代码库探索

本技能提供代码库探索的通用方法论,包含两种策略模式。

子文件

策略选择

场景 推荐策略 原因
快速了解某个模块 isolated-research 一次性探索,不污染上下文
理解复杂的跨模块流程 iterative-retrieval 需要多轮精炼
简单的文件/函数定位 直接 Grep/Glob 无需完整探索流程
新项目初始理解 iterative-retrieval 需要建立全局认知
调试特定 Bug isolated-research 聚焦单一问题
架构分析和文档化 iterative-retrieval 需要完整依赖图

通用探索方法

搜索工具选择

目标 工具 示例
按文件名/路径查找 Glob **/auth/**/*.ts
按代码内容查找 Grep "function authenticate"
读取完整文件 Read 直接读取已知路径文件
深度子任务(隔离) Task 派发子代理执行

搜索策略模式

## 入口点搜索

- 路由/API 端点
- 中间件
- main/index 文件
- 配置文件

## 定义搜索

- class/function 定义
- type/interface 定义
- 常量/枚举定义

## 使用搜索

- import/require 语句
- 函数调用点
- 类实例化

## 依赖搜索

- package.json
- import 图谱
- 模块边界

输出格式(通用)

所有探索结果应遵循统一格式:

## 探索报告

### 问题/目标

[描述探索的目标]

### 关键发现

| 文件                | 行号 | 功能说明       |
| ------------------- | ---- | -------------- |
| `src/auth/login.ts` | 42   | 登录验证入口   |
| `src/lib/jwt.ts`    | 15   | Token 生成逻辑 |

### 依赖关系

[可选:模块依赖图、调用链]

### 结论

[对问题的回答]

### 后续建议

[可选:建议的下一步动作]

子策略

1. isolated-research(隔离研究)

特点

  • 在子代理中执行,不污染主上下文
  • 一次性任务,快速返回
  • 适合聚焦的单一问题

详细指南参阅 isolated-research.md

2. iterative-retrieval(迭代检索)

特点

  • 多轮迭代,逐步精炼
  • 置信度评估驱动
  • 适合复杂跨模块问题

详细指南参阅 iterative-retrieval.md


与角色系统配合

角色 探索场景 推荐策略
/pm 理解现有功能 isolated-research
/lead 架构分析、技术设计 iterative-retrieval
/dev 实现前了解相关代码 isolated-research
/qa 理解测试范围 isolated-research
/debug 追踪 Bug 根因 iterative-retrieval

最佳实践

  1. 先评估再选择 - 根据问题复杂度选择策略
  2. 记录路径 - 始终包含文件路径和行号
  3. 限制范围 - 明确探索边界,避免发散
  4. 输出结构化 - 使用统一格式便于后续使用
  5. 复用结果 - 探索结果可保存到 memory-bank

核心理念:探索是理解的基础,好的探索策略能显著提升开发效率。
