## Why domain_shield is rated Low

domain_shield is a diagnostic tool that queries multiple data sources (VirusTotal, DNS records, SSL certificates) and returns security assessment scores and recommendations. It does not modify systems, execute code, delete data, or move funds. The primary risk is information disclosure if sensitive domain details are exposed, but this is minimal since domain security information is typically semi-public.

From the tool's own definition: "Tool performs scanning and assessment activities: 'Domain security scan with VirusTotal malware detection', 'SPF, DKIM, DMARC, SSL, MX, DNSSEC, domain info."

## Use case

AI agents call domain_shield to retrieve information from Alderpost without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
