AI agents call get_org_billing_codes to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves billing code reference data for informational purposes. Reading billing codes does not execute financial transactions, modify data, or trigger external operations. While billing data is sensitive, the retrieval itself is read-only with minimal blast radius.
From the tool's definition Tool name and description both indicate a retrieval operation: 'Get all available billing codes' — no creation, modification, deletion, or financial transaction occurs. This is a query-only action.
