+=====================================
+
+Replace comparisons between signed and unsigned integers with their safe
+``std::cmp_*`` alternative.
+
+Examples of fixes created by the check:
+
+.. code-block:: c++
+
+    uint func(int bla)
+    {
+        uint result;
+        if (result == bla)
+            return 0;
+
+        return 1;
+    }
+
+becomes
+
+.. code-block:: c++
+
+    #include <utility>
+
+    uint func(int bla)
+    {
+        uint result;
+        if (std::cmp_equal(result, bla))
+            return 0;
+
+        return 1;
+    }
+
