react-native-architecture
Structure React Native projects with feature-first organization and separation of concerns. Use when structuring a React Native project or applying clean architecture patterns.
What this skill does
# React Native Architecture ## **Priority: P0 (CRITICAL)** ## Organize by Feature - **Feature-First**: Organize by feature/module, not by type. - **Colocation**: Keep related files together (screens, components, hooks within feature). - **Separation**: UI (screens/components) separate from logic (hooks/services). See [folder structure reference](references/folder-structure.md) for full directory tree and path alias configuration. - **Atomic Components**: Reusable components in `/components`. Feature-specific in feature folder. - **Absolute Imports**: Configure tsconfig.json paths for clean imports. - **Single Responsibility**: Each file one clear purpose. - **Expo vs CLI**: Structure works for both. Expo uses `app.json`, CLI uses `index.js`. ## Anti-Patterns - **No Type-Based Folders**: Avoid `/containers`, `/screens` at root. Use features. - **No Logic in Screens**: Extract to hooks or services. - **No Circular Deps**: Features should not import from each other directly. - **No Deep Nesting**: Max 3 levels deep. ## Navigation Strategy - **Expo Router**: Use for new projects, web-parity, and file-based routing. - **React Navigation**: Use for complex deep-linking, legacy apps, or high-customization needs. ## Verification Checklist (Mandatory) - [ ] **Feature-First**: file inside feature directory? - [ ] **Colocation**: hooks/services colocated with screens? - [ ] **Logic-Free Screens**: there any business logic in screen component? - [ ] **Navigation Choice**: project use navigation strategy defined above? ## References See [references/folder-structure.md](references/folder-structure.md) for full directory tree, path alias config, and service layer patterns.

generating-lwc-components
IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
document-processor-api
IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.

tanstack-query
IncludedManage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.
accelint-nextjs-best-practices
IncludedNext.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
