Server provides 2 weather tools with basic input schemas and descriptions. Both tools follow verb_noun naming convention (get_alerts, get_forecast) which is good. However, definitions lack critical details: no output schemas documented, no error handling guidance, parameter descriptions are minimal, no bounds on numeric inputs, and no enum constraints. Descriptions are present but terse (13-15 chars for parameters). Tools are READ_ONLY which is correct, but the server lacks structured output documentation that LLMs need for downstream reasoning.

• Document output schema for get_alerts: return structured JSON with fields: alerts (array of {event, area, severity, description, instruction}), alert_count, state, timestamp. Avoid free-form string concatenation.
• Document output schema for get_forecast: return structured JSON with fields: periods (array of {name, temperature, temperature_unit, wind_speed, wind_direction, detailed_forecast}), location, generated_time, valid_times. Cap at 5 periods but document this in the description.
• Expand parameter descriptions. For 'state': 'Two-letter US state code (CA, NY, TX, etc.). Must be uppercase. Used to query active weather alerts for that state.' For latitude/longitude: 'Latitude (-90.0 to 90.0, negative = south). Longitude (-180.0 to 180.0, negative = west). Example: 37.7749, -122.4194 for San Francisco.'
• Add error recovery guidance. If get_alerts returns 'Unable to fetch alerts': 'This usually means the NWS API is temporarily unavailable or the state code is invalid. Verify the state code is valid (e.g. CA, NY) and retry after a few seconds. If the state code is wrong, ask the user to provide a valid two-letter code.'
• Add error recovery guidance. If get_forecast returns 'Unable to fetch forecast data': 'This usually means the coordinates are outside the US National Weather Service coverage area or the API is unavailable. Verify coordinates are within the contiguous US. Retry after a few seconds if the API is temporarily down.'
• Expand tool descriptions to explain WHEN to use each. get_alerts: 'Retrieves current active weather alerts for a US state. Use this when the user asks about warnings, watches, or urgent weather threats in a specific state.' get_forecast: 'Retrieves the 5-day weather forecast for specific coordinates. Use this when the user asks about upcoming weather conditions at a specific location.'
