Performance

Editor's Note

This is a surgical performance fix skill for Flows apps that measures first, then systematically hunts down and patches the usual culprits: unnecessary re-renders from inline objects and arrow functions, expensive instances.list calls that should be instances.query, client-side filtering that belongs in the API request, and missing pagination limits. It's opinionated about moving compute server-side and swapping Postgres-hitting DMS APIs for Elasticsearch-backed ones in read-heavy paths. Every fix includes before/after measurement via Lighthouse and React Profiler. Use it when your app feels sluggish or when you see long lists rendering without virtualization. It won't just tell you what's slow, it rewrites the code.
