What problem does it solve?

This Skill helps teams who face slow builds, oversized bundles, or CI timeouts by providing a structured approach to measure, analyze, and reduce build time and bundle size for web applications.

Core Features & Use Cases

• Measure build performance and identify bottlenecks, largest dependencies, and slow build steps.
• Optimize dependency usage and replace or lazily load heavy libraries to reduce initial bundle weight.
• Implement code splitting, tree shaking, and manual chunking strategies for route and vendor separation.
• Tune build configuration and enable caching strategies in CI to speed up developer feedback loops and deployments.
• Use faster toolchains and package managers, optimize assets and images, and set bundle size budgets to enforce limits.

Quick Start

Run an analysis of the repository build to identify top time sinks, largest modules, and a prioritized list of changes to reduce build time and bundle size.
