RISK

Why sweep_agent is rated Critical

Even though it moves funds 'back to operator,' it is a financial transfer operation that could be misused to drain an agent's wallet. Requires an operator key, indicating elevated privilege. Misuse could result in loss of funds or unauthorized fund movements, warranting critical severity.
