Web and frontend performance optimization. Use when user asks to "optimize performance", "improve loading time", "lazy loading", "code splitting", "bundle size", "Core Web Vitals", "image optimization", "CSS/JS minification", "caching strategies", "performance profiling", or mentions web performance and user experience metrics.
refinery
by vxcozy
Convergence loop that iteratively improves work until quality thresholds are met. Scores, diagnoses specific weaknesses, rewrites, re-scores, and repeats until all dimensions reach 8/10 or diminishing returns are detected. Use when you want to refine or iterate on work, after the analyst gives a REVISE verdict, or when output quality is below your bar. Part of the architect-system loop. Outputs to system/refinery-log.md.
