Practical performance and bundle-size guidelines for React and Next.js apps — prioritized rules and patterns to avoid common performance pitfalls.
Provides a concise, prioritized rulebook for React and Next.js performance: eliminating waterfalls, reducing bundle size, server-side and client-side performance patterns, and rendering/re-render strategies. The skill summarizes rules and points to individual rule files with examples.
Apply during code reviews, refactors, or when authoring React/Next.js components and pages where performance, bundle size, or server rendering behaviour matters. Triggers when optimizing data fetching, bundling, hydration, or re-render hotspots.
rules/ files in the repo with detailed examples (has_references=false per fetch metadata but sibling rules exists)async-parallel, bundle-dynamic-imports, rerender-memo) with guidance for application.Useful with developer-focused assistants and code-writing agents (Copilot-style, Claude/GPT code assistants) that can read rule files and apply transformations or generate code suggestions.
