Single tool 'get-alerts' has a clear verb-noun name and basic schema with Zod validation. However, the description is minimal (47 chars), lacks context on when/why to use it, and does not explain the output structure. Parameter description is adequate but generic. No error handling guidance, no output schema documentation, and the tool returns mock data rather than real API integration. The implementation shows basic competence but falls short of production quality, descriptions are too terse, output structure is undocumented, and error paths are not actionable.

• Expand tool description to 100-200 chars: 'Retrieve active weather alerts for a US state. Returns a list of active alerts with event type, severity, and headline. Call this to check for weather warnings before planning outdoor activities. Returns empty if no alerts are active.'
• Document the output schema explicitly: 'Returns an object with fields: alerts (array of {event, area, severity, status, headline}), state (string), timestamp (ISO 8601).'
• Add error handling guidance: 'If the API is unavailable, returns error_code: SERVICE_UNAVAILABLE with retry_after_seconds. If the state code is invalid, returns error_code: INVALID_STATE with a list of valid state codes.'
• Implement real NWS API calls instead of mock data. Replace the hardcoded mockResponse with actual fetch() calls to https://api.weather.gov/alerts?area={state}.
• Update parameter description to: 'Two-letter US state code (e.g., CA, NY). Must be uppercase. Automatically converted to uppercase if provided in lowercase.'
