+            Focus on actionable VoScript risks:
+            - Privacy and security leaks
+            - Model lifecycle races and GPU/CPU fallback behavior
+            - HTTP API compatibility
+            - Regression-test coverage
+            - Synchronized English/Chinese documentation
+
+            The PR branch is already checked out in the current working directory.
+            Post feedback only through the official Claude Code Action GitHub integration.
+            Do not use the GitHub CLI and do not use a user-owned GitHub token.
+            If the official Claude GitHub App integration is unavailable, fail instead of posting as the repository owner.
+            If there are no actionable findings, post the standard no-findings confirmation through the action integration.
+            Avoid formatting-only comments.
