Both tools have critical definition gaps. getWeather and judgeIfOdd lack proper descriptions (Chinese text is non-standard; 'null' description for cityName parameter). Input schemas are present but minimal, cityName has no description, num has a description but both lack type validation details. No output schemas documented. No error handling guidance. Tool names are acceptable (verb-noun style) but descriptions fail the 20-character minimum quality bar. This server would not pass production code review.

• Rewrite tool descriptions in English, 50 - 200 characters, following the pattern: 'What it does. When to use it. What it returns.' Example: 'getWeather: Retrieves current temperature for a city. Returns temperature in Celsius and weather condition. Call when user asks about weather.'
• Add full parameter descriptions with type, range, and format. Example: 'cityName (string, 1 - 100 chars): City name (e.g., Beijing, London). Accepts English or local names.'
• Document output schemas. Example: 'Returns {temperature: number (Celsius), condition: string (sunny|cloudy|rainy), city: string}'.
• Add error handling: 'If city not found, return error: "City not found. Try a major city name (Beijing, Shanghai, etc.)"'.
• Move tool definitions from src/test/java to src/main/java and create proper service classes with @Tool annotations.
