+=================================
+
+Detect redundant parentheses.
+
+When modifying the code, one often forgets to remove the corresponding parentheses.
+This results in overly lengthy code. When the expression is complex, finding
+the matching parentheses becomes particularly difficult.
+
+Example
+-------
+
+.. code-block:: c++
+
+  (1);
+  ((a + 2)) * 3;
+  (a);
+  ("aaa");
+
+Currently this check does not take into account the precedence of operations.
+Even if the expression within the parentheses has a higher priority than that
+outside the parentheses, in other words, removing the parentheses will not
+affect the semantic.

Not very sure about this one, but `semantics` usually used in plural?
