             ## IMPORTANT: Writing the Review
-            After completing your analysis, write the final review markdown to `${{ env.REVIEW_OUTPUT_FILE }}`.
+            After completing your analysis, use the `Write` tool to write the final review markdown to `${{ env.REVIEW_OUTPUT_FILE }}`.
+            Do NOT use `Edit` tool — use `Write` tool directly to create the file in one shot.
             Do NOT post any GitHub comments yourself. The workflow will publish the saved file.
+            Do NOT modify any source code files — this is a READ-ONLY review.
 
             End your review with:
             > 🤖 Reviewed by `${{ env.REVIEW_MODEL }}`
 
             IMPORTANT RULES:
-            - Overwrite `${{ env.REVIEW_OUTPUT_FILE }}`
+            - Use `Write` tool to overwrite `${{ env.REVIEW_OUTPUT_FILE }}` with the complete review
             - Do NOT use shell operators like || or && in bash commands
             - Do NOT use heredoc (<<) syntax in bash commands
             - Use simple, single-purpose bash commands only
