## 使い方

```bash
# 基本リサーチ
/research-free AIエージェントの最新動向

# クイック検索(5件程度)
/research-free Next.js 15 新機能 --depth=quick

# 標準リサーチ(10-15件)
/research-free 生成AI市場 --depth=standard

# 深層リサーチ(20件以上)
/research-free 量子コンピューティング投資 --depth=deep
```

## 実行フロー

### 1. WebSearch で情報収集

```
WebSearch(query="トピック + 最新")
WebSearch(query="トピック + とは")
WebSearch(query="トピック + 比較")
WebSearch(query="トピック + メリット デメリット")
```

### 2. 重要URLをWebFetchで詳細取得

```
WebFetch(url="重要そうなURL", prompt="要点を抽出")
```

### 3. 統合・分析

- 複数ソースからの情報をクロスチェック
- 矛盾点を特定
- 信頼度を評価

### 4. レポート出力

```markdown
# [トピック] 調査レポート

## 要約
- ポイント1
- ポイント2

## 主要な発見
### 発見1
[内容]
**出典**: [URL]

## 出典一覧
1. [タイトル](URL)
```

## 深度別の検索パターン

### quick(5件程度)
```
1. "[トピック] 2026" → 最新情報
2. "[トピック] とは" → 基本情報
```

### standard(10-15件)
```
1. "[トピック] 2026 最新"
2. "[トピック] とは わかりやすく"
3. "[トピック] メリット デメリット"
4. "[トピック] 比較"
5. "[トピック] 始め方"
```

### deep(20件以上)
```
1-5. standard の検索
6. "[トピック] 事例"
7. "[トピック] 失敗"
8. "[トピック] 成功"
9. "[トピック] 注意点"
10. "[トピック] 将来性"
11. "[トピック] 市場規模"
12. "[トピック] 競合"
+ 重要URLのWebFetch詳細取得
```

## API版との比較

| 機能 | research-free | mega-research (API版) |
|------|--------------|----------------------|
| **APIキー** | 不要 ✅ | 必要 |
| **配布時** | そのまま動作 ✅ | 設定必要 |
| **検索精度** | 良好 | 高精度 |
| **検索速度** | 標準 | 高速(並列) |
| **ニュース** | WebSearch経由 | NewsAPI直接 |
| **コミュニティ** | WebSearch経由 | Reddit API直接 |
| **AI要約** | Claude分析 | Perplexity |

## 制限事項

1. **レート制限**: WebSearchは連続使用で制限される場合あり
2. **リアルタイム性**: ニュースAPIほどのリアルタイム性はない
3. **構造化データ**: SerpAPIのような構造化結果は得られない

## ベストプラクティス

1. **具体的なクエリ**
   - ❌ "AI"
   - ✅ "2026年 AIエージェント 市場動向"

2. **年を含める**
   - 最新情報が必要な場合は「2026」を追加

3. **複数の観点**
   - 「メリット」「デメリット」「比較」など複数視点で検索

## 出力ディレクトリ

research-web

16
from diegosouzapw/awesome-omni-skill

Deep web research with parallel investigators, multi-wave exploration, and structured synthesis. Spawns multiple web-researcher agents to explore different facets of a topic simultaneously, launches additional waves when gaps are identified, then synthesizes findings. Use when asked to research, investigate, compare options, find best practices, or gather comprehensive information from the web.\n\nThoroughness: quick for factual lookups | medium for focused topics | thorough for comparisons/evaluations (waves continue while critical gaps remain) | very-thorough for comprehensive research (waves continue until satisficed). Auto-selects if not specified.
