## Why getHistoricalIndexFullChart is rated Low

This tool retrieves financial market data without side effects. It accesses historical stock index pricing information for analysis purposes only. No write operations, code execution, irreversible actions, or financial transactions are performed. The blast radius of misuse is minimal - an agent requesting incorrect index data causes no harm beyond potentially flawed analysis.

From the tool's own definition: "Tool provides 'historical end-of-day prices' and 'comprehensive information, including open, high, low, close prices, volume' - purely data retrieval with no modification, creation, deletion, or execution capabilities."
