## Why consultar_inss_vigente is rated Low

This tool queries and returns static reference data (INSS contribution tables, tax brackets, rates, ceilings, dependent deductions). It performs no calculations on user data, creates no records, executes no external operations, and has no destructive side effects. The description explicitly notes it is 'útil quando o LLM precisa explicar' (useful when the LLM needs to explain)—a read-only informational function.

From the tool's own definition: "Tool name 'consultar_inss_vigente' and description 'Retorna a tabela INSS vigente' (returns current table). No arguments that modify data; purely retrieves and displays regulatory tax tables and rates."
