/security - Multi-Agent Security Audit (v3.0)

Comprehensive security audit using Codex GPT-5 for primary analysis and MiniMax for second opinion validation.

v2.88 Key Changes (MODEL-AGNOSTIC)

  • Model-agnostic: Uses model configured in ~/.claude/settings.json or CLI/env vars
  • No flags required: Works with the configured default model
  • Flexible: Works with GLM-5, Claude, Minimax, or any configured model
  • Settings-driven: Model selection via ANTHROPIC_DEFAULT_*_MODEL env vars

Agent Teams Integration (v2.88)

Optimal Scenario: Integrated (Agent Teams + Custom Subagents)

This skill uses the INTEGRATED approach combining Agent Teams coordination with Custom Subagent specialization.

Why Scenario C for This Skill

  • Parallel security scanning requires coordinated multi-agent analysis across different vulnerability types
  • Quality gates (TeammateIdle, TaskCompleted) ensure all security findings are properly addressed
  • Specialized ralph-reviewer agents for vulnerability detection, ralph-coder for remediation
  • Shared task list tracks findings and fix assignments
  • Multi-phase workflow (scan -> prioritize -> fix -> verify) benefits from team coordination

Configuration

  1. TeamCreate: Create team "security-audit-${TARGET}" on security invocation
  2. TaskCreate: Create tasks for analysis, prioritization, and remediation phases
  3. Spawn: Use ralph-reviewer for scanning, ralph-coder for fixes
  4. Hooks: TeammateIdle + TaskCompleted for security validation
  5. Coordination: Shared task list at ~/.claude/tasks/{team}/

Workflow Pattern

TeamCreate(team_name, description)
  → TaskCreate(scan_task, "Security vulnerability analysis")
  → Task(subagent_type="ralph-reviewer", team_name) for parallel scanning
  → TaskCreate(fix_task, "Apply security fixes")
  → Task(subagent_type="ralph-coder", team_name) for remediation
  → TaskUpdate(status="completed") as findings are resolved
  → Hooks validate security standards
  → VERIFIED_DONE when all critical/high findings fixed

Automatic Team Creation

When /security is invoked on a directory with multiple files, it automatically:

# 1. Create security audit team
TeamCreate(team_name="security-audit-${TARGET}", description="Security analysis and fixes")

# 2. Spawn specialized teammates
Task(subagent_type="ralph-reviewer", team_name="security-audit-${TARGET}")  # Analyze vulnerabilities
Task(subagent_type="ralph-coder", team_name="security-audit-${TARGET}")     # Apply security fixes

Teammate Roles

Agent Role Model Tasks
ralph-reviewer Security analysis, vulnerability detection Model from settings - CWE vulnerability scan- OWASP Top 10 check- Input validation review- Remediation guidance
ralph-coder Security fix implementation Model from settings - Apply security patches- Add validation- Implement secure patterns- Add security tests
team-lead Coordination Opus - Assign tasks- Aggregate findings- Validate remediation

Coordination via Shared Task List

# Team lead creates coordinated tasks
TaskCreate:
  subject: "Analyze ${TARGET} for security vulnerabilities"
  description: |
    ralph-reviewer: Perform security audit on assigned files
    Focus on:
    - CWE vulnerabilities (prioritize High/Critical)
    - OWASP Top 10 risks
    - Input validation issues
    - Authentication/authorization flaws
    - SQL/Command/XSS injection vectors

    Output format per file:
    {
      "findings": [
        {
          "severity": "CRITICAL|HIGH|MEDIUM|LOW",
          "cwe": "CWE-XXX",

          "remediation": "How to fix",
          "references": ["URL1", "URL2"]
        }
      ]
    }

TaskCreate:
  subject: "Fix CRITICAL/HIGH security findings in ${TARGET}"
  description: |
    ralph-coder: Implement security fixes
    - Read findings from ralph-reviewer
    - Apply remediation steps
    - Add input validation
    - Implement secure patterns
    - Add security tests
    - Run quality gates after each fix

Quality Gates Integration

Agent Teams hooks automatically validate security fixes:

# Hooks run automatically (configured in ~/.claude/settings.json)
TeammateIdle  → teammate-idle-quality-gate.sh    # Before going idle
TaskCompleted → task-completed-quality-gate.sh   # Before marking complete

# Security-specific quality checks:
# 1. No hardcoded secrets
# 2. Proper input validation
# 3. No console.log with sensitive data
# 4. All CRITICAL/HIGH findings fixed

Example Team-Based Security Audit

# User invokes /security on large codebase
ralph security src/

# Behind the scenes:
# 1. Team created: "security-audit-src"
# 2. Files split among 3 ralph-reviewer agents by module
# 3. Each reviewer performs security audit in parallel
# 4. Team lead aggregates findings, removes duplicates
# 5. CRITICAL/HIGH findings assigned to ralph-coder agents
# 6. Quality gates run automatically after each fix
# 7. Final verification scan confirms all vulnerabilities resolved

