WHY IT NEEDS A POLICY

Why virustotal_scan_url needs a policy

This tool triggers an external operation (submitting a URL to VirusTotal's scanning service). It executes an action on a third-party platform whose effects depend on the URL argument provided. It is not purely read-only since it initiates a scan job, and while it doesn't delete or move money, it does execute an external process.
