## Why stock_return is rated Low

This tool performs a computational analysis of historical stock performance metrics (price change and dividend data). It reads input parameters and returns calculated results with no side effects, no data modification, no transactions, and no financial movements.

From the tool's own definition: "Tool name 'stock_return' with description 'Calculate total stock return including price change and dividends' indicates a pure calculation/query operation that retrieves or processes financial data without executing transactions, modifying records, or…"
