Clean Architecture patterns for Android and KMP projects. Covers module boundaries, dependency inversion, UseCase/Repository patterns, and data layer design with Room, SQLDelight, and Ktor.

MVVM architecture for Flutter apps with unidirectional data flow and strict layer separation. \n \n Implements three-layer architecture: Data Layer (Services and Repositories), Domain Layer (UseCases for complex logic), and UI Layer (ViewModels and Views) \n Uses provider for dependency injection and ListenableBuilder for reactive UI updates with the Command pattern for user interactions \n Enforces unidirectional data flow: data flows down from Repositories to ViewModels to Views; events flow u

Architectural guidance for scalable Flutter apps using MVVM, layered design, and feature-first organization. \n \n Supports two project structures: feature-first (recommended for teams and medium-to-large apps) and layer-first (for smaller apps or solo developers) \n Defines three core layers: UI (Views and ViewModels), Data (Repositories and Services), and optional Domain (Use-cases) \n Covers key design patterns including Command Pattern, Result Type for error handling, Repository Pattern, and

This skill provides guidance for quality focused software development and architecture. It is based on Clean Architecture and Domain Driven Design principles.

Analyze, audit, and improve project structure.

Plan and optimize your website's page hierarchy, navigation, URL structure, and internal linking. \n \n Provides page hierarchy templates for six site types (SaaS, content, e-commerce, documentation, hybrid, small business) with typical depth and URL patterns \n Includes navigation design rules (header nav limits, dropdown organization, breadcrumb implementation) and URL structure principles (human-readable slugs, hierarchy alignment, redirect strategies) \n Delivers structured output: ASCII tre

Document significant technical decisions with structured context, rationale, and consequences. \n \n Provides five template formats (standard MADR, lightweight, Y-statement, deprecation, RFC-style) covering different decision complexity levels and team preferences \n Includes lifecycle management patterns for proposed, accepted, deprecated, and superseded decisions with clear status tracking \n Offers directory structure, indexing strategies, and automation tools (adr-tools) for maintaining ADR

Analyze codebases for architectural friction and propose module-deepening refactors as testability improvements. \n \n Explores codebases organically to surface shallow modules, tightly-coupled components, and untested seams rather than following rigid heuristics \n Applies John Ousterhout's \"deep module\" principle: small interfaces hiding large implementations for better testability and AI navigability \n Generates multiple radically different interface designs (minimalist, flexible, caller-o

Production-ready React Native patterns with Expo, navigation, offline-first architecture, and native module integration. \n \n Covers Expo Router for file-based navigation, authentication flows with secure token storage, and route protection patterns \n Includes offline-first data sync using React Query with AsyncStorage persistence and online status detection \n Demonstrates native module integration for haptics, biometrics, push notifications, and platform-specific code patterns \n Provides pe
