Missing required parameter: symbol
Error message
Missing required parameter: symbol
What it means
Required-parameter guard in the stock-price tool's execute: `symbol` is missing, non-string, or trims to empty (the .filter(!is_empty) chain means blank strings also land here). Fires before any market-data request; the caller must supply a ticker such as AAPL or SPY.
