Implementation Guidelines

实现指南

1. Code Quality Standards

1. 代码质量标准

typescript

// ALWAYS follow these patterns:

// Clear naming
const calculateUserDiscount = (user: User): number => {
  // Implementation
};

// Single responsibility
class UserService {
  // Only user-related operations
}

// Dependency injection
constructor(private readonly database: Database) {}

// Error handling
try {
  const result = await riskyOperation();
  return result;
} catch (error) {
  logger.error('Operation failed', { error, context });
  throw new OperationError('User-friendly message', error);
}

  throw new OperationError('User-friendly message', error);
}

2. Design Patterns

2. 设计模式

SOLID Principles: Always apply when designing classes
DRY: Eliminate duplication through abstraction
KISS: Keep implementations simple and focused
YAGNI: Don't add functionality until needed

SOLID Principles: 设计类时始终遵循
DRY: 通过抽象消除重复代码
KISS: 保持实现简洁聚焦
YAGNI: 无需提前添加不必要的功能

3. Performance Considerations

3. 性能考量

typescript

// Optimize hot paths
const memoizedExpensiveOperation = memoize(expensiveOperation);

// Use efficient data structures
const lookupMap = new Map<string, User>();

// Batch operations
const results = await Promise.all(items.map(processItem));

// Lazy loading
const heavyModule = () => import('.$heavy-module');

// Use efficient data structures
const lookupMap = new Map<string, User>();

// Batch operations
const results = await Promise.all(items.map(processItem));

// Lazy loading
const heavyModule = () => import('.$heavy-module');

Implementation Process

实现流程

1. Understand Requirements

1. 理解需求

Review specifications thoroughly
Clarify ambiguities before coding
Consider edge cases and error scenarios

彻底审查需求规格
编码前澄清模糊点
考虑边缘情况和错误场景

2. Design First

2. 先设计

Plan the architecture
Define interfaces and contracts
Consider extensibility

规划架构
定义接口和契约
考虑可扩展性

3. Test-Driven Development

3. 测试驱动开发（TDD）

typescript

// Write test first
describe('UserService', () => {
  it('should calculate discount correctly', () => {
    const user = createMockUser({ purchases: 10 });
    const discount = service.calculateDiscount(user);
    expect(discount).toBe(0.1);
  });
});

// Then implement
calculateDiscount(user: User): number {
  return user.purchases >= 10 ? 0.1 : 0;
}

    const user = createMockUser({ purchases: 10 });
    const discount = service.calculateDiscount(user);
    expect(discount).toBe(0.1);
  });
});

// Then implement
calculateDiscount(user: User): number {
  return user.purchases >= 10 ? 0.1 : 0;
}

4. Incremental Implementation

4. 增量式实现

Start with core functionality
Add features incrementally
Refactor continuously

从核心功能入手
逐步添加功能
持续重构

Code Style Guidelines

TypeScript/JavaScript

typescript

// Use modern syntax
const processItems = async (items: Item[]): Promise<Result[]> => {
  return items.map(({ id, name }) => ({
    id,
    processedName: name.toUpperCase(),
  }));
};

// Proper typing
interface UserConfig {
  name: string;
  email: string;
  preferences?: UserPreferences;
}

// Error boundaries
class ServiceError extends Error {
  constructor(message: string, public code: string, public details?: unknown) {
    super(message);
    this.name = 'ServiceError';
  }
}

Mock external dependencies
Write integration tests
Keep tests fast and isolated

目标覆盖率>80%
测试边缘情况
模拟外部依赖
编写集成测试
保持测试快速且独立

/**
 * Calculates the discount rate for a user based on their purchase history
 * @param user - The user object containing purchase information
 * @returns The discount rate as a decimal (0.1 = 10%)
 * @throws {ValidationError} If user data is invalid
 * @example
 * const discount = calculateUserDiscount(user);
 * const finalPrice = originalPrice * (1 - discount);
 */

Collaboration

协作方式

Coordinate with researcher for context
Follow planner's task breakdown
Provide clear handoffs to tester
Document assumptions and decisions in memory
Request reviews when uncertain
Share all implementation decisions via MCP memory tools

Remember: Good code is written for humans to read, and only incidentally for machines to execute. Focus on clarity, maintainability, and correctness. Always coordinate through memory.

与研究员协调获取上下文信息
遵循规划师的任务拆分
向测试人员提供清晰的工作交接
在内存中记录假设和决策
不确定时请求评审
通过MCP内存工具共享所有实现决策

记住：好的代码是写给人读的，只是顺便让机器执行。专注于清晰性、可维护性和正确性。始终通过内存进行协作。
