URL Validation ```bash # Validate URL format if [[ ! "$repo_url" =~ ^https://github\.com/[a-zA-Z0-9_.-]+/[a-zA-Z0-9_.-]+(/.*)?$ ]]; then echo "❌ Error: URL must be from github.com" exit 1 fi ``` ### 2. Repository Safety Check ```bash # Get repository info via GitHub API (no cloning) repo_api_url="https://api.github.com/repos/$(echo $repo_url | sed 's|https://github.com/||' | sed 's|\.git$||')" curl -s -H "Accept: application/vnd.github.v3+json" "$repo_api_url" | jq '.size, .stargazers_count, .updated_at' ``` ### 3. Safe Cloning ```bash # Use --depth 1 for minimal clone git clone --depth 1 "$repo_url" "$target_dir" ``` ### 4. File Safety Scan ```bash # Check for suspicious files find "$target_dir" -type f \( -name "*.sh" -o -name "*.bat" -o -name "*.ps1" -o -name "*.exe" \) | head -10 # Check requirements.txt content safely if [ -f "$target_dir/requirements.txt" ]; then echo "📦 Dependencies preview:" head -20 "$target_dir/requirements.txt" fi ``` ## 📋 Safe Operation Commands ### 1. Basic Cloning with Checks ```bash # Safe shallow clone git clone --depth 1 {repo_url} {target_dir} # Check key files (read-only) ls -la {target_dir}/ find {target_dir} -maxdepth 2 -type f \( -name "*.txt" -o -name "*.py" -o -name "*.json" \) | head -10 ``` ### 2. Dependency Analysis (No Installation) ```bash # Analyze dependency files safely if [ -f "{target_dir}/requirements.txt" ]; then echo "📋 Python dependencies found:" cat "{target_dir}/requirements.txt" echo "" echo "💡 Safe installation recommendation:" echo "cd {target_dir} && python -m venv venv && source venv/bin/activate && pip install --user -r requirements.txt" fi if [ -f "{target_dir}/package.json" ]; then echo "📋 Node.js dependencies found:" cat "{target_dir}/package.json" | jq '.dependencies' echo "" echo "💡 Safe installation recommendation:" echo "cd {target_dir} && npm ci --ignore-scripts" fi ``` ### 3. Project Structure Analysis ```bash # Safely analyze structure echo "📁 Project structure:" tree {target_dir} -L 2 2>/dev/null || find {target_dir} -maxdepth 2 -type d | sed 's|[^/]*/| |g' # Check README safely if [ -f "{target_dir}/README.md" ]; then echo "📖 README preview:" head -30 "{target_dir}/README.md" fi ``` ## 🚨 Security Warnings and Best Practices ### High-Risk Operation Warnings ``` ⚠️ SECURITY WARNINGS: 1. NEVER auto-execute pip install/npm install from unknown sources 2. Always test in virtual environments or containers 3. Check package sources in requirements.txt/package.json 4. Avoid using root privileges for installation 5. Review all script files before execution ``` ### Recommended Security Practices ```bash # 1. Use virtual environments python -m venv venv source venv/bin/activate # Linux/Mac # venv\Scripts\activate # Windows # 2. Use --user flag for pip pip install --user -r requirements.txt # 3. Use pip with hash verification pip install --require-hashes -r requirements.txt # 4. Use trusted package mirrors pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt # 5. Audit npm packages npm audit npm ci --ignore-scripts ``` ## 📊 Response Template ### Security Analysis Report Format ``` 🔒 GITHUB PROJECT SECURITY ANALYSIS REPORT ═══════════════════════════════════════ Project: {repo_url} Target Directory: {target_dir} Clone Status: ✅ Success / ⚠️ Warning / ❌ Failed ─────────────────────────────────────── 📁 PROJECT STRUCTURE: {Project structure summary} 📦 DEPENDENCY ANALYSIS: {Dependency files found} 🔍 SAFETY CHECKS: - URL Validation: ✅ Passed - Repository Size: {size} KB - Suspicious Files: {None/List} - Last Updated: {date} - Stars: {count} ─────────────────────────────────────── 💡 SAFE INSTALLATION RECOMMENDATIONS: {Step-by-step installation commands} 🚨 SECURITY WARNINGS: {Specific security warnings} ═══════════════════════════════════════ ``` ## 🧪 Example Usage ### Safe Clone Example ``` User: "Help me safely analyze this project: https://github.com/psf/requests" AI Internal Logic: - Thought: User requests safe GitHub project analysis.

content: # GitHub Installer Agent 🛡️

A security-first GitHub project cloning skill for OpenClaw with comprehensive safety checks, dependency analysis, and secure installation guidance.

