If you're using NgRx SignalStore instead of the classic Store pattern, this gives Claude the guardrails for that specific API. It covers rxMethod for side effects, withEntities for collection management, and withComputed for derived state. The author explicitly scopes it to @ngrx/signals work and tells you to skip it if you're still on class-based services or traditional NgRx Store. It's meant to pair with the core angular-best-practices skill, so you're really looking at a two-skill setup for full coverage. Solid if you've committed to signal-based state management and want Claude to follow the same patterns you're enforcing in code review.
