+class classproperty(property):
+    """A decorator to define a read-only property at the class level.
+
+    This class extends the built-in `property` to allow a method to be accessed
+    as a property on the class itself, rather than an instance. This is useful
+    when you want a property-like syntax for methods that depend on the class
+    rather than any instance of the class.
+
+    Example:
+        class MyClass:
+            _value = 42
+
+            @classproperty
+            def value(cls):
+                return cls._value
+
+        print(MyClass.value)  # Outputs: 42
+
+    Methods:
+        __get__: Retrieves the value of the class property by calling the
+                 decorated method on the class.
+
+    Parameters:
+        fget (Callable[[type], Any]): A method that takes the class as an
+                                      argument and returns a value.
+
+    Raises:
+        AssertionError: If `fget` is not defined when `__get__` is called.
