# A股股票聚类/相似股票发现
## 数据源
```bash
SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts"
python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [日期]
python "$SCRIPTS/cn_stock_data.py" quote --code [CODE]
python "$SCRIPTS/cn_stock_data.py" finance --code [CODE]
```
## Workflow
### Step 1: 获取多股数据
### Step 2: 特征构建
- 收益率特征:日/周收益率序列
- 基本面特征:PE/PB/ROE/营收增速等
- 技术特征:波动率/Beta/动量等
### Step 3: 聚类分析
- K-Means聚类(需指定K)
- 层次聚类(树状图可视化)
- DBSCAN(自动发现簇数)
### Step 4: 簇特征分析
各簇的共同特征(行业/风格/基本面)
### Step 5: 输出
| 维度 | formal | brief |
|------|--------|-------|
| 聚类结果 | 完整分簇列表 | 目标股所在簇 |
| 簇特征 | 各簇详细画像 | 同类股票 |
| 应用 | 配对交易候选 | Top 5相似股 |
默认风格:brief。
## 关键规则
1. 特征标准化是聚类的前提——不同量纲需归一化
2. K-Means对K值敏感——可用肘部法则或轮廓系数选K
3. 收益率相似不等于基本面相似——需分维度聚类
4. 聚类结果可用于配对交易候选筛选
5. 行业分类≠统计聚类——后者可能发现隐含关联
## 使用示例
### 示例 1: 基本使用
```python
# 调用 skill
result = run_skill({
"param1": "value1",
"param2": "value2"
})
```
### 示例 2: 命令行使用
```bash
python scripts/run_skill.py --input data.json
```

Playbook for creating and editing uCoz landing pages via MCP tools (`templates_tool`, `ftp_tool`, `modules_tool`). Use for tasks such as: "build a landing page", "update the homepage as a landing page", "create a promo page on the homepage", "add a lead form / menu / SEO to the homepage". Homepage: `page_list`, `page_get`; first publish — `page_update` with full `page_tmpl`; HTML edits after generation — `patch_template` (module_id=2, template_id=1), not `update_template`.

Interact with the Paperclip control plane API to manage tasks, coordinate with other agents, and follow company governance. Use when you need to check assignments, update task status, delegate work, post comments, set up or manage routines (recurring scheduled tasks), or call any Paperclip API endpoint. Do NOT use for the actual domain work itself (writing code, research, etc.) — only for Paperclip coordination.
