# Send 4D Compression Core to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

### 🌀 4D Compression Core - 4D 向量压缩

把长内容压缩成结构化向量——节省 60-80% Token，保留核心信息

### 🎯 核心功能

🧠 结构化压缩 - 四维分离，结构化压缩
📊 智能压缩 - 自动识别核心信息，删除冗余内容
🎯 语义保留 - 保留核心语义，压缩率 60-80%
📚 书籍处理 - EPUB/PDF书籍自动压缩

### 🚀 快速开始

压缩文本

你说："压缩这段内容"

Neo 显示：
🌀 4D 压缩完成

原始：12,345 tokens
压缩后：3,456 tokens
节省：72%

【结构化要点】核心信息...

💡 保留核心语义，可安全使用

处理书籍

你说："处理这本 EPUB"

Neo 显示：
🌀 书籍压缩完成

输入：《重塑心灵》(12 章，500KB)
输出：
  - 压缩版：120KB（节省 76%）
  - 完整版：500KB（原始内容）

💡 压缩版适合快速阅读，完整版适合深度研究

### 🎯 触发词（随口一说就懂）

你想做什么你说压缩文本"压缩"、"4d"、"精简"、"compress"处理书籍"处理 EPUB"、"压缩这本书"、"PDF 压缩"

不用配置，说"压缩"就启动。

### 📦 安装

clawhub install 4d-compression-core

### ⚠️ 安全与边界

压缩率

文本：60-80%（因内容而异）
书籍：70-80%（实测）

语义保留

压缩版：保留核心语义
完整版：100% 原始内容（备查）

不过度承诺

压缩率因内容而异
诗歌、小说等创意内容压缩率可能较低

### 🫂 写在最后

我们设计这个技能，是因为我们知道：

长内容费 Token，但你不想丢失核心信息。

你想快速抓住重点，但不想读完全文。

所以我们做了这个——

把长内容压缩成结构化向量，节省 60-80% Token。

不用读全文，核心信息一目了然。
