Pre-Install Hook (Block Suspicious Skills)

Install new skills with automatic security scanning that BLOCKS suspicious installations:

Quick Install with Scan

# Interactive mode (asks before installing)
bash /root/clawd/skills/security-skill-scanner/install-skill.sh nano-banana-pro

# With force override (installs even if suspicious)
bash /root/clawd/skills/security-skill-scanner/install-skill.sh suspicious-skill --force

# Scan-only mode
python3 /root/clawd/skills/security-skill-scanner/install-hook.py skill-name --scan-only

Integration with molthub

Add to your shell profile for automatic scanning on every install:

# Add to ~/.bashrc or ~/.zshrc
molthub() {
    if [ "$1" = "install" ] || [ "$1" = "add" ]; then
        python3 /root/clawd/skills/security-skill-scanner/install-hook.py "$2" --interactive
    else
        /home/linuxbrew/.linuxbrew/bin/molthub "$@"
    fi
}

Now every molthub install <skill> will be scanned first!

What Happens

1. Clean skill → Installs normally ✅
2. Whitelisted skill → Installs normally ✅
3. Suspicious skill → BLOCKED with explanation 🚫
4. Suspicious + --force → Warns but installs ⚠️
