Husi Preference UI conventions for Compose Multiplatform. Use whenever editing any settings or profile-editor preference UI in composeApp/, including Preference.kt helpers, preferenceGroup cards, PreferenceCategory layout, conditional preference sections, ColoredIconContainer, PreferenceMaskColors, PreferenceShapes, platform SettingsScreenPlatform actuals, or icons for me.zhanghai.compose.preference rows.
Husi project's topbar design system. Use whenever adding a new screen in composeApp/, editing a Scaffold, building Compose UI with a topBar / tabs / search bar, or wiring scroll-driven color changes (scrollBehavior / pinnedScrollBehavior). If a topbar is involved at all, consult this skill — do not reach for Material 3's TopAppBar or AppBarWithSearch directly.
Husi actions overflow menu conventions for Compose Material3 DropdownMenuPopup. Use this whenever editing or creating a DropdownMenuPopup inside CapsuleTopBar or CapsuleSearchTopBar actions, adding a more_vert actions menu, touching MenuDefaults.Label section headers, DropdownMenuGroup shapes, checked/selected menu rows, or improving the visual hierarchy of topbar action menus in composeApp/.
Husi project's Kotlin/Compose Multiplatform testing conventions. Use whenever adding, updating, or debugging tests under composeApp/ — ViewModels, updaters, ktx helpers, anything in commonTest/desktopTest. Also use when a piece of production code needs a DI seam to become testable (HTTP, DataStore, Libcore). Do not reach for mockk first or invent a new base class — consult this skill before writing the first test in a new file.
