The server defines 2 tools with basic structure, but exhibits significant quality gaps. Tool names follow verb-noun conventions (get-alerts, get-forecast), which is positive. However, descriptions are minimal (14-29 chars, well below the 50-200 char baseline for A+ tools), parameter descriptions are sparse or missing, and there is no documented output schema. Input schemas use Zod validation and include type constraints (lat/lon ranges, state length), which is a bright spot, but the lack of comprehensive parameter guidance and output documentation limits LLM ability to compose these tools effectively. Error handling is present but generic ('Failed to retrieve data'); it does not guide the agent toward recovery strategies. The server lacks tool annotations (readOnlyHint, idempotentHint), which would clarify intent. Overall, this is a functional but below-median implementation.

• Expand tool descriptions to 100 - 150 characters. Example: 'get-alerts: Retrieve active weather alerts for a US state (2-letter code). Returns event type, severity, affected area, and headline. Useful for checking if dangerous conditions are in effect. Only supports US locations.'
• Document the output schema explicitly. Define that get-alerts returns a list of alerts with fields: event (string), areaDesc (string), severity (string), status (string), headline (string). Define that get-forecast returns an array of periods, each with: name, temperature, temperatureUnit, windSpeed, windDirection, shortForecast.
• Return structured JSON objects instead of plain-text blocks. This allows LLMs to extract and reason about individual alerts or forecast periods without string parsing.
• Enhance error messages with actionable guidance. E.g., 'Invalid state code: got "CA2". State codes must be exactly 2 uppercase letters (e.g., CA, NY, TX). Try again with a valid code or call list_us_states() for valid options.'
• Add tool annotations to the server.tool() calls. Both tools should declare readOnlyHint: true to signal they are safe to retry and do not modify state.
• Expand parameter descriptions to include constraints and examples. E.g., state: 'Two-letter US state abbreviation (e.g., CA for California, NY for New York). Must be uppercase. Invalid codes will return a 404 error.'
• Add pagination support to get-alerts. Accept optional 'limit' (default 20, max 100) and 'offset' parameters, and return total_alerts count in the response so the LLM can fetch more if needed.
