What it does

Security Review is an agent skill from xu-xiang/everything-claude-code-zh. 在添加身份验证、处理用户输入、操作机密信息、创建 API 接口或实现支付/敏感功能时使用此技能。提供全面的安全自查清单和模式。

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `cloud-infrastructure-security.md`).

It sits in Security, covering Security review, Web application vulnerabilities and Authentication. It works with Supabase and SQL. The repository describes itself as: everything-claude-code 中文翻译项目:完整的 Claude Code 配置集合(agents, skills, hooks, commands, rules, MCPs)。源自 Anthropic 黑客松获胜者的实战配置,助力中文工程师高效理解与使用 Claude Code。 The licence is MIT.

When your agent uses it

  • Tasks that involve Security review
  • Tasks that involve Web application vulnerabilities
  • Tasks that involve Authentication

Example prompts

  • “/security-review”

Requirements

  • Node.js
  • A credential in OPENAI_API_KEY

Workflow steps

10 steps, taken from the step headings in SKILL.md.

  1. 机密管理(Secrets Management)
  2. 输入验证(Input Validation)
  3. SQL 注入防护(SQL Injection Prevention)
  4. 身份验证与授权(Authentication & Authorization)
  5. XSS 防护(XSS Prevention)
  6. CSRF 防护(CSRF Protection)
  7. 速率限制(Rate Limiting)
  8. 敏感数据泄露(Sensitive Data Exposure)
  9. 区块链安全 (Solana)(Blockchain Security)
  10. 依赖项安全(Dependency Security)

What it can do on your machine

Read from SKILL.md and the folder at commit dfbf946. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • owasp.org
    • nextjs.org
    • supabase.com
    • portswigger.net

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Security Review loads about 2.4k tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:45
    - [ ] `.env.local` 已包含在 .gitignore 中

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ECC

安全审查技能(Security Review Skill)

此技能(Skill)旨在确保所有代码遵循安全最佳实践,并识别潜在的漏洞。

何时启用

  • 实现身份验证(Authentication)或授权(Authorization)时
  • 处理用户输入或文件上传时
  • 创建新的 API 接口(Endpoints)时
  • 操作机密(Secrets)或凭据(Credentials)时
  • 实现支付功能时
  • 存储或传输敏感数据时
  • 集成第三方 API 时

安全自查清单

1. 机密管理(Secrets Management)
❌ 严禁行为
typescript
const apiKey = "sk-proj-xxxxx"  // 硬编码机密
const dbPassword = "password123" // 出现在源代码中
✅ 推荐做法
typescript
const apiKey = process.env.OPENAI_API_KEY
const dbUrl = process.env.DATABASE_URL

// 验证机密是否存在
if (!apiKey) {
  throw new Error('未配置 OPENAI_API_KEY')
}
验证步骤
  • 无硬编码的 API 密钥、令牌(Tokens)或密码
  • 所有机密均存储在环境变量中
  • .env.local 已包含在 .gitignore 中
  • Git 历史记录中不包含机密信息
  • 生产环境机密配置在托管平台(如 Vercel, Railway)
2. 输入验证(Input Validation)
始终验证用户输入
typescript
import { z } from 'zod'

// 定义验证模式(Schema)
const CreateUserSchema = z.object({
  email: z.string().email(),
  name: z.string().min(1).max(100),
  age: z.number().int().min(0).max(150)
})

// 在处理前进行验证
export async function createUser(input: unknown) {
  try {
    const validated = CreateUserSchema.parse(input)
    return await db.users.create(validated)
  } catch (error) {
    if (error instanceof z.ZodError) {
      return { success: false, errors: error.errors }
    }
    throw error
  }
}
文件上传验证
typescript
function validateFileUpload(file: File) {
  // 大小检查(最大 5MB)
  const maxSize = 5 * 1024 * 1024
  if (file.size > maxSize) {
    throw new Error('文件过大(最大 5MB)')
  }

  // 类型检查
  const allowedTypes = ['image/jpeg', 'image/png', 'image/gif']
  if (!allowedTypes.includes(file.type)) {
    throw new Error('无效的文件类型')
  }

