+This codemod replaces all `tempfile.mktemp` calls to the more secure `tempfile.mkstemp`.
+
+The Python [tempfile documentation](https://docs.python.org/3/library/tempfile.html#tempfile.mktemp) is explicit
+that `tempfile.mktemp` should be deprecated to avoid an unsafe and unexpected race condition.
+The changes from this codemod look like this:
+
+
+```diff
+  import tempfile
+- tempfile.mktemp(...)
++ tempfile.mkstemp(...)
+```
+
