8 tools with consistent naming (verb_noun pattern) and descriptions present. All tools have input schemas with typed parameters and descriptions. However, output schemas are completely undocumented, LLMs cannot plan downstream calls or extract structured data. Parameter descriptions lack constraints (enums, ranges, formats). No error handling guidance. Security concern: verify_customer_pin exposes sensitive authentication flow without confirmation pattern. Missing idempotency hints for create_order.

• Document output schema for every tool. Example: 'Returns: {products: [{sku, name, category, price_usd, in_stock}], total_count, next_cursor}'. This enables LLM planning and eliminates discovery calls.
• Convert free-form string parameters to enums. Replace 'category' description with enum: ['Monitors', 'Computers', 'Printers', 'Accessories']. Replace 'status' with enum: ['draft', 'submitted', 'approved', 'fulfilled', 'cancelled'].
• Add pagination to list_products and list_orders: include limit (default 20, max 100), offset/cursor, and total_count in response. Document in descriptions: 'Returns max 20 results per page. Use offset to fetch additional pages.'
• Wrap create_order in a confirmation pattern. Add a dry_run parameter or require explicit user confirmation before executing. Document: 'This operation is irreversible. Verify customer identity and order details before calling.'
• Add idempotency guidance to create_order description: 'Idempotent: calling twice with same customer_id and items returns same order_id. Safe to retry on network failure.' Include idempotentHint annotation in tool metadata.
