## Why flash_quote is rated Low

flash_quote retrieves pricing information and quotes across liquidity sources. It performs no execution, modification, or financial transaction. The absence of execution capability and wallet requirement confirms this is a read-only operation that queries market data for informational purposes.

From the tool's own definition: "Tool description explicitly states it prices a trade 'without executing' and 'Does not require a wallet', indicating data retrieval only with no side effects."

Risk signals: High parameter count (19 properties)
