performance-optimization

performance-optimization is a Web performance & accessibility skill for AI agents, published by sanky369 in the vibe-building-skills repository on GitHub. Skillspace rates performance-optimization C (74/100) and it passed the safety scan; the rating is based on static analysis only.

Diagnose and fix how slow a frontend feels and measures: optimistic UI for mutations, latency masking (skeletons, blur-up, preloading, staggering), request batching/deduplication, and Core Web Vitals (LCP/INP/CLS) remediation. Use when the user says 'the app feels slow', 'clicks feel laggy', 'improve performance', 'my Lighthouse score is bad', 'fix my Core Web Vitals / LCP / CLS', 'make saves feel instant', or when interactions visibly wait on the network. Produces a performance audit (findings ranked by user impact, with measured or user-reported evidence) plus the implemented fixes — optimistic mutation code, masking treatments, and network-layer improvements.

Unproven: rated by static analysis only, not yet compared head-to-head.

Not launch-quality. It is graded C with a clean safety verdict, but our quality filters exclude it: it is a near-duplicate variant of another skill. So it is not in our launch-quality set, the skills our MCP server searches and recommends. How launch-quality is decided
