Does this skill support custom serialization logic?

Yes, it includes patterns for custom serializers, such as handling Instant types or epoch milliseconds, to accommodate specific API requirements or platform-specific data formats.

What is the primary benefit of using shared models in KMP?

Shared models ensure a single source of truth for your data structures across Android, iOS, and other platforms, significantly reducing bugs caused by mismatched data contracts.

How does the skill handle data validation?

It implements a dual approach: 'init' blocks for immediate field-level validation and dedicated ValidationResult classes for complex, multi-field business logic validation.

Can I use these models for frontend UI state management?

Absolutely. The skill provides specific templates for sealed hierarchies (Loading, Success, Error) which are ideal for managing UI states in a type-safe manner across platforms.

Implements cross-platform domain models and serialization patterns for Kotlin Multiplatform projects using kotlinx.serialization.

This skill provides a standardized framework for designing and implementing immutable data models within the shared module of Kotlin Multiplatform (KMP) applications. It streamlines the creation of domain-specific models, sealed hierarchies for state management, and paginated response structures, ensuring data consistency across Android, iOS, Web, and Desktop. By enforcing best practices such as inline validation and platform-independent types, it helps developers maintain a clean, type-safe contract between different platforms while leveraging the full power of kotlinx.serialization.
