/security - Security Audit Workflow

Dedicated security analysis for sensitive code.

When to Use

• "Security audit"
• "Check for vulnerabilities"
• "Is this secure?"
• "Review authentication code"
• "Check for injection attacks"
• Before handling auth, payments, user data
• After adding security-sensitive features

Agent Sequence

| # | Agent | Role | Output | |---|-------|------|--------| | 1 | **aegis** | Comprehensive security scan | Vulnerability report | | 2 | **arbiter** | Verify fixes, run security tests | Verification report |

Why Dedicated Security?

The `/review` workflow focuses on code quality. Security needs:

• Specialized vulnerability patterns
• Dependency scanning
• Secret detection
• OWASP Top 10 checks
• Authentication/authorization review

Execution

Phase 1: Security Audit

Task(
  subagent_type="aegis",
  prompt="""
  Security audit: [SCOPE]

  Scan for:

  **Injection Attacks:**
  - SQL injection
  - Command injection
  - XSS (Cross-Site Scripting)
  - LDAP injection

  **Authentication/Authorization:**
  - Broken authentication
  - Session management issues
  - Privilege escalation
  - Insecure direct object references

  **Data Protection:**
  - Sensitive data exposure
  - Hardcoded secrets/credentials
  - Insecure cryptography
  - Missing encryption

  **Configuration:**
  - Security misconfigurations
  - Default credentials
  - Verbose error messages
  - Missing security headers

  **Dependencies:**
  - Known vulnerable packages
  - Outdated dependencies
  - Supply chain risks

  Output: Detailed report with:
  - Severity (CRITICAL/HIGH/MEDIUM/LOW)
  - Location (file:line)
  - Description
  - Remediation steps
  """
)

Phase 2: Verification (After Fixes)

Task(
  subagent_type="arbiter",
  prompt="""
  Verify security fixes: [SCOPE]

  Run:
  - Security-focused tests
  - Dependency audit (npm audit, pip audit)
  - Re-check reported vulnerabilities
  - Verify fixes don't introduce regressions

  Output: Verification report
  """
)

Security Scopes

Full Codebase

User: /security
→ Scan entire codebase

Specific Area

User: /security authentication
→ Focus on auth-related code

Single File

User: /security src/api/auth.py
→ Deep dive on one file

Dependencies Only

User: /security --deps
→ Only dependency vulnerabilities

Example

User: /security the payment processing code