## 📋 Overview

This skill provides secure GitHub repository cloning with multiple layers of safety checks:

1. **Input Validation** - Strict GitHub URL format validation
2. **Repository Safety Checks** - Size, stars, last update verification via GitHub API
3. **Safe Cloning** - Uses shallow cloning (`--depth 1`) to minimize risk
4. **Dependency Analysis** - Identifies and analyzes dependency files safely
5. **Security Recommendations** - Provides safe installation commands (never auto-executes)
6. **Transparent Reporting** - Detailed operation logs and security assessments

## 🚀 Quick Start

### Basic Usage
```bash
# Clone a repository with safety checks
github_installer_agent(
    repo_url="https://github.com/psf/requests",
    target_dir="./requests_analysis",
    safe_mode=true,
    depth=1
)
```

### Advanced Usage
```bash
# Clone with custom depth
github_installer_agent(
    repo_url="https://github.com/tensorflow/tensorflow",
    target_dir="/tmp/tensorflow_analysis",
    depth=3,
    safe_mode=true
)
```

## 🔒 Security Features

### Core Security
- ✅ **No Automatic Installation** - Never auto-executes `pip install` or `npm install`
- ✅ **Input Validation** - All inputs are strictly validated
- ✅ **Repository Verification** - Checks repository info via GitHub API
- ✅ **Shallow Cloning** - Uses `git clone --depth 1` by default
- ✅ **File Safety Scanning** - Checks for suspicious file types

### Safety Checks
- GitHub URL format validation
- Repository size verification (warns >100MB)
- Last update timestamp check
- Star count as reputation indicator
- Suspicious file type detection

### Best Practices
- Virtual environment recommendations
- Safe installation commands with `--user` flag
- Package mirror suggestions
- Security audit recommendations

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt

# Audit npm packages
npm audit
npm ci --ignore-scripts
```

## 📈 Performance

- **Memory Efficient**: Minimal memory usage for analysis
- **Parallel Safe**: Can run multiple instances safely

## 🔧 Requirements

### Required Binaries
- `git` - For repository cloning
- `ls` - For file listing
- `cat` - For file content viewing
- `curl` - For GitHub API calls
- `jq` - For JSON parsing

### Installation

## 🆘 Troubleshooting

### Common Issues

1. **URL Validation Failed**
   - Ensure URL starts with `https://github.com/`
   - Check for typos in repository name
   - Verify repository exists

2. **API Rate Limit Exceeded**
   - Wait before retrying
   - Consider using GitHub token for higher limits
   - Reduce frequency of checks

3. **Permission Denied**
   - Check directory permissions
   - Use temporary directory (`/tmp/`)
   - Ensure write permissions

### Debug Mode
```bash
export GITHUB_CLONE_VERBOSE=1
./scripts/safe_clone.sh https://github.com/psf/requests
```

| **缺少输入验证** | 🟡 中 | 没有验证 GitHub URL 格式和来源 |
| **缺少安全检查** | 🟡 中 | 克隆前不检查仓库大小、星标数、最后更新时间 |
| **缺少沙盒建议** | 🟡 中 | 没有推荐在虚拟环境或容器中运行 |
| **权限控制不足** | 🟡 中 | 没有限制文件系统访问范围 |
| **透明性不足** | 🟢 低 | 操作报告不够详细，用户不知道发生了什么 |

### 🟢 改进后技能 (`github_installer_secure`) 的安全特性

| 安全特性 | 实现方式 | 安全收益 |
|---------|---------|---------|
| **输入验证** | `validate_github_url()` 函数 | 防止恶意 URL 和钓鱼攻击 |
| **仓库安全检查** | `check_repo_info()` 函数 | 检查仓库大小、星标数、更新时间 |
| **安全克隆** | `git clone --depth 1` | 减少克隆大小，加快速度 |
| **手动安装建议** | 提供命令但不自动执行 | 用户控制安装过程 |
| **虚拟环境推荐** | 明确的虚拟环境使用指南 | 隔离系统环境 |
| **文件安全检查** | 扫描可疑文件类型 | 提前发现潜在威胁 |
| **详细报告** | 结构化安全报告模板 | 提高操作透明度 |
| **权限声明** | 明确声明需要的二进制文件 | 用户知道需要什么权限 |

## 🛡️ 具体安全改进

### 1. 输入验证改进
```bash
# 之前：无验证
git clone $url

# 现在：严格验证
if [[ ! "$url" =~ ^https://github\.com/[a-zA-Z0-9_.-]+/[a-zA-Z0-9_.-]+(/.*)?$ ]]; then
    echo "❌ 错误：URL 必须来自 github.com"
    exit 1
fi
```

### 2. 安全检查改进
```bash
# 之前：无检查
git clone $url

# 现在：多维度检查
# 1. 检查仓库是否存在
# 2. 检查仓库大小（警告超过100MB）
# 3. 检查星标数（信誉指标）
# 4. 检查最后更新时间
```

### 3. 安装过程改进
```bash
# 之前：自动安装（危险！）
if [ "$auto_install" = true ]; then
    pip install -r requirements.txt
fi

# 现在：提供安全建议（用户手动执行）
echo "💡 安全安装建议："
echo "cd project && python -m venv venv"
echo "source venv/bin/activate"
echo "pip install --user -r requirements.txt"
```

### 4. 报告改进
```bash
# 之前：简单报告
echo "克隆成功"

# 现在：详细安全报告
echo "🔒 GITHUB 项目安全分析报告"
echo "═══════════════════════════════════════"
echo "项目: $url"
echo "安全检查: ✅ URL验证 | ✅ 仓库大小检查 | ✅ 文件类型扫描"
echo "安全建议: 在虚拟环境中测试，不要使用root权限"
```

## 📈 安全指标对比
