AI agents call school_district to retrieve information from Attom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves public school district information, which is informational data lookup with no capability to modify, delete, or execute operations. It poses minimal risk as a read-only data retrieval operation. The low severity reflects that misuse would only result in unauthorized data access, not resource damage or financial impact.
