Why Good Descriptions Matter
The LLM uses your descriptions to decide:
- WHEN to use a tool
- WHAT arguments to pass
- HOW to interpret results
Bad description: "Gets order info"
Good description: "Look up the current shipping status, tracking number, and estimated delivery date for a customer order. Use this when a customer asks about their order status."
