# Okane Skills - 残高予測・シミュレーション
## 概要
[okane](https://okane-nine.vercel.app/)のエクスポートJSONを分析し:
- **将来の残高予測** - Xヶ月後にいくらになるか
- **出費可否チェック** - 大きな出費が間に合うか
- **危険ポイント検出** - 残高不足になる日を警告
- **ログ圧縮** - 古いデータを月次サマリーに圧縮
## 主要機能
### 1. 残高予測 (`--forecast N`)
Nヶ月後までの残高推移と、各月の大きな出入り（10万円以上）を表示。
```bash
python scripts/okane_analyzer.py data.json --forecast 6
```
**出力例:**
| 月 | 残高 | 大きな出入り |
|----|------|-------------|
| 2026-01 | ¥1,500,000 | 給与(+¥300,000), カード(-¥150,000) |
| 2026-02 | ¥1,200,000 | 家賃(-¥100,000) |
### 2. 出費可否チェック (`--check AMOUNT`)
「この日にこの金額使って大丈夫？」を判定。
```bash
python scripts/okane_analyzer.py data.json --check 1000000 --date 2026-02-01
```
**出力:**
- 判定（✅可能 / ⚠️ギリギリ / ❌不足）
- 出費前後の残高
- その後の予定支出一覧
### 3. 危険ポイント検出 (`--danger`)
残高が閾値を下回る日を検出。
```bash
python scripts/okane_analyzer.py data.json --danger --threshold 100000
```
### 4. ログ圧縮 (`--compress`)
古い取引を月次サマリーに圧縮してファイルサイズを削減。
```bash
python scripts/okane_analyzer.py data.json --compress --keep-months 3 -o compressed.json
```
- `--keep-months N`: 直近Nヶ月は詳細を保持（デフォルト: 3）
- 圧縮前: 各取引が個別レコード
- 圧縮後: 月ごとの収入合計・支出合計に集約
### 5. グラフ生成 (`--chart`)
残高推移グラフをPNG画像で出力。
```bash
python scripts/okane_analyzer.py data.json --chart --chart-months 6 -o chart.png
```
**グラフの内容:**
- 青線: 残高推移
- 緑縦線: 今日
- ▲緑マーカー: 大きな収入（20万円以上）
- ▼赤マーカー: 大きな支出（20万円以上）
## JSONデータ形式
```json
{
"version": "1.0",
"initialBalance": 0,
"transactions": [
{
"id": "unique-id",
"date": "YYYY-MM-DD",
"type": "income" | "expense",
"amount": number,
"description": "説明"
}
]
}
```
## 典型的な使い方
1. **「3月に100万使いたいけど大丈夫？」**
→ `--check 1000000 --date 2026-03-01`
2. **「半年後の貯金いくら？」**
→ `--forecast 6`
3. **「お金やばくなる時ある？」**
→ `--danger`
4. **「JSONが重くなってきた」**
→ `--compress`
5. **「グラフで見せて」**
→ `--chart -o chart.png`Related Skills

skills-discovery
Search for and install Agent Skills that give you specialized capabilities. Before starting work, ask might a skill exist that handles this better than my base knowledge? If the task involves specific technologies, frameworks, file formats, or expert domains. Search proactively, even if the user doesn't mention skills. Skills encode best practices, tools, and techniques you wouldn't otherwise have. Also use when users explicitly ask to find, install, or manage skills.
