Claude Code Safety Net

Name: Claude Code Safety Net (Claude Skill)
Author: kenryu42

제작: kenryu42 · kenryu42/claude-code-safety-net

A hooks-driven safety net for Claude Code — interceptors catch rm -rf, git reset --hard, force pushes, and uncommitted destructive edits.

Installs as a Claude Code plugin with PreToolUse hooks. Each potentially destructive operation is intercepted and either confirmed or refused based on rules. Includes rules for git, file system, npm, and arbitrary bash.

설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "claude-code-safety-net": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/kenryu42/claude-code-safety-net",
        "~/.claude/skills/safety-net"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "claude-code-safety-net": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/safety-net"
      ],
      "_inferred": true
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "claude-code-safety-net": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/kenryu42/claude-code-safety-net",
        "~/.claude/skills/safety-net"
      ],
      "_inferred": true
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "claude-code-safety-net": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/kenryu42/claude-code-safety-net",
        "~/.claude/skills/safety-net"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "claude-code-safety-net",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/kenryu42/claude-code-safety-net",
        "~/.claude/skills/safety-net"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "claude-code-safety-net": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/kenryu42/claude-code-safety-net",
          "~/.claude/skills/safety-net"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add claude-code-safety-net -- git clone https://github.com/kenryu42/claude-code-safety-net ~/.claude/skills/safety-net

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

→ Skill directory present
Wire hooks

Run the included setup; settings.json gets PreToolUse entries.✓ 복사됨

→ Hooks active
Test

Ask Claude to git reset --hard; expect block.✓ 복사됨

→ Block triggered

결과: Destructive ops require explicit override.
