+            You are running a full-codebase security scan in GitHub Actions.
+
+            First, read the prompt file at:
+            ${{ steps.vars.outputs.prompt_path }}
+
+            Treat that file as the authoritative security-review instruction set.
+
+            Scan the checked-out repository as a whole codebase.
+            Do not modify files.
+            Do not create commits.
+            Do not open pull requests.
+            Do not post GitHub comments.
+            Do not create GitHub issues.
