Agents

Agents

Specialized sub-agents invoked by skills or commands to handle focused tasks.

New to agents? See Getting-Started for an introduction to how agents work.

Quick Reference

Agent	Purpose	Invoked By
data-layer-agent	Data layer (models, DataSource, Repository)	creating-kmp-feature
ui-layer-agent	UI layer (UiModel, ViewModel, Screens)	creating-kmp-feature
integration-agent	4 integration points + spec generation	creating-kmp-feature
test-fixtures	Generates domain + UI fixtures	/feature-test
test-datasource	MockEngine DataSource tests	/feature-test
test-repository	Mokkery Repository tests	/feature-test
test-viewmodel	Turbine ViewModel tests	/feature-test
test-ui	Compose UI tests (ScreenRoot)	/feature-test
test-integration	E2E integration tests	/feature-test
code-reviewer	Architecture compliance review	/feature-review

Feature Development Agents

data-layer-agent

Implements the data layer for KMP features.

Invoked by: creating-kmp-feature skill (Phase 3)

Generates:

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

See: Data-Layer-Agent

ui-layer-agent

Implements the UI layer for KMP features.

Invoked by: creating-kmp-feature skill (Phase 3)

Generates:

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

See: UI-Layer-Agent

---

integration-agent

Completes the 4 integration points and generates living specification.

Invoked by: creating-kmp-feature skill (Phase 3, after data + ui)

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

See: Integration-Agent

Testing Agents

Testing agents are spawned by the Feature-Test command to generate comprehensive test coverage.

See: Testing-Agents | Feature-Test

Code Quality Agents

code-reviewer

Reviews feature implementations against architecture rules.

Invoked via: /feature-review {featurename} command

What it validates:

10 Critical Rules:

1. Interface + Impl pairs for DataSource/Repository
2. Either for all fallible operations
3. setState { } for state updates (never direct assignment)
4. 4-state UI: Uninitialized/Loading/Success/Failed
5. X-components only (no Material3)
6. ImmutableList for collections
7. Callback parameters for navigation
8. Lowercase packages (no hyphens/underscores)
9. @Serializable on all models
10. Type-safe navigation routes

4 Integration Points:

1. settings.gradle.kts includes module
2. composeApp/build.gradle.kts has dependency
3. initKoin.kt registers DI module
4. BaseAppNavHost.kt wires navigation
