AI agents call sentrul_compliance_scan to retrieve information from Sentrul without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs compliance scanning—analyzing input text to detect sensitive data patterns. It retrieves or identifies information (Read category) rather than creating, modifying, executing commands, or deleting data. The severity is low because misuse would at worst cause false positives or redundant scans, with no destructive or financial consequences.
From the tool's definition The tool 'scans text for common compliance patterns' without modification capabilities. The description indicates pattern detection and analysis (PII, PCI, HIPAA, GDPR data identification) which are read-only operations that retrieve or query information…
