设置 Git 防护栏

SkillAI & models

Sets up Claude Code hooks to intercept dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when the user wants to block destructive git operations, add git safety hooks, or intercept git push/reset in Claude Code.

设置一个 PreToolUse 钩子,在 Claude 执行危险的 git 命令之前将其拦截并阻止。

哪些命令会被阻止

  • git push(包括 --force 在内的所有变体)
  • git reset --hard
  • git clean -f / git clean -fd
  • git branch -D
  • git checkout . / git restore .

被阻止时,Claude 会看到一条消息,告知它无权访问这些命令。

步骤

1. 询问适用范围

询问用户:只为当前项目安装(.claude/settings.json),还是为所有项目安装(~/.claude/settings.json)?

2. 复制钩子脚本

随附脚本位于:scripts/block-dangerous-git.sh

根据适用范围将其复制到目标位置:

  • 项目级:.claude/hooks/block-dangerous-git.sh
  • 全局级:~/.claude/hooks/block-dangerous-git.sh

用 chmod +x 赋予可执行权限。

3. 在设置中添加钩子

添加到相应的设置文件:

项目级(.claude/settings.json):

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh"
          }
        ]
      }
    ]
  }
}

全局级(~/.claude/settings.json):

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "~/.claude/hooks/block-dangerous-git.sh"
          }
        ]
      }
    ]
  }
}

如果设置文件已存在,将该钩子合并进现有的 hooks.PreToolUse 数组——不要覆盖其他设置。

4. 询问是否自定义

询问用户是否想从阻止列表中添加或移除某些模式。相应地编辑复制后的脚本。

5. 验证

运行一个快速测试:

echo '{"tool_input":{"command":"git push origin main"}}' | <path-to-script>

应以退出码 2 退出,并向 stderr 打印一条 BLOCKED 消息。
