Server has critical structural issues. Tool definitions exist but lack rigor: descriptions are present but minimal (10-30 chars), parameter descriptions are sparse or missing, and output schemas are entirely undocumented. Duplicate tool registrations (get_alerts and get_forecast appear twice) suggest incomplete or broken tool discovery. No input validation, error guidance, or structured output documented. Parameter types are present in schema but descriptions are absent for most params. This is a D-grade server with major gaps in definition quality.

• Remove duplicate tool registrations. Audit server.py and client-sse.py to ensure each tool is registered exactly once with consistent schema.
• Document output schemas for all tools. Define structured return types (e.g. {alerts: [{event, area, severity, description}], count: int}) instead of plain strings.
• Add parameter descriptions for latitude and longitude in get_forecast. Specify valid ranges (e.g. latitude -90 to 90, longitude -180 to 180) and format expectations.
• Implement error classification and recovery guidance. Replace 'Unable to fetch alerts' with 'Failed to fetch alerts from NWS API. Verify state code is valid (e.g. CA, NY) or try again in 30 seconds.'
• Rename echo_resource to clarify intent. If it echoes a message as a resource, use 'create_echo_resource'. If it retrieves, use 'get_echo_resource'.
