React Native renderer that converts JSON specs into native mobile component trees with standard components, data binding, visibility, actions, and dynamic props.

Before starting development, assess the current project state:

Expert guidance for building type-safe Expo React Native applications with modern best practices. \n \n Covers TypeScript standards, functional component patterns, and strict mode configuration with interfaces over types \n Includes responsive design strategies using Flexbox, dark mode support, and accessibility standards via ARIA roles \n Addresses performance optimization through image lazy loading, code splitting with Suspense, and state management with Context/Zustand \n Provides error handl

Prescriptive workflow for incremental adoption of React Native in existing native apps using @callstack/react-native-brownfield, from initial setup through phased host integration.

Design constraints and patterns for building stateless, observable cloud-native applications in Rust. \n \n Enforces stateless design, graceful shutdown with SIGTERM handling, and 12-factor configuration via environment variables to support Kubernetes orchestration and zero-downtime deployments \n Requires distributed tracing with tracing and OpenTelemetry, plus dedicated /health and /ready endpoints for liveness and readiness probes \n Recommends key crates: tonic for gRPC services, kube and ku

Cross-platform native interoperability for Flutter apps on Android, iOS, and Web. \n \n Provides decision logic to select the optimal integration strategy: FFI for C/C++ code, Platform Channels for OS-specific APIs, Platform Views for native UI components, and JS Interop for web \n Implements modern FFI architecture using build hooks (Flutter 3.38+) with native toolchain compilation and Dart bindings \n Supports asynchronous Platform Channels (MethodChannel) with complete Kotlin and Swift implem

Complete guide for provisioning, configuring, and securing Firestore Enterprise Native Mode. \n \n Covers provisioning setup, data model organization, and SDK integration across multiple languages \n Includes comprehensive security rules guidance for protecting data access and enforcing authorization policies \n Provides index configuration and query performance optimization best practices \n Structured reference documentation for each major setup and operational area \n

Network requests, API calls, and data fetching for Expo apps with caching, error handling, and offline support. \n \n Covers fetch API, React Query, error handling patterns, token management with expo-secure-store, and retry logic with exponential backoff \n Includes offline-first strategies using NetInfo and React Query persistence, plus environment variable configuration with EXPO_PUBLIC_ prefix for client-side URLs \n Supports Expo Router data loaders ( useLoaderData ) for route-level data lo
