instructions: |

Use this skill to analyze git history for development insights. For --hotspots mode,

rank files by modification frequency to identify change hotspots (potential tech debt).

For --contributors mode, analyze per-contributor statistics (commits, lines changed,

active periods). For --churn mode, analyze code addition/deletion ratios for stability

assessment. For --coupling mode, find files that are frequently modified together

(temporal coupling). Always provide actionable recommendations based on the analysis.

examples:

- input: "/git-history-analyzer --hotspots"

output: "Top hotspots: 1) index.js (87 changes), 2) database.js (45 changes), 3) session-manager.js (38 changes). These files may benefit from refactoring."

- input: "/git-history-analyzer --contributors"

output: "3 contributors: Alice (234 commits, 12k lines), Bob (156 commits, 8k lines). Active hours: 09:00-18:00 UTC."

- input: "/git-history-analyzer --churn"

output: "High churn files: auth.js (added 500, deleted 480 = 96% churn), config.js (added 200, deleted 180). These indicate unstable code."

- input: "/git-history-analyzer --coupling"

output: "Coupled pairs: (database.js, migration.js) 85% co-change, (auth.js, session.js) 72% co-change. Consider merging or extracting shared logic."

# Git History Analyzer 技能

## 描述

分析 Git 提交历史，识别变更热点、贡献者模式、代码流失率和文件耦合关系。灵感来自 code-maat 和 git-of-theseus。

## 使用方法

```

/git-history-analyzer [选项]

```

## 分析维度

### 变更热点 (--hotspots)

按文件修改频率排序，识别最常变更的文件

### 贡献者分析 (--contributors)

每人修改行数/文件数/活跃时段

### 代码流失 (--churn)

新增vs删除比率，文件稳定性评估

### 耦合检测 (--coupling)

经常一起修改的文件对
