What problem does it solve? Building mobile features across Flutter, React Native, and native Swift iOS requires consistent architecture, state management, offline handling, and testing discipline that is hard to enforce manually across platforms. ## Core Features & Use Cases - Multi-platform implementation: Builds screens, widgets, providers, and API clients following Clean Architecture (Flutter), App/Core/Features/Shared layout (Swift), or TanStack Query patterns (React Native). - Offline-first and caching: Mandates repository-layer response caches with stale-while-revalidate reads and write invalidation using Drift, hyperoslo/Cache, or TanStack Query with MMKV persistence. - Verification workflow: Runs unit, widget, XCTest/XCUITest, and Maestro E2E checks with a self-verification checklist and an error recovery playbook. - Use Case: Ask it to create a native iOS todo list screen with pull-to-refresh; it generates a SwiftUI view, an @Observable view model, a service wrapping the swift-openapi-generator client, and XCTest coverage. ## Quick Start Ask the agent to build a mobile feature such as a login screen with JWT auth for your Flutter or Swift iOS app and let it implement and verify the code.
