检查 C++ 代码中的 const 正确性

参数:
    code: 要检查的 C++ 代码

返回:
    const 正确性检查报告，包括缺少 const 的地方和改进建议

Implementation Reference

• cpp_style/tools/const_checker.py:10-32 (handler)

  Core handler function that implements the logic for checking const correctness in C++ code. It orchestrates multiple specialized checks and generates a formatted report.

  def check_const_correctness(self, code: str) -> Tuple[List[Dict], str]:
      """
      检查代码中的 const 正确性
  
      Args:
          code: 要检查的 C++ 代码
  
      Returns:
          (问题列表, 格式化的检查报告)
      """
      issues = []
  
      # 检查各种 const 使用问题
      issues.extend(self._check_member_functions(code))
      issues.extend(self._check_parameters(code))
      issues.extend(self._check_return_values(code))
      issues.extend(self._check_variables(code))
      issues.extend(self._check_pointers_refs(code))
  
      # 生成报告
      report = self._generate_report(issues)
  
      return issues, report

• cpp_style_server.py:128-142 (registration)

  Registration of the MCP tool 'check_const_correctness' using the @mcp.tool() decorator. This wrapper function calls the core checker implementation.

  @mcp.tool()
  def check_const_correctness(code: str) -> str:
      """
      检查 C++ 代码中的 const 正确性
  
      参数:
          code: 要检查的 C++ 代码
  
      返回:
          const 正确性检查报告，包括缺少 const 的地方和改进建议
      """
      checker = get_const_checker()
      issues, report = checker.check_const_correctness(code)
      return report

• cpp_style/tools/const_checker.py:307-316 (helper)

  Singleton factory function that provides the global ConstCorrectnessChecker instance used by the tool.

  # 全局实例
  _checker = None
  
  def get_checker() -> ConstCorrectnessChecker:
      """获取全局 const 正确性检查器实例"""
      global _checker
      if _checker is None:
          _checker = ConstCorrectnessChecker()
      return _checker
