Claude Code Best Practices Guide: Secret Weapons for Efficient Development

🎯 Introduction

Mastering the correct usage of Claude Code is key to improving development efficiency. This guide shares proven best practices to help you maximize Claude Code's potential.

📋 Project Configuration Optimization

1. Create CLAUDE.md Documentation

Create a CLAUDE.md file in your project root - this is key for Claude Code to understand your project:

# CLAUDE.md

## Project Overview
- Tech Stack: React + TypeScript + Node.js
- Architecture Pattern: Microservices Architecture
- Database: PostgreSQL + Redis

## Core Commands
- `npm run dev` - Development environment
- `npm run test` - Run tests
- `npm run build` - Production build
- `npm run lint` - Code linting

## Project Structure
- `src/components/` - React components
- `src/services/` - API service layer
- `src/utils/` - Utility functions
- `tests/` - Test files

2. Configure Development Preferences

Clearly specify your preferences in global configuration:

## Development Preferences
- Package Manager: pnpm (mandatory)
- Code Style: ESLint + Prettier
- Testing Framework: Jest + React Testing Library
- CSS Solution: Tailwind CSS

💡 Efficient Interaction Techniques

1. Precise Requirement Description

Good Example:

"Add avatar upload functionality to UserProfile component, supporting drag-and-drop and click upload, file size limit 5MB for JPG/PNG formats, show preview after upload"

Avoid Vague Descriptions:

"Add upload feature to user page"

2. Provide Sufficient Context

• Share relevant code file paths
• Explain current tech stack and constraints
• Describe expected behavior and results
• Mention relevant business logic

3. Handle Complex Tasks Step by Step

For complex features, break them down into multiple steps:

1. First design data models and API interfaces
2. Implement backend API logic
3. Create frontend components and state management
4. Write test cases
5. Optimize performance and user experience

🔧 Code Quality Management

1. Leverage Automated Code Review

• Have Claude Code review code changes before each commit
• Focus on code standards, performance optimization, and security issues
• Ensure test coverage meets project standards

2. Continuous Refactoring Strategy

# Regular code health checks
claude-code analyze --scope=project --focus=technical-debt
claude-code refactor --target=performance --safe-mode

3. Test-Driven Development

• First have Claude Code help write test cases
• Implement feature code based on test cases
• Ensure tests cover key business logic

🚀 Efficiency Enhancement Tips

1. Fully Utilize Sub-Agent System

Choose appropriate specialized agents based on task type:

• Frontend Tasks: Use frontend-developer agent

  /agent frontend-developer "Optimize React component performance, reduce unnecessary re-renders"

• Backend Architecture: Use backend-architect agent

  /agent backend-architect "Design user authentication system API architecture"

• DevOps Tasks: Use devops-automator agent

  /agent devops-automator "Set up GitHub Actions automated deployment workflow"

2. MCP Service Integration

Configure and use MCP (Model Context Protocol) services:

{
  "mcp": {
    "servers": {
      "memory": {
        "command": "npx @knowall-ai/mcp-neo4j-agent-memory",
        "transport": "stdio"
      },
      "browser-tools": {
        "command": "npx @agentdeskai/browser-tools-mcp",
        "transport": "stdio"
      }
    }
  }
}

3. Intelligent Code Generation Workflow

a) Component Development Workflow

1. Describe component requirements and design specifications
2. Generate basic component structure
3. Add styling and interaction logic
4. Write test cases
5. Optimize performance and accessibility

b) API Development Workflow

1. Design API interface specifications
2. Generate route and controller code
3. Implement data validation and business logic
4. Write API tests
5. Add error handling and logging

🛡️ Security and Compliance

1. Code Security Checks

• Regular security scans
• Check dependency vulnerabilities
• Verify input validation and SQL injection protection
• Ensure sensitive information is not committed to codebase

2. Compliance Management

## Compliance Checklist
- [ ] GDPR data privacy compliance
- [ ] Open source license compatibility
- [ ] Enterprise security policy adherence
- [ ] Code review process completeness

📊 Performance Monitoring and Optimization

1. Code Performance Analysis

• Use Claude Code to analyze performance bottlenecks
• Identify memory leaks and unnecessary computations
• Optimize database queries and API calls
• Implement caching strategies

2. Build Optimization

# Analyze bundle size
claude-code analyze --type=bundle-size --suggestions

# Optimize webpack configuration
claude-code optimize --target=build-performance

🔄 Team Collaboration Best Practices

1. Unified Development Standards

• Establish team-level Claude Code configuration
• Share project templates and code standards
• Unify third-party library and tool choices

2. Knowledge Sharing

• Document Claude Code usage tips and experiences
• Share effective prompts and workflows
• Build project-specific best practice documentation

3. Code Review Integration

# .github/workflows/claude-review.yml
name: Claude Code Review
on: [pull_request]
jobs:
  review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Claude Code Review
        uses: anthropic/claude-code-action@v1
        with:
          focus: security,performance,maintainability

🎯 Common Pitfalls and How to Avoid Them

1. Over-reliance on AI

• Maintain understanding and control of code
• Verify AI-generated code logic
• Regular manual code reviews

2. Ignoring Tests

• Always write tests for AI-generated code
• Verify edge cases and exception handling
• Ensure test coverage of core business logic

3. Improper Configuration

• Regularly update Claude Code configuration
• Adjust settings according to project changes
• Monitor AI suggestion quality and relevance

🌟 Advanced Techniques

1. Custom Tool Creation

# Create project-specific tools
class DatabaseMigrationTool:
    def analyze_schema_changes(self):
        # Analyze database schema changes
        pass
    
    def generate_migration_script(self):
        # Generate migration script
        pass

2. Workflow Automation

# Create custom command aliases
alias code-review="claude-code review --strict-mode --focus=all"
alias quick-fix="claude-code fix --auto-commit --run-tests"
alias optimize="claude-code optimize --performance --maintainability"
