What problem does it solve?

This Skill prevents broken Wear OS Compose Material3 implementations by enforcing correct library/Kotlin compatibility, version pinning, and sample-based parameter usage.

Core Features & Use Cases

• Safe version selection and constraints: Determines the latest stable androidx.wear.compose:compose-material3 version (highest non-prerelease) and enforces Kotlin/Compose compiler requirements and minSdk >= 25.
• Deterministic migration workflow: Applies Material3 migration guidance, avoids unsupported libraries (like Horologist), and validates component changes against canonical mappings.
• Sample-first component correctness: Requires extraction and local reading of the official <artifact>-<version>-samples-sources.jar contents before any implementation, ensuring slot names, defaults, and behaviors match the exact library version.
• Component checklist to avoid subtle UI/behavior regressions: Provides Wear-specific guidance (e.g., TransformingLazyColumn rules, AppScaffold/ScreenScaffold structure, overscroll handling for EdgeButton, typography/color usage).

Quick Start

Use this skill to migrate your Wear Compose project to Material3 by extracting and reading the version-matched component samples, then implementing the required components following the checklist guidance.
