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.
