Checks that production JavaScript is minified and tree-shaken to reduce bundle size and improve page load performance.
Ensures JavaScript shipped to production is minified and optimized (comments removed, whitespace collapsed, and dead code eliminated) so pages load faster, parse quicker, and use less bandwidth — especially on mobile. Practical guidance for configuring common build tools and verifying results in the browser is included.
Run this when auditing frontend performance, preparing a production build, or reviewing CI/CD build outputs. Trigger on large bundle sizes, slow first contentful paint (FCP), or when migrating frameworks/build tools.
Works well with agents that inspect web projects and build configs (Copilot/Code assistants, static analysis agents, and CI-integrated bots).
