Full Analysis
- [SAFE]: The skill provides exhaustive and accurate instructions for frontend performance optimization, covering Core Web Vitals, bundle analysis, and rendering efficiency.
- [SAFE]: Reference code provided for Real User Monitoring (RUM) in 'references/phase4-monitoring.md' follows standard practices, using 'navigator.sendBeacon' or 'fetch' to transmit non-sensitive performance metrics to a relative API endpoint ('/api/vitals').
- [SAFE]: All third-party tools and libraries mentioned (e.g., Lighthouse, web-vitals, TanStack Virtual) are well-known, legitimate packages within the frontend ecosystem.
- [SAFE]: CI configuration examples for Lighthouse CI and size-limit use standard, documented patterns for performance regression prevention.
