Single tool 'order_inquiry' has a basic schema with one parameter, but critical gaps undermine quality. Description is minimal (34 chars, below 50-char baseline for clarity). Parameter 'order_id' lacks a description entirely, violates pattern:tool-description. No output schema documented. No error handling guidance. Tool is READ_ONLY but description does not state this. No pagination, no structured response format documented. The implementation returns a hardcoded string, not a real order lookup, suggesting incomplete integration.

• Add a description to the 'order_id' parameter: 'The unique order identifier (e.g., ORD-2024-001234 or numeric ID). Required.'
• Expand tool description to 80 - 150 chars: 'Retrieve the current status and estimated delivery date for a customer order. Returns status (pending, dispatched, delivered), tracking info, and estimated arrival. Call this when a user asks about their order.'
• Document the output schema: { order_id: string, status: enum(pending|dispatched|delivered|cancelled), estimated_delivery: ISO8601 date, tracking_url?: string }
• Add error handling: Return structured errors like { error: 'order_not_found', message: 'Order ORD-123 not found. Try search_orders() with a partial order number or email.' }
• Rename tool to 'get_order_status' to match verb_noun convention and clarify that it retrieves status, not creates or modifies orders.
