+# Detect Circular Reference in Task Dependencies
+
+## Overview
+
+This Script Include helps identify **circular dependencies** in task relationships within ServiceNow. Circular references can cause workflow issues, reporting errors, and logic failures in project management or task tracking modules.
+
+## What It Does
+
+- Traverses task dependencies recursively.
+- Detects if a task is indirectly dependent on itself.
+- Returns `true` if a circular reference is found, `false` otherwise.
+
+## Use Case
+
+Imagine Task A depends on Task B, and Task B depends on Task A. This creates a circular loop that can break automation or cause infinite recursion. This script helps prevent such configurations.
