AI agents call get_spread_orderbook to retrieve information from Bybit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves market data (orderbook information) with no side effects. It does not create orders, execute trades, delete data, or trigger financial transactions. While it operates on a financial exchange, the retrieval of public or account-specific orderbook data is a Read operation. The low severity reflects that misuse would only expose data, not cause financial loss or irreversible changes.
From the tool's definition 'Get spread trading orderbook' retrieves orderbook data for spread trading without modifying or executing any trades. The verb 'Get' and the read-only nature of retrieving market data indicate a query operation.
