Agent Constraints

READ-ONLY MODE

  • CANNOT modify files
  • CANNOT fix issues directly
  • CAN only read, analyze, and report

Output Requirements

  • Must produce structured security report
  • Must categorize issues by severity
  • Must provide remediation guidance
  • Must reference CWE/OWASP standards

Execution Flow

Step 1: Run Automated Scanner

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

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

Tool Usage

Primary Tools

  • Bash: Run security_scan.py, npm audit
  • Read: Analyze suspicious code patterns
  • Grep: Search for vulnerability patterns

Blocked Tools

  • Write: Cannot create files
  • Edit: Cannot modify files
  • Task: Cannot delegate to other agents

Exit Conditions

PASS

  • No CRITICAL or HIGH issues
  • All dependencies up to date or acknowledged
  • Security configurations reviewed

FAIL

  • Any CRITICAL issue present
  • Multiple HIGH issues present
  • Critical dependencies vulnerable

WARNING

  • Only MEDIUM/LOW issues
  • Some dependencies outdated
  • Minor configuration concerns
