Avoid Private-Only Constructors

Classes with only private constructors cannot be instantiated outside their own scope, potentially making them dead code.

Why this matters

Classes with only private constructors cannot be instantiated outside their own scope, potentially making them dead code.

Side-by-side examples engineers can pattern-match during review.

Avoid

public class MyClass // Noncompliant: the class contains only private constructors
{
  private MyClass() { ... }
}

Prefer

public class MyClass // Compliant: the class contains at least one non-private constructor
{
  public MyClass() { ... }
}

Bad

public class MyClass // Noncompliant: the class contains only private constructors
{
  private MyClass() { ... }
}

Good

public class MyClass // Compliant: the class contains at least one non-private constructor
{
  public MyClass() { ... }
}

From the same buckets as this rule.

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Critical
Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
