+- If applicable, attempt to reproduce vulnerabilities (in PoC) and provide remediation guidance
+
+Notes for Strix:
+- Use `--scan-mode quick` for fast checks or `--scan-mode standard` for deeper analysis
+- Use `--instruction-file` with this file when invoking strix CLI
+
+Do NOT run active exploitation against third-party services. Only analyze code in-repo.
