## Workflow Decision Tree

**Creating a new project?**
→ Start with `assets/settings.gradle.kts.template` for settings and module includes  
→ Start with `assets/libs.versions.toml.template` for the version catalog  
→ Copy all files from `assets/convention/` to `build-logic/convention/src/main/kotlin/`  
→ Create `build-logic/settings.gradle.kts` (see `assets/convention/QUICK_REFERENCE.md`)  
→ Add `includeBuild("build-logic")` to root `settings.gradle.kts`  
→ Add plugin entries to `gradle/libs.versions.toml` (see `assets/convention/QUICK_REFERENCE.md`)
→ Copy `assets/proguard-rules.pro.template` to `app/proguard-rules.pro`
→ Read [modularization.md](references/modularization.md) for structure and module types  
→ Use [gradle-setup.md](references/gradle-setup.md) for build files and build logic  

**Configuring Gradle/build files?**
→ Use [gradle-setup.md](references/gradle-setup.md) for module `build.gradle.kts` patterns  
→ Use [gradle-setup.md](references/gradle-setup.md) → "Build Performance" for optimization workflow, diagnostics, and bottleneck troubleshooting  
→ Copy convention plugins from `assets/convention/` to `build-logic/` in your project  
→ See `assets/convention/QUICK_REFERENCE.md` for setup instructions and examples  
→ Copy `assets/proguard-rules.pro.template` to `app/proguard-rules.pro` for R8 rules  

**Setting up code quality / Detekt?**
→ Use [code-quality.md](references/code-quality.md) for Detekt convention plugin setup  
→ Start from `assets/detekt.yml.template` for rules and enable Compose rules  

**Adding or updating dependencies?**
→ Follow [dependencies.md](references/dependencies.md)  
→ Update `assets/libs.versions.toml.template` if the dependency is missing  

**Adding a new feature/module?**
→ Follow module naming in [modularization.md](references/modularization.md)  
→ Implement Presentation in the feature module  
→ Follow dependency flow: Feature → Core/Domain → Core/Data

**Building UI screens/components?**
→ Read [compose-patterns.md](references/compose-patterns.md) for screen architecture, state, components, modifiers  
→ Use [compose-patterns.md](references/compose-patterns.md) -> State Management -> "Loading and refresh UX" for stable layout during loads and refreshes (avoid full-screen spinners that wipe context)  
→ Use [android-theming.md](references/android-theming.md) for Material 3 colors, typography, and shapes  
→ **Always** align Kotlin code with [kotlin-patterns.md](references/kotlin-patterns.md)  
→ Create Screen + ViewModel + UiState in the feature module  
→ Use shared components from `core/ui` when possible

**Handling State and Events?**
→ Use `StateFlow` for state; `Channel` + `receiveAsFlow()` for strict one-shot UI commands; `SharedFlow` for multicast or replay-intended events (see [coroutines-patterns.md](references/coroutines-patterns.md))
→ Survive process death with `SavedStateHandle` (see [compose-patterns.md](references/compose-patterns.md))

**Setting up app theme (colors, typography, shapes)?**
→ Follow [android-theming.md](references/android-theming.md) for Material 3 theming and dynamic colors  
→ Use semantic color roles from `MaterialTheme.colorScheme` (never hardcoded colors); pair every fill with its `on*` partner - see [Color Pairing Rules](references/android-theming.md#color-pairing-rules)  
→ Declare the **full** M3 color set in `Color.kt` (surface containers, dim/bright, `*Fixed`/`*FixedDim`) so dynamic color and contrast variants stay consistent - see [Full Color Role Reference](references/android-theming.md#full-color-role-reference-m3) and [Surface Container Hierarchy](references/android-theming.md#surface-container-hierarchy)  
→ Express depth via container tone first, shadows only for components that float over arbitrary content - see [Tonal Elevation vs Shadows](references/android-theming.md#tonal-elevation-vs-shadows)  
→ Use `outline` for interactive borders/focus, `outlineVariant` for decorative dividers - see [`outline` vs `outlineVariant`](references/android-theming.md#outline-vs-outlinevariant)  
→ Support light/dark themes with user preference toggle  
→ Enable dynamic color (Material You) for API 31+, harmonize brand/extended colors against `primary` - see [Brand Color Harmonization](references/android-theming.md#brand-color-harmonization)  
→ Honor the system contrast slider on Android 14+ (API 34) by shipping Medium/High-contrast scheme variants and reading `UiModeManager.getContrast()` - see [User Contrast Preference](references/android-theming.md#user-contrast-preference-android-14)
