  1. Review AGENTS.md for a complete compilation of all rules with examples
  2. Reference specific rules from
    rules/
    directory for deep dives
  3. Follow priority order: Security → Performance → Correctness → Maintainability
  1. 查看AGENTS.md 获取包含示例的完整规则汇编
  2. 参考
    rules/
    目录中的特定规则
    进行深入审查
  3. 遵循优先级顺序:安全性 → 性能 → 正确性 → 可维护性

Available Rules

可用规则

Security (CRITICAL)
  • SQL Injection Prevention
  • XSS Prevention
Performance (HIGH)
  • Avoid N+1 Query Problem
Correctness (HIGH)
  • Proper Error Handling
Maintainability (MEDIUM)
  • Use Meaningful Variable Names
  • Add Type Hints
安全性(CRITICAL)
  • SQL Injection Prevention
  • XSS Prevention
性能(HIGH)

Review Process

审查流程

1. Security First (CRITICAL)

1. 安全优先(CRITICAL)

Look for vulnerabilities that could lead to data breaches or unauthorized access:
  • SQL injection
  • XSS (Cross-Site Scripting)
  • Authentication/authorization bypasses
  • Hardcoded secrets
  • Insecure dependencies
寻找可能导致数据泄露或未授权访问的漏洞:
  • SQL injection
  • XSS (Cross-Site Scripting)
  • 身份验证/授权绕过
  • 硬编码密钥
  • 不安全的依赖项

2. Performance (HIGH)

2. 性能(HIGH)

Identify code that will cause slow performance at scale:
  • N+1 database queries
  • Missing indexes
  • Inefficient algorithms
  • Memory leaks
  • Unnecessary API calls
识别在大规模场景下会导致性能变慢的代码:
  • N+1数据库查询
  • 缺失索引
  • 低效算法
  • 内存泄漏
  • 不必要的API调用

3. Correctness (HIGH)

3. 正确性(HIGH)

Find bugs and edge cases:
  • Error handling gaps
  • Race conditions
  • Off-by-one errors
  • Null/undefined handling
  • Input validation
查找错误和边缘情况:
  • 错误处理漏洞
  • 竞态条件
  • 差一错误
  • Null/未定义值处理
  • 输入验证

4. Maintainability (MEDIUM)

4. 可维护性(MEDIUM)

Improve code quality for long-term health:
  • Clear naming
  • Type safety
  • DRY principle
  • Single responsibility
  • Documentation
提升代码的长期健康性:
  • 清晰的命名
  • 类型安全
  • DRY原则
  • 单一职责
  • 文档

5. Testing

5. 测试

Verify adequate coverage:
  • Unit tests for new code
  • Edge case testing
  • Error path testing
  • Integration tests where needed
验证足够的测试覆盖率:
  • 新代码的单元测试
  • 边缘场景测试
  • 错误路径测试
  • 必要时的集成测试

Review Output Format

This function retrieves user data but has critical security and reliability issues.
将你的审查结果按以下结构组织:
markdown
此函数用于检索用户数据,但存在严重的安全和可靠性问题。

Critical Issues 🔴

严重问题 🔴

  1. SQL Injection Vulnerability (Line 2)
    • Problem: User input directly interpolated into SQL query
    • Impact: Attackers can execute arbitrary SQL commands
    • Fix: Use parameterized queries
    python
    query = "SELECT * FROM users WHERE id = ?"
    result = db.execute(query, (user_id,))
  1. SQL Injection Vulnerability(第2行)
    • 问题: 用户输入直接插入到SQL查询中
    • 影响: 攻击者可以执行任意SQL命令
    • 修复方案: 使用参数化查询
    python
    query = "SELECT * FROM users WHERE id = ?"
    result = db.execute(query, (user_id,))

High Priority 🟠

高优先级 🟠

  1. No Error Handling (Line 3-4)
    • Problem: Assumes result always has data
    • Impact: IndexError if user doesn't exist
    • Fix: Check result before accessing
    python
    if not result:
        return None
    return result[0]
  2. Missing Type Hints (Line 1)
    • Problem: No type annotations
    • Impact: Reduces code clarity and IDE support
    • Fix: Add type hints
    python
    def get_user(user_id: int) -> Optional[Dict[str, Any]]:
  1. 无错误处理(第3-4行)
    • 问题: 假设查询结果始终包含数据
    • 影响: 如果用户不存在会触发IndexError
    • 修复方案: 在访问结果前进行检查
    python
    if not result:
        return None
    return result[0]
  2. 缺失Type Hints(第1行)
    • 问题: 没有类型注解
    • 影响: 降低代码清晰度和IDE支持
    • 修复方案: 添加类型提示
    python
    def get_user(user_id: int) -> Optional[Dict[str, Any]]:

Recommendations

建议

  • Add logging for debugging
  • Consider using an ORM to prevent SQL injection
  • Add input validation for user_id
  • 添加日志用于调试
  • 考虑使用ORM来防止SQL注入
  • 为user_id添加输入验证
