## Prerequisites and compatibility

1. **Current Wear OS Compose version in-use:** To find the installed library version, read `gradle/libs.versions.toml` or `build.gradle.kts` directly. Don't run `./gradlew dependencies` or other shell commands to resolve versions.
2. **Wear OS Compose Material3 version:** If an internal tool is available to establish the **latest stable version** `{VERSION}` of `androidx.wear.compose:compose-material3`, use that tool.
   - Otherwise, fetch the [official Maven metadata XML](https://dl.google.com/dl/android/maven2/androidx/wear/compose/compose-material3/maven-metadata.xml) to identify `{VERSION}` (highest number, ignoring `-alpha`, `-beta`, or `-rc`).
3. **Strict compliance:** If a version is listed as stable, you MUST use it, unless overridden by the user. Do not downgrade based on initial "Unresolved reference" errors in the editor or outdated web search results.
4. **Kotlin \& Compose compiler:** Use Kotlin **2.0.0+** with the `org.jetbrains.kotlin.plugin.compose` Gradle plugin.
5. **Min SDK:** Ensure `minSdk` is at least **25**.
6. **Compile SDK \& AGP:** Ensure `compileSdk` and AGP meet the library's AAR metadata floors (`compileSdk >= 35` and `AGP >= 8.6.0` for `1.6.x`; `compileSdk >= 37` and `AGP >= 9.1.0` for `1.7.x`).

## Gotchas

1. **Mandatory sync and validation:** After updating versions in `libs.versions.toml` or `build.gradle.kts`, perform a Gradle sync (or `./gradlew assembleDebug`) before refactoring, and run `./gradlew assembleDebug` after refactoring to verify the build.
2. **Prohibition of guessing (error protocol):** If you encounter an 'Unresolved Reference' or API mismatch after a successful sync, do not attempt to 'fix' it by downgrading the library version.

## Capabilities and tools

### Capability 1: Migration, updates, and adding features

Use this guidance when migrating from an older version of Wear OS Compose or
Horologist, updating an existing Wear Compose Material3 project, or adding
features.

1. Unless otherwise indicated by the developer, use the latest stable version of Wear Compose Material3 from `{VERSION}` (superseding any literal version strings in the migration guide).
2. When migrating from Material 2.5 or Horologist, read the [migration guide](references/android/training/wearables/compose/migrate-to-material3.md) and use its official component mappings.
3. Before refactoring any component (for example, `Chip` -\> `Button`), check the parameter names, slot types, and "Expressive" design tokens.
4. Do not use the Horologist Composables, Compose Layout, or Compose Material libraries; replace Horologist components with Wear Compose M3 equivalents (`AppScaffold` -\> M3 `AppScaffold`, `ScreenScaffold` -\> M3 `ScreenScaffold`, `ScalingLazyColumn` -\> `TransformingLazyColumn`, `ResponsiveListHeader` -\> `ListHeader`, `PagerScreen` -\> `HorizontalPagerScaffold`, `Chip` -\> `Button`, `Confirmation` -\> `ConfirmationDialog`).
5. **Always** check against the component guidance in Capability 3.
6. Expect screenshot tests to fail when migrating or updating components: expected defaults for padding and positioning will have changed. Do not seek to artificially match the previous screenshot, but give preference to the Material3 defaults.

### Capability 2: Component samples

Use this table of reference to find canonical samples for Wear Compose
components.
When working with a Wear Compose component, you must use the samples linked
from the table to ensure you know how to correctly use it.

**Important:** Symbols marked with `[alpha]`, `[beta]`, or `[rc]` are only
available in that pre-release track and are **not** in stable `{VERSION}`. Do
not use them unless the project explicitly targets that pre-release version.
