多文件差异预览器 - 在应用AI变更前展示丰富的diff预览，支持部分接受和变更地图.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 差异预览器技能
## 描述
多文件差异预览器，在应用AI变更前提供丰富的diff预览。支持查看git暂存/未暂存差异、比较任意两个文件、生成变更统计和变更地图。提供token估算帮助优化AI上下文窗口使用。
## 使用方法
```
/diff-previewer <mode> [arguments]
```
## 模式
| 模式 | 说明 |
| ------------ | ---------------------------------------- |
| `--staged` | 显示git暂存区的差异（git diff --cached） |
| `--unstaged` | 显示工作区未暂存的差异（git diff） |
| `--compare` | 比较两个指定文件的差异 |
| `--stats` | 显示变更统计，包含目录级别的分解 |
| `--summary` | 紧凑的token高效摘要，适合注入AI上下文 |
## 输出格式
### 结构化差异
```json
{
"files": [
{
"path": "src/main/index.js",
"status": "M",
"additions": 15,
"deletions": 3,
"hunks": [
{
"oldStart": 10,
"oldCount": 5,
"newStart": 10,
"newCount": 17,
"lines": ["..."]
}
]
}
],
"totalAdditions": 15,
"totalDeletions": 3,
"tokenEstimate": 450
}
```
### 变更地图
```
src/main/
index.js ████░░░░░░ +15 -3
database.js ██████████ +42 -10
src/renderer/
App.vue ██░░░░░░░░ +5 -1
```
## 示例
查看暂存的变更：
```
/diff-previewer --staged
```
查看未暂存的变更：
```
/diff-previewer --unstaged
```
比较两个文件：
```

How to install
mdr add chainlesschain/chainlesschain/diff-previewer@sha256:9d4819e04c1355dbThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
