This tool retrieves and queries data (price levels from Pine Script indicators) without modifying, deleting, or executing any external operations. It is purely informational and carries no blast radius if misused by an AI agent, as it cannot alter state or trigger financial transactions. The severity is low because the data returned is already visible on the chart and poses no security or operational risk.
