Use when users request "ESLint setup", "Prettier config", "linting configuration", "code formatting", or "lint rules".explaining-codepatricio0312revExplains code with visual diagrams and analogies. Use when explaining how code works, teaching about a codebase, or when the user asks "how does this work?jsdoc-typescript-docspatricio0312revDocuments TypeScript code with JSDoc comments, generates API documentation, and creates type-safe documentation. Use when users request "JSDoc", "code documentation", "API docs", "TypeDoc", or "inline documentation".multi-tenant-safety-checkerpatricio0312revEnsures tenant isolation at query and policy level using Row Level Security, automated testing, and security audits. Prevents data leakage between tenants. Use for "multi-tenancy", "tenant isolation", "RLS", or "data security".nginx-config-optimizerpatricio0312revOptimizes Nginx configurations for performance, security, caching, and load balancing with modern best practices. Use when users request "Nginx setup", "reverse proxy", "load balancer", "web server config", or "Nginx optimization".postman-collection-generatorpatricio0312revGenerates Postman collection JSON files from Express, Next.js, Fastify, Hono, or other API routes. Scans route definitions, extracts endpoints, methods, params, and creates importable collections. Use when users request "generate postman collection", "export to postman", "create postman file", or "postman import".websocket-realtime-builderpatricio0312revImplements real-time features using WebSockets with Socket.io, rooms, authentication, and reconnection handling. Use when users request "real-time updates", "WebSocket", "Socket.io", "live chat", or "push notifications".client-side-renderingpatternsdevTeaches client-side rendering (CSR) for React applications. Use when building highly interactive apps where SEO is not a priority and the UI is driven by user actions.command-patternpatternsdevTeaches the command pattern for decoupling task execution from invocation. Use when you need undo/redo functionality, queued operations, or want to decouple the object that invokes an operation from the one that performs it.compound-patternpatternsdevTeaches the compound component pattern for shared implicit state. Use when building related components like tabs, accordions, or dropdowns that need to coordinate without explicit prop passing.factory-patternpatternsdevTeaches the factory pattern for flexible object creation. Use when you need to create objects dynamically without using the new keyword or when object creation logic should be centralized.flyweight-patternpatternsdevTeaches the flyweight pattern for memory optimization. Use when your application creates large numbers of similar objects and memory consumption is a concern.hoc-patternpatternsdevTeaches the Higher-Order Component (HOC) pattern for logic reuse. Use when you need to share cross-cutting concerns like authentication, logging, or data fetching across multiple components.hooks-patternpatternsdevTeaches React Hooks for reusing stateful logic across components. Use when extracting shared behavior like form handling, subscriptions, or side effects into reusable custom hooks.import-on-interactionpatternsdevTeaches interaction-based lazy loading for non-critical resources. Use when you have heavy components or libraries that are only needed after user interaction like clicks, hovers, or form input.import-on-visibilitypatternsdevTeaches visibility-based lazy loading using Intersection Observer. Use when you have below-the-fold components or images that don't need to load until the user scrolls to them.incremental-static-renderingpatternsdevTeaches Incremental Static Regeneration (ISR) for updating static content post-build. Use when you have static pages that need periodic updates without a full site rebuild.islands-architecturepatternsdevTeaches the islands architecture pattern for partial hydration. Use when building content-heavy sites where most of the page is static and only small regions need interactivity.js-performance-patternspatternsdevProvides framework-agnostic JavaScript runtime performance patterns. Use when optimizing hot paths, loops, DOM operations, caching, or data structure choices in performance-critical code.loading-sequencepatternsdevTeaches resource loading sequence optimization for Core Web Vitals. Use when you need to improve FCP, LCP, or FID by reordering how critical resources are discovered and loaded.mediator-patternpatternsdevTeaches the mediator pattern for centralized component communication. Use when multiple components need to communicate and direct coupling between them creates complexity or tight dependencies.mixin-patternpatternsdevTeaches the mixin pattern for sharing functionality without inheritance. Use when you need to add reusable behavior to multiple objects or classes that don't share a common ancestor.module-patternpatternsdevTeaches the module pattern for code organization and encapsulation. Use when structuring JavaScript into reusable, maintainable pieces with clear public and private boundaries.observer-patternpatternsdevTeaches the observer pattern for event-driven communication. Use when you need decoupled publish/subscribe behavior where multiple parts of your system react to state changes or events.prefetchpatternsdevTeaches resource prefetching strategies for faster navigation. Use when you can predict which resources the user will need next and want to load them during idle time.preloadpatternsdevTeaches resource preloading to prioritize critical assets. Use when critical resources like fonts, hero images, or key scripts are discovered late in the loading waterfall.presentational-container-patternpatternsdevTeaches the presentational/container pattern for separating view and logic. Use when you want to isolate data fetching and business logic from UI rendering for better testability and reuse.progressive-hydrationpatternsdevTeaches progressive hydration for prioritized client-side interactivity. Use when server-rendered pages have non-critical sections whose JavaScript can be deferred to improve Time to Interactive.prototype-patternpatternsdevTeaches the prototype pattern for property sharing via the prototype chain. Use when creating many objects of the same type that should share methods or properties efficiently.provider-patternpatternsdevTeaches the provider pattern for sharing data across component trees. Use when multiple nested components need access to the same data and prop drilling becomes unwieldy.proxy-patternpatternsdevTeaches the proxy pattern for intercepting object operations. Use when you need validation, logging, formatting, or access control on property access, assignment, or function invocation.prplpatternsdevTeaches the PRPL pattern for optimizing initial page load. Use when building Progressive Web Apps or when you need to push critical resources, render the initial route, pre-cache remaining routes, and lazy-load on demand.