  // 扩展名检查
  const allowedExtensions = ['.jpg', '.jpeg', '.png', '.gif']
  const extension = file.name.toLowerCase().match(/\.[^.]+$/)?.[0]
  if (!extension || !allowedExtensions.includes(extension)) {
    throw new Error('无效的文件扩展名')
  }

  return true
}
验证步骤
  • 所有用户输入均通过模式(Schemas)验证
  • 文件上传受到限制(大小、类型、扩展名)
  • 查询中不直接使用用户输入
  • 使用白名单验证(而非黑名单)
  • 错误消息不泄露敏感信息
3. SQL 注入防护(SQL Injection Prevention)
❌ 严禁拼接 SQL
typescript
// 危险 - 存在 SQL 注入漏洞
const query = `SELECT * FROM users WHERE email = '${userEmail}'`
await db.query(query)
✅ 始终使用参数化查询
typescript
// 安全 - 参数化查询
const { data } = await supabase
  .from('users')
  .select('*')
  .eq('email', userEmail)

// 或使用原始 SQL
await db.query(
  'SELECT * FROM users WHERE email = $1',
  [userEmail]
)
验证步骤
  • 所有数据库查询均使用参数化查询
  • SQL 中无字符串拼接
  • 正确使用 ORM 或查询构建器(Query Builder)
  • Supabase 查询已正确过滤
4. 身份验证与授权(Authentication & Authorization)
JWT 令牌处理
typescript
// ❌ 错误做法:存储在 localStorage 中(易受 XSS 攻击)
localStorage.setItem('token', token)

// ✅ 正确做法:使用 httpOnly cookies
res.setHeader('Set-Cookie',
  `token=${token}; HttpOnly; Secure; SameSite=Strict; Max-Age=3600`)
授权检查
typescript
export async function deleteUser(userId: string, requesterId: string) {
  // 务必先验证授权
  const requester = await db.users.findUnique({
    where: { id: requesterId }
  })

  if (requester.role !== 'admin') {
    return NextResponse.json(
      { error: 'Unauthorized' },
      { status: 403 }
    )
  }

  // 执行删除操作
  await db.users.delete({ where: { id: userId } })
}
行级安全性(Supabase Row Level Security)
sql
-- 在所有表上启用 RLS
ALTER TABLE users ENABLE ROW LEVEL SECURITY;

-- 用户只能查看自己的数据
CREATE POLICY "Users view own data"
  ON users FOR SELECT
  USING (auth.uid() = id);

-- 用户只能更新自己的数据
CREATE POLICY "Users update own data"
  ON users FOR UPDATE
  USING (auth.uid() = id);
验证步骤
  • 令牌存储在 httpOnly cookies 中(而非 localStorage)
  • 敏感操作前进行授权检查
  • 在 Supabase 中启用了行级安全性(RLS)
  • 实现了基于角色的访问控制(RBAC)
  • 会话管理(Session Management)安全
5. XSS 防护(XSS Prevention)
清理 HTML
typescript
import DOMPurify from 'isomorphic-dompurify'

// 始终清理用户提供的 HTML
function renderUserContent(html: string) {
  const clean = DOMPurify.sanitize(html, {
    ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'p'],
    ALLOWED_ATTR: []
  })
  return <div dangerouslySetInnerHTML={{ __html: clean }} />
}
内容安全策略(Content Security Policy)
typescript
// next.config.js
const securityHeaders = [
  {
    key: 'Content-Security-Policy',
    value: `
      default-src 'self';
      script-src 'self' 'unsafe-eval' 'unsafe-inline';
      style-src 'self' 'unsafe-inline';
      img-src 'self' data: https:;
      font-src 'self';
      connect-src 'self' https://api.example.com;
    `.replace(/\s{2,}/g, ' ').trim()
  }
]
验证步骤
  • 清理了用户提供的 HTML
  • 配置了 CSP 响应头
  • 无未经验证的动态内容渲染
  • 使用了 React 内置的 XSS 防护机制
6. CSRF 防护(CSRF Protection)
CSRF 令牌(Tokens)
typescript
import { csrf } from '@/lib/csrf'

export async function POST(request: Request) {
  const token = request.headers.get('X-CSRF-Token')

  if (!csrf.verify(token)) {
    return NextResponse.json(
      { error: 'Invalid CSRF token' },
      { status: 403 }
    )
  }

  // 处理请求
}
SameSite Cookies
typescript
res.setHeader('Set-Cookie',
  `session=${sessionId}; HttpOnly; Secure; SameSite=Strict`)
验证步骤
  • 在状态变更操作中使用 CSRF 令牌
  • 所有 Cookie 均设置 SameSite=Strict
  • 实现了双重提交 Cookie 模式(Double-submit cookie pattern)
7. 速率限制(Rate Limiting)
API 速率限制
typescript
import rateLimit from 'express-rate-limit'

