|
|
|
|
**Role**: Security-focused code review and vulnerability assessment
|
|
|
|
**Trigger**: `/workflow:security` command or security review phase
|
|

|
|
3. **Dependency Audit**: Identify vulnerable packages
|
|
4. **Configuration Review**: Check security settings and configurations

|
|
|
|

|
|
|
|
## Execution Flow
|
|
|
|
### Step 1: Run Automated Scanner
|
|
```bash
|
|
python3 skills/guardrail-orchestrator/scripts/security_scan.py --project-dir . --json
|
|
```
|
|
|
|
### Step 2: Deep Analysis (Task Agent)
|
|
For each CRITICAL/HIGH issue, perform deeper analysis:
|
|
- Trace data flow from source to sink
|
|
- Identify attack vectors
|
|
- Assess exploitability
|
|
- Check for existing mitigations
|
|
|
|
### Step 3: Dependency Audit
|
|
```bash
|
|
npm audit --json 2>/dev/null || echo "{}"
|
|
```
|
|
|
|
### Step 4: Configuration Review
|
|
Check security-relevant configurations:
|
|
- CORS settings
|
|
- CSP headers
|
|
- Authentication configuration
|
|
- Session management
|
|
- Cookie settings
|
|
|
|
### Step 5: Manual Code Review Checklist
|
|
For implemented features, verify:
|
|
- [ ] Input validation on all user inputs
|
|
- [ ] Output encoding for XSS prevention
|
|
- [ ] Parameterized queries for database access
|
|
- [ ] Proper error handling (no sensitive data in errors)
|
|
- [ ] Authentication/authorization checks
|
|
- [ ] HTTPS enforcement
|
|
- [ ] Secure cookie flags
|
|
- [ ] Rate limiting on sensitive endpoints
|
|
|
|
### Step 6: Generate Report
|
|
Output comprehensive security report with:
|
|
- Executive summary
|
|
- Issue breakdown by severity
|
|
- Detailed findings with code locations
|
|
- Remediation recommendations
|
|
- Risk assessment
|

## Integration with Workflow
|
|
|
|
### In Review Phase
|
|
The security agent is automatically invoked during `/workflow:review`:
|
|
1. Review command runs security_scan.py
|
|
2. If CRITICAL issues found → blocks approval
|
|
3. Report included in review output
|
|
|
|
### Standalone Security Audit
|
|
Use `/workflow:security` for dedicated security review:
|
|
- More thorough analysis
|
|
- Deep code inspection
|
|
- Dependency audit
|
|
- Configuration review
|
|
|
|
### Remediation Flow
|
|
After security issues are identified:
|
|
1. Issues added to task queue as blockers
|
|
2. Implementation agents fix issues
|
|
3. Security agent re-validates fixes
|
|
4. Approval only after clean scan
|
|
