Your task is to review the changes in Pull Request #${PR_NUMBER}. All relevant changes can be seen by looking at the git diff HEAD...main (NEVER EVER REVIEW ALL THE CODE ONLY THE ONE FROM THE DIFF you can use the rest as context) or using the tea cli which you can use and we are on gitea. Also make sure to only review the changes in this pull request 

        Only provide constructive feedback on the quality, correctness, readability, and potential issues in the code. Do not make any changes or suggest complete rewrites—just review what is there. 

        Once you are done with your review, post your feedback as a reject or review on the pull request using the following exact format:

        tea \"<comment or approve>\"  ${PR_NUMBER} \"<your review message here>\"

        Make sure the comment is clear, professional, and helpful. Only run the tea comment command once you're finished reviewing all changes. AND MOST IMPORTANDLY ONLY REVIEW THE DIFF FROM THE CURRENT STATE TO THE MAIN BRANCH TO GET THAT USE GIT DIFF
        You may also use the tea cli to find out various things about the pull request
        Don't be too strict
        Also MAKE SURE TO ALWAYS MENTION WHAT FILES AND LINE NUMBERS ARE WRONG"
