Two tools with basic but incomplete definitions. Both tools have adequate names and functional descriptions, but lack critical structured output documentation, parameter descriptions are minimal, and no error handling guidance is present. Tool definitions are directly visible in the source code (weather.py), so no inference penalty applies. Both tools return unstructured string responses rather than typed objects, which is a significant gap for agent composition. Parameter 'city' is a free-form string with no format constraints, enum values, or validation examples. No output schemas are documented, agents cannot predict or parse the response structure. Error messages are basic strings with no recovery guidance.

• Define output schemas as typed JSON objects. For get_alerts: {alerts: string[], safe: boolean, temp_c: number, wind_kmph: number}. For get_forecast: {city: string, current: {temp_c: number, description: string, humidity: number}, forecast_days: [{date: string, min_temp: number, max_temp: number, summary: string}]}. This enables agents to extract specific fields and chain outputs.
• Add parameter constraints. Define city as an enum of ~30 major Indian cities (Delhi, Mumbai, Bengaluru, etc.) or document the expected format with a regex pattern and examples. Alternatively, add a 'list_supported_cities' discovery tool.
• Implement structured error responses. Return JSON objects like {success: false, error_type: 'invalid_city', message: 'Delhi not in supported list', suggestion: 'Did you mean: New Delhi?'} instead of plain strings. This lets LLMs parse errors programmatically.
• Add per-error recovery hints. For invalid city errors, suggest calling a city search tool first. For network timeouts, advise retrying. For API rate limits, recommend exponential backoff.
• Expand tool descriptions with selection context. E.g., 'Use get_alerts for immediate safety warnings (heatwaves, storms). Use get_forecast for trip planning and activity scheduling.' Add a note that alerts check current conditions while forecast covers the next 2 days.
• Add a 'list_supported_cities' or 'search_cities' tool to help agents discover valid city names before calling weather tools. This prevents hallucinated city names.
