@AlSweigart currently my workflow is to let it make a plan than to let it create a test which i review rigorous the diff
Then i let it implement the code and let it run all the tests
Than I check the diff of the code but not as rigorous as the test code diff
So with linting tools which are integrated in the tests and report the llm changes the code according to the text output

Is it perfect. No. Can I do it perfect. No. But it is a reliable and consistent process to create testing tools and other little helpers.
