@azure-tools/typespec-azure-resource-manager/improper-subscription-list-operation

Tenant and Extension resources should not define a list by subscription operation.

These resource types are not scoped to a subscription, so listing them by subscription is not appropriate.

Impact

• Area: API

Likely a modeling error - only subscription-based resources should have subscription list operations.

❌ Incorrect

@tenantResource
model FooResource is ProxyResource<FooProperties> {
  ...ResourceNameParameter<FooResource>;
}

@armResourceOperations(FooResource)
interface FooResources {
  listBySubscription is ArmListBySubscription<FooResource>;
}

✅ Correct

@tenantResource
model FooResource is ProxyResource<FooProperties> {
  ...ResourceNameParameter<FooResource>;
}

@armResourceOperations(FooResource)
interface FooResources {
  get is ArmResourceRead<FooResource>;
}

Suppression

Suppress per the RPC guidelines. Ensure tenant resources have only a tenant list, and use the standard resource operations.
