The server implements 2 weather tools with basic name clarity and functional parameter schemas. Both tools have appropriate descriptions and input parameters with types and descriptions. However, critical gaps exist: no output schemas are documented, no error handling guidance is provided, no parameter constraints (enums, ranges) are enforced or documented, and no idempotency or destructive-operation guidance is present. Tool names follow verb_noun convention (GetAlerts, GetForecast) but are PascalCase rather than snake_case (get_alerts, get_forecast), which is inconsistent with LLM-friendly naming conventions. Parameter descriptions are minimal (20-40 chars) and lack constraint details (e.g., latitude/longitude ranges, state code format validation). The tools return string responses rather than structured JSON, forcing LLMs to parse text. Overall, the definitions are functional but lack the completeness expected of production-grade tools.

• Document and return structured output schemas: GetAlerts should return an array of {event: string, area: string, severity: string, description: string, instruction: string}, not a formatted string. GetForecast should return an array of {name: string, temperature: number, wind_speed: string, wind_direction: string, detailed_forecast: string}.
• Add parameter constraint documentation: 'state' description should specify '2-letter US state abbreviation (e.g., NY, CA). For invalid codes, returns 'No active alerts for this state.''. For latitude/longitude, specify 'Decimal degrees, range: latitude [-90, 90], longitude [-180, 180]. Required for valid forecast.'
• Provide error recovery guidance: 'If the state code is invalid or no data is available, the tool returns a default message. For persistent failures, the weather.gov API may be temporarily unavailable, wait and retry.'
• Rename tools to snake_case: GetAlerts → get_alerts, GetForecast → get_forecast, following LLM-standard naming conventions.
• Enhance descriptions with read-only and idempotency signals: Both tool descriptions should explicitly state 'This tool is read-only and idempotent, it is safe to retry on failure.' to guide agent behavior.
• Add pagination and result limits where applicable: Document that GetAlerts may return multiple alerts; consider capping result count in description (e.g., 'Returns up to 20 active alerts for the state').
• Validate inputs early and return actionable errors: Catch invalid state codes and malformed lat/long in the tool handler, returning clear messages like 'Invalid state: XX. State must be a 2-letter abbreviation (NY, CA, etc.)' instead of generic exceptions.
