SequentialThinking 技术调研报告

03 Apr 2025

一、项目概览

  • Break down complex problems into manageable steps

  • Revise and refine thoughts as understanding deepens
  • Branch into alternative paths of reasoning
  • Adjust the total number of thoughts dynamically
  • Generate and verify solution hypotheses

二、核心架构

主类功能

  • 思维历史管理: True
  • 分支系统: True
  • 输入验证: True

数据接口

interface ThoughtData {
thought: string;
  thoughtNumber: number;
  totalThoughts: number;
  isRevision?: boolean;
  revisesThought?: number;
  branchFromThought?: number;
  branchId?: string;
  needsMoreThoughts?: boolean;
  nextThoughtNeeded: boolean;
}

三、依赖分析

{
  "@modelcontextprotocol/sdk": "0.5.0",
  "chalk": "^5.3.0",
  "yargs": "^17.7.2"
}

五、实际应用场景

1. 技术方案设计

{
  "thought": "评估微服务通信协议",
  "thoughtNumber": 1,
  "totalThoughts": 3,
  "nextThoughtNeeded": true
}

➔ 后续思考自动编号为2，保留协议选型上下文

2. 故障诊断流程

{
  "thought": "API响应慢的可能原因",
  "thoughtNumber": 2,
  "isRevision": true,
  "revisesThought": 1,
  "branchFromThought": 1,
  "branchId": "network-issues"
}

➔ 创建诊断分支，独立探索网络问题可能性

3. 团队协作场景

[
  {
    "thought": "前端缓存方案设计",
    "thoughtNumber": 1,
    "branchId": "frontend-team"
  },
  {
    "thought": "后端API优化",
    "thoughtNumber": 1, 
    "branchId": "backend-team"
  }
]

➔ 不同团队共享基础问题上下文，独立开展分支思考

六、源码实现细节

1. 输入验证机制

// 方法实现未找到

验证逻辑：

  • 类型安全检查（TypeScript接口）
  • 必要字段校验（thoughtNumber等）
  • 分支ID格式验证

2. 思维处理流程

// 方法实现未找到

关键步骤：

  1. 历史记录更新
  2. 分支上下文维护
  3. 下一步标记设置

3. 分支创建实现

// 方法实现未找到

分支特性：

  • 基于父思维创建副本
  • 独立版本管理
  • 分支隔离存储

四、部署信息

Docker:

docker build -t mcp/sequentialthinking -f src/sequentialthinking/Dockerfile .
