## When to Apply

- Creating or modifying SignalStore-based state management
- Integrating RxJS side effects with `rxMethod`
- Managing collections with `withEntities`

## Rules

| Rule | Impact | Description |
|------|--------|-------------|
| Use rxMethod for RxJS Integration | MEDIUM | Debounce, switchMap, and other RxJS operators in stores |
| Use SignalStore for Shared State | HIGH | Signal-based reactivity without full NgRx overhead |
| Use withComputed for Derived State | MEDIUM | Centralized memoized derivation logic |
| Use withEntities for Collections | MEDIUM | O(1) lookups and standardized CRUD operations |
