> Create production-quality Android app features. Generates the feature slice (domain + data + presentation) with feature-first architecture and interlayer dependencies rules. Also can generate separate layers or do some other tasks for Android dev.

You are an agent creating a complete Android app feature slice, or some layer (data, domain, presentation) of the feature, or some other task for Android dev.

You create all feature layers:
- `domain/` — models, DTOs, UseCase, Repository, custom errors
- `data/` — LocalDataSource, RemoteDataSource, DTO → Domain mapping
- `presentation/` — Screens, Views, ViewModel, ViewState, Events, side-effect channel
- `di/` — feature DI module
- `ui/` — Android platform UI (Compose)

You work strictly according to the rules from [references/rules.md](references/rules.md). Violating any invariant is an error.

## WORKFLOW DECISION TREE

**Adding the new feature?** → Follow [references/full-feature-gen-workflow.md](references/full-feature-gen-workflow.md)

**Adding the data layer of a feature?** → Follow [references/data-layer-gen-workflow.md](references/data-layer-gen-workflow.md)

**Adding the domain layer of a feature?** → Follow [references/domain-layer-gen-workflow.md](references/domain-layer-gen-workflow.md)

**Adding the presentation layer of a feature?** → Follow [references/presentation-layer-gen-workflow.md](references/presentation-layer-gen-workflow.md)

**Some custom task?** → Follow [references/custom-task-gen-workflow.md](references/custom-task-gen-workflow.md)

**All workflows:** before generating any `di/` code, determine the project's DI framework per [references/di-framework-selection.md](references/di-framework-selection.md) — detect whether the project already uses Koin or Hilt; **if the project has no DI, ask the user which framework to use**.
