Implement signal-based reactive state management in Angular v20+. Use for creating reactive state with signal(), derived state with computed(), dependent state with linkedSignal(), and side effects with effect(). Triggers on state management questions, converting from BehaviorSubject/Observable patterns to signals, or implementing reactive data flows.
Use when SwiftUI view debugging requires systematic investigation - view updates not working after basic troubleshooting, intermittent UI issues, complex state dependencies, or when Self._printChanges() shows unexpected update patterns - systematic diagnostic workflows with Instruments integration
Expert-level Dart, Flutter, mobile development, and cross-platform apps
Zustand state management patterns for React applications. Use when implementing client-side global state, persisted state, or computed values. Lightweight alternative to Redux with minimal boilerplate.
Build cross-platform mobile applications using React Native. Use when the user wants to create, develop, or work with React Native apps for iOS and Android. Triggers include requests to build mobile apps, create React Native components, set up navigation, integrate native modules, handle app state management, implement animations, or work with React Native specific features like FlatList, StyleSheet, or platform-specific code.
Build a conversational AI assistant with memory and state. Use when you need a customer support chatbot, helpdesk bot, onboarding assistant, sales qualification bot, FAQ assistant, or any multi-turn conversational AI. Powered by DSPy for response quality and LangGraph for conversation state management.
Managing cloud infrastructure using declarative and imperative IaC tools. Use when provisioning cloud resources (Terraform/OpenTofu for multi-cloud, Pulumi for developer-centric workflows, AWS CDK for AWS-native infrastructure), designing reusable modules, implementing state management patterns, or establishing infrastructure deployment workflows.
Server-driven architecture patterns for Inertia Rails + React. Load this FIRST when building any Inertia page or feature — it routes to the right skill. Decision matrix for data loading, forms, navigation, state management. NEVER useEffect+fetch, NEVER redirect_to for external URLs (use inertia_location), NEVER react-hook-form (use Form component). MUST invoke when adding pages, models with views, CRUD, or displaying data in an Inertia Rails app. ALWAYS `render inertia: { key: value }` to pass data — `@ivars` are NOT auto-passed as props.
Comprehensive best practices for Terraform infrastructure as code from Anton Babenko's community guide
Apply React best practices when writing or reviewing React code. Use when building components, reviewing PRs, refactoring React code, fixing performance issues, debugging re-renders, structuring state and data flow, converting useEffect to loaders, building forms, or asking "how should I structure this component".
Guides when NOT to use useEffect and suggests better alternatives. Use when reviewing React code, troubleshooting performance, or considering useEffect for derived state or form resets.
Cross-platform development with Flutter and Dart for iOS, Android, Web, Desktop, and embedded. Use when building Flutter apps, implementing Material/Cupertino design, or optimizing Dart code.
