Web Performance Evidence

Purpose

Make frontend performance work measurable and user-path focused rather than driven by generic score chasing or a required auditing vendor.

When to Use

Use this skill when:

• loading, rendering, interaction, image, font, CSS, or JavaScript cost affects a user journey;
• a change risks exceeding a bundle, request, or user-experience budget;
• a report identifies poor Core Web Vitals or inconsistent browser performance.

For Angular-specific budgets and framework optimizations, route to the existing Angular bundle-budget, Core Web Vitals, and performance skills.
