Critical issues: 4 of 8 tools are exact duplicates (greeting, add appear twice; get_alerts, get_forecast appear twice), indicating broken tool registration or multiple conflicting server instances. The 4 unique tools have minimal descriptions (10-50 chars, well below the 194-char baseline). Parameter 'b' in add() has null description. No output schemas documented. No error handling guidance. Tool definitions are scattered across multiple files (server.py, weather.py, greeting.py) with inconsistent registration patterns. FastMCP decorators visible but schemas are inferred from Python type hints rather than explicitly declared.

• Deduplicate tool registration: consolidate greeting, add, get_alerts, get_forecast into a single server instance. Remove duplicate definitions from greeting.py and sse/add/server.py.
• Expand tool descriptions to 100-200 chars. Example for get_alerts: 'Fetch active weather alerts for a US state from the National Weather Service. Returns event type, severity, area, and instructions. Call this to check for warnings before planning outdoor activities.'
• Add explicit output schemas. Document that get_alerts and get_forecast return plain text summaries, or refactor to return structured JSON with fields like {alerts: [{event, severity, area}]} and {forecast: [{period, temperature, windSpeed, description}]}.
• Add parameter descriptions for all fields. For add(), change parameter 'b' description from null to 'The second number to add'. For get_alerts, clarify that state must be a 2-letter code (CA, NY, TX, etc.).
• Implement error handling with recovery guidance. When NWS API fails, return: 'Unable to fetch alerts for state {state}. Verify the state code is valid (2 letters, e.g. CA). If the issue persists, try again in 30 seconds.' Include error classification (retryable vs user-fixable).
