Platform Separation Validator

Overview

This skill enforces the critical platform separation architecture that prevents Node.js dependencies in React Native code and ensures security-critical operations (cryptography, authentication, data encryption) remain exclusively server-side. The skill validates import paths, detects violations, and guides developers toward compliant patterns.

Core Principle: Client (React Native) and Server (NestJS) have fundamentally different capabilities. Mixing them causes bundle failures, security vulnerabilities, and runtime crashes.

When to Use This Skill

Use this skill when:

• Reviewing code changes for platform separation violations
• Implementing new features that span client and server
• Debugging import errors or "Cannot find module" issues
• Refactoring shared libraries for platform compatibility
• Auditing codebase for separation compliance (100% compliance required)
• Creating new shared libraries that need client/server separation
• Investigating bundle size issues or Node.js dependency leaks
