Upon reviewing the code changes, here are my comments:

• The code looks well organized and seems to be following the best practices.
• I recommend adding more descriptive comments to explain the purpose of the code and its functionality.
• The patch_output variable is used multiple times in the code. Ensure that it is correctly named throughout.
• Make sure that all the environment variables are correctly named and are used in the correct format.
• It would be helpful to add a comment describing the purpose of the OpenAI API Keys.

Overall, these changes look good. Here are some notes:

• It looks like the second patch is updating the OpenAI Review Workflow action to use a different repository. Make sure that this new repository is properly configured for use with your project.
• Check for typos in repeating variables, such as GIT_PATCH_OUTPUT.
• Make sure that all the required secrets (GITHUB_TOKEN, OPENAI_API_KEY, OPENAI_ORG_KEY) are set up properly.
