AI agents call get_trade_history to retrieve information from Kiwoom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves historical trade data and profit/loss information from the user's own account. It does not modify, delete, or execute any transactions. While it accesses financial account data, the tool itself does not move money, commit obligations, or trigger trades—it is purely informational.
From the tool's definition Tool description states it 'retrieves/queries' (조회합니다) trade history including buy/sell records and profit/loss data from the past 2 months. The verb '조회' (inquire/lookup) indicates a read operation with no side effects.
