Four tools with basic schemas and minimal descriptions. All tools have input schemas with proper types and required flags, but descriptions are generic (10-50 chars) and lack context for LLM selection. No output schemas documented. Parameters lack enums, ranges, or format constraints. No error handling guidance. search_cars_tool and recommend_cars_tool are functionally identical (same params, similar intent), violates single-responsibility principle. get_car_details_tool returns hardcoded localhost URLs, a security/portability issue. No pagination support despite returning lists.

• Merge search_cars_tool and recommend_cars_tool into a single search_cars tool, or document the semantic difference (e.g., 'search' is keyword-based, 'recommend' applies ML ranking). Avoid LLM confusion.
• Expand all tool descriptions to 100-200 characters. Include: what the tool does, when to use it vs similar tools, and what fields the response contains. Example: 'Search cars by make, model, price, location, and condition. Returns car ID, price, mileage, and contact info. Use this for keyword searches; call get_car_details for full specs and images.'
• Document output schemas for all tools. Specify that search_cars_tool and recommend_cars_tool return arrays of {id, make, model, year, price, mileage, fuel_type, transmission, city, contact_number, description, seller_id}. Specify that get_car_details_tool returns a single car object with an 'images' array of {id, image_url}.
• Add enums for fuel_type (e.g., 'petrol', 'diesel', 'hybrid', 'electric') and transmission (e.g., 'manual', 'automatic'). Add min/max constraints to numeric parameters: min_price ≥ 0, max_price ≤ 10000000, min_year ≥ 1900, max_year ≤ current_year, min_mileage ≥ 0, max_mileage ≤ 1000000.
• Fix hardcoded localhost URL in get_car_details_tool. Use an environment variable (e.g., BASE_URL from config) or construct the URL from the request context. Return relative paths if possible, or document the expected base URL in the tool description.
