Single tool 'current_weather' has a verb-noun name (good), but the description is extremely brief (24 chars) and lacks critical context. Input schema is minimal: only 'city' parameter with basic string type, no format constraints, no examples of valid input, no error guidance. No output schema documented. The tool appears to be a thin wrapper around a remote API (dynamicfeed.ai/mcp) with 91 tools, but this example only demonstrates one. No parameter validation rules, no error handling guidance, no idempotency guarantees. The description does not explain when to use this tool, what format the response takes, or what happens on failure (e.g., invalid city name).

• Expand description to 50-150 characters: 'Get current weather conditions (temperature, humidity, wind) for a city. Returns structured JSON. Call this to answer weather questions; use forecast_weather for multi-day predictions.'
• Document output schema explicitly: 'Returns {temperature: number (°C), humidity: number (0-100), wind_speed: number (km/h), condition: string (sunny|cloudy|rainy|snowy), last_updated: ISO8601}'
• Add validation rules to 'city' parameter: 'City name (2-100 chars, letters/spaces/hyphens only). E.g., "New York", "San Francisco". If ambiguous, returns top match; call search_cities() first if unsure.'
• Add error handling guidance: 'If city not found, returns error with available matches. If API timeout, retry after 5 seconds. If coordinates provided instead of name, call reverse_geocode() first.'
• Declare idempotency: 'Idempotent, same city always returns current conditions. Safe to retry on failure.'
