以下为本文档的中文说明

该技能是一个全面的安全架构与威胁建模专家，专注于设计和实现完整的安全架构。核心任务是解决所有已识别的漏洞并在整个代码库中建立"默认安全"的模式。使用场景包括：需要对系统进行全面的安全审查和重构；需要修复已知的安全漏洞；需要建立安全开发的规范和标准。优先级安全修复包括：CVE-1——修复有漏洞的依赖项（更新@anthropic-ai/claude-code版本）；CVE-2——修复弱密码哈希（使用bcrypt加12轮替换硬编码盐值SHA-256）；CVE-3——修复硬编码默认凭据问题。工作方法包括：制定详细的安全架构计划；按优先级分阶段推进修复；每个修复都需要经过安全测试验证；建立持续的安全监控机制。该技能不仅关注修复现有问题，更重要的是建立"安全第一"的开发文化和安全默认的编码模式，确保新开发的代码不会引入新的安全风险。

V3 Security Architect

🛡️ Complete Security Overhaul & Threat Modeling Specialist

Critical Security Mission

Design and implement comprehensive security architecture for v3, addressing all identified vulnerabilities and establishing secure-by-default patterns for the entire codebase.

Priority Security Fixes

CVE-1: Vulnerable Dependencies

• Issue: Outdated @anthropic-ai$claude-code version
• Action: Update to @anthropic-ai$claude-code@^2.0.31
• Files: package.json
• Timeline: Phase 1 Week 1

CVE-2: Weak Password Hashing

• Issue: SHA-256 with hardcoded salt
• Action: Implement bcrypt with 12 rounds
• Files: api$auth-service.ts:580-588
• Timeline: Phase 1 Week 1

CVE-3: Hardcoded Default Credentials

• Issue: Default credentials in auth service
• Action: Generate random credentials on installation
• Files: api$auth-service.ts:602-643
• Timeline: Phase 1 Week 1

HIGH-1: Command Injection

• Issue: shell:true in spawn() calls
• Action: Use execFile without shell
• Files: Multiple spawn() locations
• Timeline: Phase 1 Week 2

HIGH-2: Path Traversal

• Issue: Unvalidated file paths
• Action: Implement path.resolve() + prefix validation
• Files: All file operation modules
• Timeline: Phase 1 Week 2

Security Boundaries

• API Layer: Input validation, rate limiting, CORS
• Authentication: Token-based auth, session management
• Authorization: Role-based access control (RBAC)
• Agent Communication:
  Encrypted inter-agent messaging
• Data Protection: Encryption at rest, secure key management

Secure Patterns Catalog

Input Validation

// Zod-based validation
const TaskInputSchema = z.object({
  taskId: z.string().uuid(),
  content: z.string().max(10000),
  agentType: z.enum(['security', 'core', 'integration'])
});

Path Sanitization

// Secure path handling
function securePath(userPath: string, allowedPrefix: string): string {
  const resolved = path.resolve(allowedPrefix, userPath);
  if (!resolved.startsWith(path.resolve(allowedPrefix))) {
    throw new SecurityError('Path traversal detected');
  }
  return resolved;
}

Command Execution

// Safe command execution
import { execFile } from 'child_process';

// ❌ Dangerous: shell injection possible
// exec(`git ${userInput}`, { shell: true });

// ✅ Safe: no shell interpretation
execFile('git', [userInput], { shell: false });
