Requirements

  • curl - Command-line HTTP client
  • python3 - For URL encoding

Security Features

This skill includes several security enhancements:

1. Input Sanitization

Removes dangerous shell metacharacters that could be exploited:

sanitize_input() {
    local input="$1"
    echo "$input" | sed 's/[^a-zA-Z0-9 \_\-\.\~\x{4e00}-\x{9fff}]//g'
}

2. Command Injection Protection

  • Validates search engine selection
  • Restricts max results to 1-50
  • Checks for empty input after sanitization

3. URL Encoding

Uses Python's urllib.parse with safe='' parameter to properly encode special characters.

Installation

# Install via ClawHub
clawhub install curl-search

# Or manually
cd your-skills-dir
tar -xzf curl-search.tar.gz

Configuration

export SEARCH_ENGINE=google

Set max results:

export MAX_RESULTS=5

Limitations

  • Search results come from public search engines
  • May be blocked by anti-scraping measures
  • Google requires proxy/VPN in China
