Feature Development Agents

Feature Development Agents

Specialized agents for building feature layers in parallel.

Overview

Feature Development Agents execute the three core layers of Clean Architecture:

1. data-layer-agent - Models, API routes, DataSource, Repository
2. ui-layer-agent - UiModel, ViewModel, Screens, Navigation
3. integration-agent - DI wiring, Gradle setup, Navigation registration, Spec generation

These agents run in parallel during feature creation (Phase 3) and are orchestrated by the creating-kmp-feature skill.

Architecture Pattern

├── presentation/

Agents

Data-Layer-Agent

Generates the data persistence layer with type-safe API contracts and error handling.

Generates:

• Domain models with @Serializable
• Ktor Resources (type-safe API routes)
• RemoteDataSource (interface + implementation)
• Repository (interface + implementation)
• All using Either<T> error handling

UI-Layer-Agent

Generates the presentation layer with the 4-state UI pattern.

Generates:

• UiModel (presentation models)
• ViewModel with 4-state pattern (Uninitialized/Loading/Success/Failed)
• Composable Screens with X-components
• Navigation with type-safe routes
• Uses setState { } for state updates

Integration-Agent

Completes integration of the feature into the application.

Completes 4 Integration Points:

1. settings.gradle.kts - Include module
2. composeApp/build.gradle.kts - Add dependency
3. initKoin.kt - Register DI module
4. BaseAppNavHost.kt - Wire navigation

Also generates:

• Living specification at .claude/docs/{feature}/spec.md
• Full build validation