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 分钟
  max: 100, // 每个窗口期最大 100 次请求
  message: '请求过于频繁'
})

// 应用于路由
app.use('/api/', limiter)
高消耗操作
typescript
// 为搜索操作设置更严格的速率限制
const searchLimiter = rateLimit({
  windowMs: 60 * 1000, // 1 分钟
  max: 10, // 每分钟最大 10 次请求
  message: '搜索请求过于频繁'
})

app.use('/api/search', searchLimiter)
验证步骤
  • 所有 API 接口均设置了速率限制
  • 对高消耗操作设置了更严格的限制
  • 基于 IP 的速率限制
  • 基于用户的速率限制(已认证用户)
8. 敏感数据泄露(Sensitive Data Exposure)
日志记录
typescript
// ❌ 错误做法:记录敏感数据
console.log('User login:', { email, password })
console.log('Payment:', { cardNumber, cvv })

// ✅ 正确做法:屏蔽敏感数据
console.log('User login:', { email, userId })
console.log('Payment:', { last4: card.last4, userId })
错误消息
typescript
// ❌ 错误做法:泄露内部细节
catch (error) {
  return NextResponse.json(
    { error: error.message, stack: error.stack },
    { status: 500 }
  )
}

// ✅ 正确做法:通用的错误消息
catch (error) {
  console.error('Internal error:', error)
  return NextResponse.json(
    { error: '发生错误,请稍后重试。' },
    { status: 500 }
  )
}
验证步骤
  • 日志中不包含密码、令牌或机密
  • 向用户展示通用的错误消息
  • 详细错误仅记录在服务器日志中
  • 不向用户暴露堆栈轨迹(Stack traces)
9. 区块链安全 (Solana)(Blockchain Security)
钱包验证
typescript
import { verify } from '@solana/web3.js'

async function verifyWalletOwnership(
  publicKey: string,
  signature: string,
  message: string
) {
  try {
    const isValid = verify(
      Buffer.from(message),
      Buffer.from(signature, 'base64'),
      Buffer.from(publicKey, 'base64')
    )
    return isValid
  } catch (error) {
    return false
  }
}
交易验证
typescript
async function verifyTransaction(transaction: Transaction) {
  // 验证收款人
  if (transaction.to !== expectedRecipient) {
    throw new Error('无效的收款人')
  }

  // 验证金额
  if (transaction.amount > maxAmount) {
    throw new Error('金额超出限制')
  }

  // 验证用户余额充足
  const balance = await getBalance(transaction.from)
  if (balance < transaction.amount) {
    throw new Error('余额不足')
  }

  return true
}
验证步骤
  • 已验证钱包签名
  • 已校验交易详情
  • 交易前进行余额检查
  • 不存在盲签(Blind transaction signing)行为
10. 依赖项安全(Dependency Security)
定期更新
bash
# 检查漏洞
npm audit

# 自动修复可修复的问题
npm audit fix

# 更新依赖
npm update

# 检查过期的包
npm outdated
锁定文件
bash
# 务必提交锁定文件
git add package-lock.json

# 在 CI/CD 中使用以确保可重现的构建
npm ci  # 而不是 npm install
验证步骤
  • 依赖项保持最新
  • 无已知漏洞(npm audit clean)
  • 已提交锁定文件
  • 在 GitHub 上启用了 Dependabot
  • 定期进行安全更新

安全测试(Security Testing)

自动化安全测试
typescript
// 测试身份验证
test('需要身份验证', async () => {
  const response = await fetch('/api/protected')
  expect(response.status).toBe(401)
})

// 测试授权
test('需要管理员角色', async () => {
  const response = await fetch('/api/admin', {
    headers: { Authorization: `Bearer ${userToken}` }
  })
  expect(response.status).toBe(403)
})

// 测试输入验证
test('拒绝无效输入', async () => {
  const response = await fetch('/api/users', {
    method: 'POST',
    body: JSON.stringify({ email: 'not-an-email' })
  })
  expect(response.status).toBe(400)
})

// 测试速率限制
test('执行速率限制', async () => {
  const requests = Array(101).fill(null).map(() =>
    fetch('/api/endpoint')
  )

  const responses = await Promise.all(requests)
  const tooManyRequests = responses.filter(r => r.status === 429)

  expect(tooManyRequests.length).toBeGreaterThan(0)
})
