• src/server.ts:632-681 (handler)

  The handler for the 'cost_estimate' tool. It takes a task description, estimates token input/output based on task length and complexity keywords, calculates approximate costs using GPT-4o pricing, estimates execution time using average stats, and returns a formatted Markdown report with the estimates.

          case 'cost_estimate': {
            const { task } = args as { task: string };
            
            // 简单的 token 估算（基于任务描述长度和复杂度）
            const taskTokens = Math.ceil(task.length / 4); // 粗略估算输入 tokens
            const isComplex = task.includes('优化') || task.includes('架构') || task.includes('重构') || task.includes('安全');
            const estimatedExperts = isComplex ? 3 : 2;
            const tokensPerExpert = isComplex ? 4000 : 2000;
            
            const estimatedInputTokens = taskTokens + (estimatedExperts * 500); // 系统提示词
            const estimatedOutputTokens = estimatedExperts * tokensPerExpert;
            const totalTokens = estimatedInputTokens + estimatedOutputTokens;
            
            // 费用估算（基于 GPT-4o 价格：$5/1M input, $15/1M output）
            const inputCost = (estimatedInputTokens / 1000000) * 5;
            const outputCost = (estimatedOutputTokens / 1000000) * 15;
            const totalCost = inputCost + outputCost;
            
            // 耗时估算
            const avgDuration = globalStats.getGlobalStats().avgDuration || 5000;
            const estimatedTime = (avgDuration * estimatedExperts) / 1000;
            
            const estimate = `# 💰 成本预估
  
  ## 任务分析
  - **任务描述**: ${task.slice(0, 100)}${task.length > 100 ? '...' : ''}
  - **复杂度**: ${isComplex ? '高' : '中'}
  - **预计专家数**: ${estimatedExperts} 个
  
  ## Token 预估
  | 类型 | 数量 |
  |------|------|
  | 输入 Tokens | ~${estimatedInputTokens.toLocaleString()} |
  | 输出 Tokens | ~${estimatedOutputTokens.toLocaleString()} |
  | **总计** | **~${totalTokens.toLocaleString()}** |
  
  ## 费用预估 (基于 GPT-4o)
  - 输入: $${inputCost.toFixed(4)}
  - 输出: $${outputCost.toFixed(4)}
  - **总计**: **$${totalCost.toFixed(4)}**
  
  ## 时间预估
  - 预计耗时: ~${estimatedTime.toFixed(0)} 秒
  
  > ⚠️ 这是粗略估算，实际费用取决于模型选择和任务复杂度`;
  
            return {
              content: [{ type: 'text', text: estimate }],
            };
          }

• src/server.ts:275-288 (registration)

  The tool registration entry in the listTools handler, defining the name, description, and input schema (requiring a 'task' string).

  {
    name: 'cost_estimate',
    description: '预估任务执行成本（Token 用量、预计耗时）',
    inputSchema: {
      type: 'object',
      properties: {
        task: {
          type: 'string',
          description: '要预估的任务描述',
        },
      },
      required: ['task'],
    },
  },

• src/server.ts:278-287 (schema)

  The input schema definition for the 'cost_estimate' tool, specifying an object with a required 'task' string property.

  inputSchema: {
    type: 'object',
    properties: {
      task: {
        type: 'string',
        description: '要预估的任务描述',
      },
    },
    required: ['task'],
  },
