What get_invoice_stats does on FavCRM
AI agents call get_invoice_stats to retrieve information from FavCRM without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_invoice_stats is rated Low
This tool retrieves and queries financial data without creating, modifying, or deleting records, and does not move money or commit financial obligations. It is purely informational, used for reporting and analytics in the weekly snapshot. While the data concerns invoices (a financial domain), the tool itself performs no financial transactions or irreversible actions, making it a Read operation with low severity.
From the tool's definition Tool name and description indicate retrieval of statistics: 'Outstanding totals, overdue counts, and revenue this period.' The verb 'get' and the query-like nature (fetching aggregated invoice data) with no modification operations confirm read-only access.
