+            Review this PR for:
+            - Security issues (especially in launcher scripts)
+            - Logic errors and edge cases
+            - Error handling gaps
+            - JavaScript/Node.js best practices
+            - Cross-platform compatibility (Windows/Linux/macOS)
+            - Adherence to existing code patterns in the repo
+
+            Focus on substantive issues. Skip minor style comments that linters would catch.
