Monitors and analyzes Vite and Rollup bundle sizes to enforce performance budgets and prevent production bloat.
The Bundle Size Analyzer skill empowers Claude to proactively manage web application performance by auditing Vite and Rollup build outputs. It provides automated size reporting, enforces strict performance budgets, and detects regressions by comparing pull requests against baseline metrics. By leveraging Vite manifests and asset graphs, the skill identifies the largest chunks and initial load impacts, helping developers maintain lean production builds and optimize asset delivery throughout the development lifecycle.
