AI agents call show_audit_log to retrieve information from Ogham without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays audit log data with interactive filtering/sorting capabilities. It performs read-only operations on existing audit records. No side effects, data creation, deletion, or financial operations are possible. The moderate severity reflects that audit logs may contain sensitive historical information, but the tool itself only queries and displays existing data.
From the tool's definition Tool name 'show_audit_log' and description 'Interactive audit log table with sorting and search' indicate data retrieval and query operations with no modification or destructive capability.
