals thresholds for a specific page before a feature release?

Yes, you can check Core Web Vitals thresholds for a specific page before a feature release by running a performance budget audit. It evaluates critical paths across web applications to ensure page performance meets LCP, INP, and CLS requirements.

Why does my web performance audit recommend code splitting and lazy loading?

A web performance audit recommends code splitting and lazy loading when it detects performance budget violations related to bundle size. These prioritized optimizations reduce initial load times and help meet Core Web Vitals thresholds.

Does the performance budget audit work across different deployment environments?

Yes, the performance budget audit works across different deployment environments. You can apply it during development and optimization to pages, features, and endpoints across web applications and projects to ensure consistent performance.
