How does this skill prevent architectural drift?

It provides automated validation and guidance when creating or moving files, ensuring developers and AI models follow established naming and placement conventions.

Why are logic-heavy route files prohibited in the app/ directory?

The app/ directory is reserved for Expo Router navigation. Keeping these files as thin wrappers ensures that the core logic resides within organized feature modules.

What is the Container/View pattern enforced by this skill?

It separates business logic and state management (Container) from pure UI presentation (View) to improve testability and maintainability.

Where should test files be placed according to this skill?

All unit and spec tests must be placed in a dedicated __tests__/ subdirectory located within the same folder as the file being tested.

Mobile Development

Enforces project-specific directory standards and architectural patterns for Expo and React Native development.

This skill acts as an automated governance layer for your codebase, ensuring that all new files and directories adhere to a strict organizational schema. It specifically validates the placement of feature modules, shared components, and test files while mandating the Container/View design pattern for components and screens. By preventing architectural drift and ensuring Expo Router files remain thin wrappers, it maintains a clean, scalable, and predictable project structure suitable for professional AI-assisted development.
