Type Safety

Purpose: Use type systems to catch errors at compile/analysis time rather than runtime. Goal: Prevent null errors, type mismatches, and invalid states. Note: For implementation, see C# Development or Python Development.

When to Use This Skill

• Adding type annotations to existing code
• Implementing nullable reference types
• Building type-safe APIs with value objects
• Configuring static analysis tools
• Designing strongly-typed data transfer objects

Prerequisites

• Language with type system support
