Standard Vue 3 workflow with Composition API, <script setup> , and TypeScript as the default approach. \n \n Requires confirming project architecture upfront and reading core references on reactivity, SFCs, component data flow, and composables before implementation \n Enforces minimal source state with ref / reactive , deriving everything possible with computed , and keeping templates declarative \n Mandates component splitting when responsibilities exceed one clear purpose, with entry/root

Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 45 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.

WordPress performance optimization guidelines across database, caching, assets, and plugin architecture. \n \n 34 rules organized by impact across 8 categories: database optimization, caching strategies, asset management, theme performance, plugin architecture, media optimization, API/AJAX, and advanced patterns \n Covers critical areas including WP_Query optimization, transient and object cache usage, proper asset enqueueing, and REST API caching \n Designed for code review and generation workf

Vue 3 Options API patterns, TypeScript integration strategies, and context-binding gotchas. \n \n Covers TypeScript type safety for component properties, this context, prop validators, event handlers, complex types, provide/inject, and computed return types \n Addresses common method and lifecycle hook pitfalls: arrow function binding issues, context loss, and stateful method state leakage across instances \n Organized as a reference guide with linked examples for each pattern and anti-pattern \

Server Components by default, client interactivity on demand, with structured data fetching and caching strategies. \n \n Server Components handle data fetching and static content; Client Components ('use client') manage forms, state, and event handlers. Split responsibilities when both are needed. \n Data fetching uses static caching by default, with ISR (time-based revalidation) and dynamic (no-store) options for different freshness requirements. \n Routing relies on file conventions (page.tsx
