RISK

Why getStockPriceChange is rated Low

getStockPriceChange is a read-only query tool that retrieves historical and current market data. It has no side effects, creates no data, executes no code, and performs no destructive operations. While financial market data can inform trading decisions, the tool itself only retrieves quotes and statistics—it does not execute trades, move money, or commit financial obligations.

From the tool's definition Tool name and description indicate retrieval of stock price change data: 'Track stock price fluctuations in real-time' and 'Monitor percentage and value changes'. The verb 'Track' and 'Monitor' indicate passive observation of data without modification.
