REM Pricing Tool with Knowledge Base and Website Integration
REM ============================================================================
REM This example demonstrates:
REM 1. Product pricing lookup from CSV database
REM 2. Integration with product brochures KB
REM 3. Dynamic website content indexing

PARAM product AS string LIKE "fax" DESCRIPTION "Required name of the product you want to inquire about."

REM Tool description
DESCRIPTION "Whenever someone asks for a price, call this tool and return the price of the specified product name. Also provides access to product documentation and specifications."
