Claude Code 的自訂 Agents 功能讓你可以為特定任務建立專用的 AI 助手。本文精選 10 個最實用的 Agents，每個都可以直接複製使用。

快速入門

安裝

  1. 在專案目錄建立 .claude/agents/ 資料夾
  2. 將下方的 Agent 內容存成 .md 檔案
  3. 重新啟動 Claude Code
mkdir -p .claude/agents
# 將 Agent 內容儲存到對應的檔案

使用方式

Claude 會依據任務自動選擇合適的 Agents，你也可以直接指定：

## 成本優化指南

### 模型選擇策略

| 任務類型 | 建議模型 | 原因 |
|----------|----------|------|
| 程式碼搜尋 | Haiku | 快速、便宜 |
| 文件撰寫 | Haiku | 不需要複雜推理 |
| Git 操作 | Haiku | 流程固定 |
| 程式碼審查 | Sonnet | 需要深度分析 |
| 除錯 | Sonnet | 需要推理能力 |
| 資安稽核 | Sonnet | 不能出錯 |
| 關鍵決策 | Opus | 最高品質 |

### 費用比較

| 模型 | 相對費用 | 速度 |
|------|----------|------|
| Haiku 4.5 | 1x | 最快 |
| Sonnet 4.5 | 3x | 中等 |
| Opus 4.5 | 15x | 最慢 |

### 最佳實踐

1. **預設使用 Haiku**：簡單任務不需要大型模型
2. **核心任務用 Sonnet**：程式碼審查、除錯、重構
3. **Opus 留給關鍵時刻**：重大架構決策
