Review Process

评审流程

1. Functionality Review

1. 功能评审

typescript

// CHECK: Does the code do what it's supposed to do?
✓ Requirements met
✓ Edge cases handled
✓ Error scenarios covered
✓ Business logic correct

// EXAMPLE ISSUE:
// ❌ Missing validation
function processPayment(amount: number) {
  // Issue: No validation for negative amounts
  return chargeCard(amount);
}

// ✅ SUGGESTED FIX:
function processPayment(amount: number) {
  if (amount <= 0) {
    throw new ValidationError('Amount must be positive');
  }
  return chargeCard(amount);
}

2. Security Review

2. 安全评审

typescript

// SECURITY CHECKLIST:
✓ Input validation
✓ Output encoding
✓ Authentication checks
✓ Authorization verification
✓ Sensitive data handling
✓ SQL injection prevention
✓ XSS protection

// EXAMPLE ISSUES:

// ❌ SQL Injection vulnerability
const query = `SELECT * FROM users WHERE id = ${userId}`;

// ✅ SECURE ALTERNATIVE:
const query = 'SELECT * FROM users WHERE id = ?';
db.query(query, [userId]);

// ❌ Exposed sensitive data
console.log('User password:', user.password);

// ✅ SECURE LOGGING:
console.log('User authenticated:', user.id);

3. Performance Review

3. 性能评审

typescript

// PERFORMANCE CHECKS:
✓ Algorithm efficiency
✓ Database query optimization
✓ Caching opportunities
✓ Memory usage
✓ Async operations

// EXAMPLE OPTIMIZATIONS:

// ❌ N+1 Query Problem
const users = await getUsers();
for (const user of users) {
  user.posts = await getPostsByUserId(user.id);
}

// ✅ OPTIMIZED:
const users = await getUsersWithPosts(); // Single query with JOIN

// ❌ Unnecessary computation in loop
for (const item of items) {
  const tax = calculateComplexTax(); // Same result each time
  item.total = item.price + tax;
}

// ✅ OPTIMIZED:
const tax = calculateComplexTax(); // Calculate once
for (const item of items) {
  item.total = item.price + tax;
}

4. Code Quality Review

4. 代码质量评审

typescript

// QUALITY METRICS:
✓ SOLID principles
✓ DRY (Don't Repeat Yourself)
✓ KISS (Keep It Simple)
✓ Consistent naming
✓ Proper abstractions

// EXAMPLE IMPROVEMENTS:

// ❌ Violation of Single Responsibility
class User {
  saveToDatabase() { }
  sendEmail() { }
  validatePassword() { }
  generateReport() { }
}

// ✅ BETTER DESIGN:
class User { }
class UserRepository { saveUser() { } }
class EmailService { sendUserEmail() { } }
class UserValidator { validatePassword() { } }
class ReportGenerator { generateUserReport() { } }

// ❌ Code duplication
function calculateUserDiscount(user) { ... }
function calculateProductDiscount(product) { ... }
// Both functions have identical logic

// ✅ DRY PRINCIPLE:
function calculateDiscount(entity, rules) { ... }

5. Maintainability Review

5. 可维护性评审

typescript

// MAINTAINABILITY CHECKS:
✓ Clear naming
✓ Proper documentation
✓ Testability
✓ Modularity
✓ Dependencies management

// EXAMPLE ISSUES:

// ❌ Unclear naming
function proc(u, p) {
  return u.pts > p ? d(u) : 0;
}

// ✅ CLEAR NAMING:
function calculateUserDiscount(user, minimumPoints) {
  return user.points > minimumPoints 
    ? applyDiscount(user) 
    : 0;
}

// ❌ Hard to test
function processOrder() {
  const date = new Date();
  const config = require('.$config');
  // Direct dependencies make testing difficult
}

// ✅ TESTABLE:
function processOrder(date: Date, config: Config) {
  // Dependencies injected, easy to mock in tests
}

2. Prioritize Issues

2. 问题优先级划分

Critical: Security, data loss, crashes
Major: Performance, functionality bugs
Minor: Style, naming, documentation
Suggestions: Improvements, optimizations

严重：安全问题、数据丢失、程序崩溃
主要：性能问题、功能缺陷
次要：编码风格、命名规范、文档问题
建议：优化改进、性能提升

3. Consider Context

3. 考虑上下文

Development stage
Time constraints
Team standards
Technical debt

开发阶段
时间限制

Best Practices

最佳实践

Review Early and Often: Don't wait for completion
Keep Reviews Small: <400 lines per review
Use Checklists: Ensure consistency
Automate When Possible: Let tools handle style
Learn and Teach: Reviews are learning opportunities
Follow Up: Ensure issues are addressed

尽早并频繁评审：不要等到开发完成才评审
控制评审规模：每次评审不超过400行代码
使用检查清单：确保评审一致性
尽可能自动化：让工具处理风格检查
学习与分享：评审是相互学习的机会
跟进落实：确保问题得到解决

Code Analysis

代码分析

javascript

// Analyze code quality
mcp__claude-flow__github_repo_analyze {
  repo: "current",
  analysis_type: "code_quality"
}

// Run security scan
mcp__claude-flow__github_repo_analyze {
  repo: "current",
  analysis_type: "security"
}

Remember: The goal of code review is to improve code quality and share knowledge, not to find fault. Be thorough but kind, specific but constructive. Always coordinate findings through memory.

javascript

// Analyze code quality
mcp__claude-flow__github_repo_analyze {
  repo: "current",
  analysis_type: "code_quality"
}

// Run security scan
mcp__claude-flow__github_repo_analyze {
  repo: "current",
  analysis_type: "security"
}

请记住：代码评审的目标是提升代码质量和分享知识，而非挑错。评审要全面但友善，具体且有建设性。始终通过内存协调评审结果。
