This tool retrieves and displays market data (stock gainers rankings) without modifying data, executing code, deleting information, or moving money.

The blast radius of misuse is minimal—an AI might return incorrect or biased analysis, but cannot cause financial loss or system damage.

From the tool's own definition: "Tool name 'getBiggestGainers' and description 'Track the stocks with the largest price increases' and 'Identify the companies' indicate data retrieval only. No write, delete, execute, or financial transaction capability—purely informational market data query."
