Hooks 实战应用

应用1: 自动代码审查

创建 .claude/hooks/review.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Edit|Write",
        "hooks": [
          {
            "type": "command",
            "command": "npx eslint --no-error-on-uncaught ${file}"
          }
        ]
      }
    ]
  }
}

效果: 每次编辑或写入文件后,自动运行 ESLint 检查

应用2: 自动格式化

创建 .claude/hooks/format.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Edit|Write",
        "hooks": [
          {
            "type": "command",
            "command": "npx prettier --write ${file}"
          }
        ]
      }
    ]
  }
}

效果: 保存文件时自动格式化代码

应用3: 发送通知

创建 .claude/hooks/notify.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "echo '✅ 匽令执行完成: ${command}'"
          }
        ]
      }
    ]
  }
}
