Core Web Vitals are essential for fast, reliable user experiences, but teams often struggle to consistently verify targets, budgets, and remediation efforts across projects.
Run the web-vitals-checklist on your project to identify gaps against LCP, INP, CLS, FCP, and TTFB targets.

To check Core Web Vitals performance issues, you measure LCP, INP, CLS, FCP, and TTFB across pages to diagnose gaps and guide optimizations. This provides a structured checklist verifying targets for each metric.
Setting performance budgets for LCP and CLS involves defining concrete metric targets and applying structured checklists during code reviews. This ensures consistent performance quality and catches regressions before deployment.
Core Web Vitals auditing applies to web projects across frameworks, diagnosing performance gaps regardless of the specific stack. It measures standard metrics like TTFB and INP to verify targets consistently.
LCP performance target verification fails when teams lack structured checklists to consistently measure and diagnose gaps across pages. Applying concrete targets during planning guides budget setting and prevents regressions.
Automating Core Web Vitals checks is supported through the web-vitals-auditor sub-agent, which identifies and verifies performance issues. It integrates with downstream remediation workflows for efficient performance engineering.
To diagnose web performance gaps, measure LCP, INP, CLS, FCP, and TTFB. These Core Web Vitals provide concrete targets and a structured checklist to identify issues across pages.
