## Description
'**Intent**: Identify when primitive types (strings, numbers) are used to represent domain concepts that should be objects.

**Context**: You're passing around primitive types like strings for phone numbers, email addresses, or money. Validation and behavior related to these concepts is scattered throughout the codebase.

**Solution**: Create small classes or objects to represent these domain concepts. Move validation and related behavior into these classes.'



## Use Cases
Use when primitives are used for domain concepts that have behavior or validation requirements.
