What metaharness_oia_audit does on Hamza Agent Hub 252
AI agents use metaharness_oia_audit to create or update resources in Hamza Agent Hub 252, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hamza Agent Hub 252 environment.
Why metaharness_oia_audit is rated Medium
The tool aggregates security/audit artifacts (manifest, threat model, MCP scan) and persists a timestamped record, which is a Write operation — creating a new stored audit record. It does not appear to delete data or execute arbitrary code, but the truncated description reduces confidence slightly. Severity is medium because misuse could produce false or misleading audit records in an enterprise security context.
