+- Contents:
+  - MITRE ATT&CK framework analysis (11+ techniques verified)
+  - Detailed security findings per attack vector
+  - Input validation assessment

+
+## 🎯 Quick Summary
+
+**Files Scanned**: 2 shell scripts (434 lines total)
+- `.github/skills/graudit-security-scan/graudit-wrapper.sh`
+- `.github/skills/graudit-security-scan/graudit-deep-scan.sh`
+
+**Security Status**: 🟢 **SAFE**
+
+### Findings Overview
+```
+🔴 CRITICAL:  0 issues
+🟠 HIGH:      0 issues
+🟡 MEDIUM:    0 issues
+🟢 LOW:       6 issues (code quality only)
+ℹ️  INFO:     4 issues (style suggestions)
+```
+
+### Malicious Code Check Results
+✅ No reverse shells or backdoors  
+✅ No data exfiltration attempts  
+✅ No credential theft patterns  
+✅ No obfuscated payloads  
+✅ No persistence mechanisms  
+✅ No privilege escalation attempts  
+✅ No system destruction code  
+✅ No suspicious network activity  
+
+### Tools Used
+- ✅ **ShellCheck v0.9.0** - Shell script static analysis
+- ❌ **Bandit** - Not installed (not needed - no Python files)
+- ❌ **GuardDog** - Not installed (not needed - no dependencies)
+- ❌ **Graudit** - Not installed (scripts wrap this tool)
+
+## 🔍 Key Takeaways
+
+1. **Both scripts are secure and safe to use**
+2. All ShellCheck warnings are minor code quality issues (unused variables)
+3. No security vulnerabilities detected
+4. Scripts serve their legitimate purpose as graudit security scanning wrappers
+5. Proper input validation and error handling implemented
+6. No external network operations or data transmission
+
+## 📋 Recommendations
+
+### Security
+**✅ No action required** - Scripts are secure.
+
+### Code Quality (Optional)
+- Remove unused variables (OUTPUT_FORMAT, exit_code, BLUE, LANGUAGE_DBS, OTHER_DBS)
+- Remove or implement unused `count_findings()` function
+- Fix SC2155 warning by splitting variable declaration
+
+## 🔄 Next Review
+
+Perform security scan when:
+- Scripts are modified or updated
+- New code is added to the repository
+- Graudit tool is installed (for self-testing)
