## Why getWilliams is rated Low

Williams %R is a technical analysis indicator that reads historical price data and computes a momentum oscillator. It retrieves and processes existing financial data without modifying, deleting, or executing any irreversible operations. The result is informational analysis to support trading decisions, not an actual financial transaction. This is a pure read operation with minimal risk.

From the tool's own definition: "Tool name 'getWilliams' and description 'Calculate the Williams %R for a stock' and 'analyze overbought/oversold conditions' indicate data retrieval and technical analysis calculation. No write, execute, destructive, or financial operations are performed."
