+Pattern: Redundant assignment of parameter property
+
+Issue: -
+
+## Description
+
+Constructor parameters with visibility modifiers (`public`, `private`, `protected`, or `readonly`) are automatically initialized as class properties. Explicitly assigning these parameters to their corresponding properties is redundant and unnecessary.
+
+## Examples
+
+Example of **incorrect** code:
+```typescript
+class Foo {
+  constructor(public name: unknown) {
+    this.name = name; // Unnecessary assignment
+  }
+}
+```
+
+Example of **correct** code:
+```typescript
+class Foo {
+  constructor(public name: unknown) {
+    // No assignment needed
+  }
+}
+```
