             Review this pull request and provide feedback.
-            Post your feedback as a PR comment using `gh pr comment`.
 
-            When reviewing code, leave a general summary of the changes at the top of your comment and then evaluate the following areas:
+            If EXISTING_COMMENT_ID is set, update that comment using:
+              gh api repos/${{ github.repository }}/issues/comments/${{ steps.find-comment.outputs.comment_id }} -X PATCH -f body="<your review>"
+            Otherwise, create a new comment using:
+              gh pr comment ${{ github.event.pull_request.number }} --body "<your review>"
+
+            IMPORTANT GUIDELINES:
+            - Be direct and concise. Only mention issues that need attention.
+            - Start with a brief 1-2 sentence summary of the changes for other reviewers.
+            - Do NOT compliment the author or praise the code.
+            - If there are no significant issues, just say "No issues found." and nothing else.
+            - Focus only on actionable feedback.
+
+            Evaluate the following areas (only mention if there are issues):
