Map — Codebase Symbol Map

SkillFiles & storage

Generates a semantic symbol map of the codebase (precise file:line locations of classes, functions, interfaces, and types). Ideal before large refactors or when taking over an unfamiliar codebase.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Map — Codebase Symbol Map skill

What this skill tells your AI

The instructions your AI receives, as published by zeuikli/claude-code-workspace in .claude/skills/map/SKILL.md and read by ahel’s review.

觸發條件

  • 開始大規模重構前,需要精確的符號位置
  • 接手陌生 codebase,需要快速建立心智地圖
  • 避免 Grep 在註解/字串中找到誤報
  • prime skill 搭配:prime 讀 README,map 產出符號索引

執行方式

# 在專案根目錄執行(輸出存於 ~/.claude/codebase-maps/)
python3 ~/.claude/skills/map/scripts/symbol_map.py

# 或指定目標目錄
python3 ~/.claude/skills/map/scripts/symbol_map.py /path/to/project

腳本會:

  1. 自動偵測語言(TypeScript / JavaScript / Python / Rust / Go)
  2. 提取所有 exported 符號與精確 file:line
  3. 輸出 markdown 地圖至 ~/.claude/codebase-maps/<project>_symbols.md

輸出格式範例

# Codebase Symbol Map

**Project**: `my-project`
**Languages**: typescript
**Files**: 42 | **Symbols**: 183

## Classes
| Symbol | Location |
|--------|----------|
| `AuthProvider` | `src/auth/provider.ts:15` |

## Functions
| Symbol | Location |
|--------|----------|
| `formatDate` | `src/utils/date.ts:42` |

產出後的使用方式

地圖生成後,直接引用精確位置:

  • 「讀 src/auth/provider.ts:15 確認 AuthProvider 的介面」
  • src/utils/date.ts:42formatDate 需要修改」

不再需要猜測或用 Grep 反覆搜尋。

支援語言

語言提取符號類型
TypeScriptfunction, class, interface, type, const, enum
JavaScriptfunction, class, const, module.exports
Pythonclass, def, TypeVar
Rustpub fn, pub struct, pub enum, pub trait
Goexported func, struct, interface (大寫開頭)

Gotcha

  • 腳本路徑:確認 ~/.claude/skills/map/scripts/symbol_map.py 存在(在 workspace 的 .claude/skills/map/scripts/ 目錄中)
  • 輸出目錄:地圖存於 ~/.claude/codebase-maps/,非 workspace 目錄,不會被 git 追蹤
  • 大型 codebase:超過 1000 個檔案時產出可能較大;用 head -100 先看摘要
  • 動態語言:Python 只提取頂層 class/def,不含動態建立的符號
  • 更新時機:每次大規模重構後重跑更新地圖
