# OpenClaw Traditional Chinese Dictionary Skill

## Installation

This skill requires Python dependencies. Install them with `uv`:

```bash
# Install dependencies (recommended: use uv for faster installation)
uv pip install -r requirements.txt

# Alternative: use pip if uv is not available
pip install -r requirements.txt
```

**Required packages:**
- `pandas>=2.0.0` — Data processing
- `openpyxl>=3.1.0` — Excel file reading

## Security

This skill implements the following security measures:

✅ **TLS Certificate Verification** — All HTTPS connections to MOE servers use proper SSL/TLS certificate validation (no disabled verification)

✅ **Zip-Slip Protection** — Dictionary downloads validate all zip file paths before extraction to prevent directory traversal attacks (path validation applied)

✅ **Safe File Handling** — Extracted files are validated and stored in user-isolated directory (`~/.openclaw/dictionaries/`)

⚠️ **Cron/Automatic Updates** — If you enable automatic updates via cron, the skill will download dictionary files from MOE on your specified schedule. Consider the frequency and enable notifications to track changes.

## Overview

This skill enables you to query Traditional Chinese dictionaries published by Taiwan's Ministry of Education. It provides:

- **Word lookup** — Search for word definitions with automatic fuzzy matching
- **Dictionary management** — Download, extract, and version-control dictionary data
- **Update automation** — Automatic periodic checks (cron) + manual update requests
- **Extensible design** — Currently supports "國語辭典簡編本" (Concised Dictionary), with room for other MOE dictionaries in the future

## Core Capabilities

### 1. Query Words

Users can look up words using natural language like:
- "請告訴我『蒼鷺』的意思" (Tell me the meaning of '蒼鷺')
- "查『梅雨』" (Look up '梅雨')
- "『破曉』是什麼意思？" (What does '破曉' mean?)

The skill returns the primary definition first. If the user asks for details, provide:
- Full definition
- Examples/usage
- Related information from the dictionary

**Implementation**: See `query_dictionary.py` for the search logic.

### 2. Manage Dictionary Updates

Users can trigger updates in two ways:

**Manual update:**
- "更新字典" (Update dictionary)
- "重新下載國語辭典" (Re-download the dictionary)

**Automatic update (cron):**
- Set up a cron job to check for updates monthly
- Compare local version (stored in metadata.json) against MOE's latest version
- Download and extract only if a newer version exists

**Implementation**: See `download_dictionary.py` for download/extraction logic and `check_updates.py` for version management.

## Configuration

The skill respects a configuration file at `~/.openclaw/dictionaries/config.json`:

```json
{
  "storage_path": "~/.openclaw/dictionaries",
  "auto_update_interval_days": 30,
  "dictionaries": {
    "concised": {
      "enabled": true,
      "name": "國語辭典簡編本",
      "source": "https://language.moe.gov.tw/001/Upload/Files/site_content/M0001/respub/dict_concised_download.html"
    }
  }
}
```

Users can customize `storage_path` to store dictionaries elsewhere. The default is `~/.openclaw/dictionaries/`.

## Usage Examples

### Example 1: Simple word lookup
```
User: "請告訴我『藍寶石』的意思"
Response: 藍寶石：寶石名。紅玉髓的一種。（如需詳細資料，請告訴我）
```

### Example 2: Request with details
```
User: "『藍寶石』是什麼意思？告訴我更多"
Response: 藍寶石：寶石名。紅玉髓的一種。
例句：...
相關詞語：...
```

### Example 3: Manual update
```
User: "更新字典"
Response: 正在檢查最新版本...
當前版本：2025-12-29
最新版本：[Latest from MOE]
[如果有更新] 已更新字典至最新版本 (2025-12-29)
[如果無更新] 字典已是最新版本
```
