Guide Legado Android UI migration from XML/View/RecyclerView/DialogFragment screens to Jetpack Compose and Material 3, and guide new Compose-first screens using standard Android architecture. Use when creating, migrating, rewriting, reviewing, or planning a Legado screen, Activity, Fragment, dialog, adapter, navigation destination, or settings page, especially when MainActivity navigation, MVI/UDF, StateFlow/SharedFlow, Koin ViewModels, domain/usecase boundaries, edge-to-edge insets, predictive back, or existing Compose component conventions matter.

Review existing Legado Jetpack Compose code for architecture, behavior, maintainability, and project convention issues. Use when auditing, reviewing, inspecting, evaluating, or finding problems in Legado Compose screens, routes, ViewModels, contracts, dialogs, sheets, navigation, or early Compose implementations, especially for MVI/UDF, StateFlow/SharedFlow, Clean Architecture, MainActivity navigation, legacy Activity compatibility, edge-to-edge insets, @Stable stability annotations, predictive back, and View-era mixed-pattern drift.