# Time savings: 3x faster than sequential audit
# Coverage: Parallel agents catch different vulnerability types

Multi-Model Second Opinion (Optional)

For critical security audits, combine Agent Teams with multi-model validation:

# Primary audit: ralph-reviewer (model from settings)
# Second opinion: Additional reviewer with different model
Task(subagent_type="ralph-reviewer", model="opus", team_name="security-audit-${TARGET}")

Overview

The /security command performs a thorough security audit of your codebase, checking for:

  • CWE (Common Weakness Enumeration) vulnerabilities
  • OWASP Top 10 security risks
  • Input validation and sanitization issues
  • Authentication and authorization flaws
  • Cryptographic weaknesses
  • Injection vulnerabilities (SQL, Command, XSS, etc.)
  • Path traversal and file handling risks
  • Race conditions and TOCTOU bugs
  • Insecure defaults and misconfigurations

Results are returned in structured JSON format with severity ratings, CWE references, and remediation guidance.

When to Use

Trigger /security when:

  • Adding new features that handle user input
  • Before merging security-critical changes
  • After dependency updates that may introduce vulnerabilities
  • Implementing authentication or authorization logic
  • Working with file operations, shell commands, or network requests
  • Preparing for production deployment
  • Conducting periodic security reviews

Task Tool Invocation

Primary Security Audit (Codex GPT-5)

Task:
  subagent_type: "security-auditor"
  model: "sonnet"  # Sonnet manages the Codex CLI call
  run_in_background: true
  description: "Codex: Primary security audit"
  prompt: |
    Execute via Codex CLI for security analysis:
    cd /absolute/path/to/project && codex exec -m gpt-5.2-codex "
    Perform comprehensive security audit on: <path>

    Check for:
    1. CWE vulnerabilities (prioritize High/Critical)
    2. OWASP Top 10 risks
    3. Input validation issues
    4. Authentication/authorization flaws
    5. SQL/Command/XSS injection vectors
    6. Path traversal (CWE-22, CWE-59)
    7. Command injection (CWE-78)
    8. Insecure crypto (CWE-327, CWE-338)
    9. Race conditions (CWE-362, CWE-367)
    10. Information disclosure (CWE-200, CWE-209)

    Output format: JSON with structure:
    {
      'findings': [
        {

      }
    }
    "

    Apply Ralph Loop: iterate until audit complete and all findings validated.

Secondary Validation (MiniMax Second Opinion)

Task:
  subagent_type: "minimax-reviewer"
  model: "sonnet"  # Sonnet manages the mmc CLI call
  run_in_background: true
  description: "MiniMax: Security second opinion"
  prompt: |
    Execute via MiniMax CLI for independent security validation:
    mmc --query "
    Perform independent security review on: <path>

    Focus on vulnerabilities Codex might have missed:
    1. Subtle logic flaws in authentication
    2. Business logic vulnerabilities
    3. Race conditions in concurrent code
    4. Insecure defaults and misconfigurations
    5. Complex injection chains

    Cross-validate Codex findings and identify additional issues.
    Use same JSON format as Codex for consistency.

# Security Audit Report

**Date:** 2025-01-04
**Target:** src/
**Tools:** Codex GPT-5 + MiniMax M2.1

## Summary

- **Total Findings:** 2
- **Critical:** 1
- **High:** 1
- **Medium:** 0
- **Low:** 0

## Findings

### [CRITICAL] Command Injection in file upload handler

**CWE:** CWE-78
**OWASP:** A03:2021-Injection
**File:** src/upload/handler.ts:145

**Vulnerable Code:**
```typescript
// UNSAFE - allows command injection
execSync(`convert ${filename} output.png`)

Description: User-supplied filename passed to shell without sanitization, allowing arbitrary command execution.

Remediation: Use execFile with array arguments:

// SAFE - no shell interpolation
import { execFileNoThrow } from '../utils/execFileNoThrow.js'
await execFileNoThrow('convert', [filename, 'output.png'])

## Security Considerations

### For the Security Command Itself

1. **Safe Code Analysis** - The security audit reads code but never executes it
2. **Sensitive Data Handling** - Reports may contain code snippets with secrets; handle with care
3. **False Positives** - Manual review required; automated tools may flag benign patterns
4. **Scope Limitation** - Static analysis only; cannot detect runtime vulnerabilities
5. **Tool Trust** - Codex and MiniMax are third-party services; do not send proprietary code if restricted

### CWE Categories Checked

| Category | CWEs | Description |
|----------|------|-------------|
| **Injection** | CWE-78, CWE-89, CWE-79 | Command, SQL, XSS injection |
| **Path Traversal** | CWE-22, CWE-59 | File access outside allowed directories |
| **Input Validation** | CWE-20, CWE-116 | Improper input sanitization |
| **Authentication** | CWE-287, CWE-307 | Broken authentication, brute force |
| **Authorization** | CWE-284, CWE-862 | Missing access controls |
| **Cryptography** | CWE-327, CWE-338 | Weak crypto, insecure RNG |
| **Race Conditions** | CWE-362, CWE-367 | TOCTOU, concurrent access |
| **Information Disclosure** | CWE-200, CWE-209 | Leaking sensitive data |
| **Resource Management** | CWE-400, CWE-770 | DoS, resource exhaustion |

### OWASP Top 10 Mapping

| OWASP Category | CWE Examples | Priority |
|----------------|--------------|----------|
| A01:2021-Broken Access Control | CWE-22, CWE-862 | High |
| A02:2021-Cryptographic Failures | CWE-327, CWE-338 | High |
| A03:2021-Injection | CWE-78, CWE-89, CWE-79 | Critical |
| A04:2021-Insecure Design | CWE-840 | Medium |
| A05:2021-Security Misconfiguration | CWE-16 | Medium |
| A06:2021-Vulnerable Components | CVE references | High |
| A07:2021-Authentication Failures | CWE-287, CWE-307 | Critical |

| A09:2021-Logging Failures | CWE-778 | Low |
| A10:2021-SSRF | CWE-918 | Medium |

## Integration with Quality Gates

The security audit integrates with `ralph gates`:

```bash
# Run security audit as part of quality gates
ralph gates

# Quality gates automatically include:
# 1. Language-specific linting (9 languages)
# 2. Security audit (if security-critical files changed)
# 3. Test coverage validation
# 4. Git safety checks

Gate Failure Criteria:

  • Any CRITICAL severity finding → BLOCK merge
  • 2+ HIGH severity findings → BLOCK merge
  • MEDIUM findings → Warning (review required)
  • LOW findings → Info only

Related Commands

Command Purpose Use Case
/security Full security audit Pre-merge security review
/adversarial Adversarial spec refinement Critical features (complexity >= 7)
/bugs Bug hunting Functional issues, not security
/security-loop Iterative security fixes Apply fixes until audit passes
/code-review General code review Quality, not security-focused
ralph gates Quality gates Pre-commit validation

Examples

Example 1: Pre-Merge Security Review

# Scenario: About to merge authentication feature
ralph security src/auth/

# Output: JSON report with 3 findings
# - CRITICAL: Hardcoded JWT secret (CWE-798)
# - HIGH: Missing rate limiting (CWE-307)
# - MEDIUM: Weak password requirements (CWE-521)

Example 2: Dependency Update Review

# Scenario: Updated Express from 4.17 to 4.18
ralph security src/api/

# Output: No new vulnerabilities introduced
# - Validates middleware security
# - Checks request parsing
# - Reviews error handling

Example 3: File Upload Security

# Scenario: Implementing file upload feature
ralph security src/upload/

# Output: 2 CRITICAL findings
# - Command injection in filename handling (CWE-78)
# - Path traversal in storage location (CWE-22)

Example 4: Task Tool Invocation with Second Opinion

# Primary audit
Task:
  subagent_type: "security-auditor"
  model: "sonnet"
  run_in_background: true
  description: "Codex: Security audit of auth module"
  prompt: |
    codex exec -m gpt-5.2-codex "
    Security audit: src/auth/
    Focus on authentication bypasses, session hijacking, and credential storage.
    JSON output with CWE/OWASP references.
    "

# Second opinion
Task:
  subagent_type: "minimax-reviewer"
  model: "sonnet"
  run_in_background: true
  description: "MiniMax: Validate Codex findings"
  prompt: |
    mmc --query "
    Independent security review: src/auth/
    Cross-validate Codex findings and find missed issues.
    Same JSON format.
    "

Example 5: Integration with Worktree Workflow

# Create isolated worktree for security fixes
ralph worktree "fix-security-findings"

# Run security audit in worktree
cd ~/worktrees/fix-security-findings
ralph security src/

# Fix findings, then PR review with multi-agent validation
ralph worktree-pr fix-security-findings

Anti-Patterns

  • Don't skip security audits for "quick fixes" - Small changes can introduce big vulnerabilities
  • Don't ignore LOW severity findings - Multiple LOW can combine to HIGH impact
  • Don't trust static analysis alone - Manual review + penetration testing required
  • Don't audit third-party code - Focus on your code; use dependency scanners for libraries
  • Don't send proprietary code to external services - Check company policies first

Advanced Usage

Custom Security Rules

# Audit with custom CWE focus
ralph security src/ --cwe CWE-78,CWE-89,CWE-79

# Audit with severity threshold
ralph security src/ --min-severity HIGH

# Audit with specific OWASP category
ralph security src/ --owasp A03:2021-Injection

Continuous Security Monitoring

# Add to CI/CD pipeline
name: Security Audit
on: [push, pull_request]
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: ralph security . --output security-report.json
      - run: |
          if jq -e '.summary.critical > 0 or .summary.high > 1' security-report.json; then
            echo "Security audit failed"
            exit 1
          fi

Security Loop Pattern

# Iterate until all findings resolved
ralph loop --security "Fix security findings in src/auth/"

# The loop will:
# 1. Run security audit
# 2. Apply fixes
# 3. Re-audit
# 4. Repeat until clean (max 15 iterations)
