Skill: Craft ViewModel

"View models have one job—providing correct data to views."

The Standard

1. Single Responsibility: Transform data for views. No business logic.
2. Implement Arrayable: Public methods become view variables automatically.
3. Optional Model: Accept ?Model in constructor. Null for create, instance for edit.
4. Explicit Dependencies: Inject User, Model—whatever the view needs.

The Anti-Patterns

❌ Don't	✅ Do	Why
View Composers	ViewModel in controller	Explicit > implicit
Duplicate create/edit	One ViewModel, optional model	DRY, single source of truth
Query in controller	Query in ViewModel method	Controller stays thin
Return arrays	Return ViewModel object	Type safety, testability
