## Why switch_cross_isolated_margin is rated High

This tool changes the margin mode for trading positions, which is an operational change that affects how collateral is allocated and liquidation risk is managed. It doesn't directly move money or delete data, but it triggers a significant account-level configuration change that can affect the entire account balance used as collateral.

From the tool's own definition: "Switch between cross margin (uses entire account balance as collateral) and isolated margin (uses only position margin). Cross margin has lower liquidation risk but affects entire account."
