 # CLAUDE.md  
   
 Authentication  
 - Use JWT tokens, not sessions  
 - Store in httpOnly cookies  
   
 Testing  
 - Write tests for all API endpoints  
 - Use Jest, not Mocha  
   
 Error Handling  
 - Return structured errors: { error: string, code: number }

 /compact  
   
 # 定向压缩（保留特定上下文）  
 /compact retain the error handling patterns and auth module changes

 claude  
 Shift+Tab  # Enable plan mode  
   
 # 2. 描述重构  
 "Refactor auth module to use bcrypt instead of plain passwords"  
   
 # 3. 在执行前审查计划  
 # Approve or adjust  
 # 4. 监控上下文  
 /context
