 ## Style Guidelines
 - Use double quotes for strings (we're a SQL Server module)
 - Array declarations should be on multiple lines:

+### Parameter & Variable Naming Rules
+- Use direct parameters for 1-2 parameters
+- Use `$splat<Purpose>` for 3+ parameters (never plain `$splat`)

+```powershell
+# Direct parameters
+$ag = Get-DbaLogin -SqlInstance $instance -Login $loginName

+    Confirm = $false
+}
+$primaryAg = New-DbaAvailabilityGroup @splatPrimary

+### Unique names across scopes

+- Use unique, descriptive variable names across scopes to avoid collisions
+- Play particlar attention to variable names in the BeforeAll
