This server defines a single tool 'get_weather' with minimal structure. The tool has a basic description (11 words, within range) but critical gaps in parameter documentation, error handling, output schema documentation, and lacks any validation or recovery guidance. The implementation is trivial (returns a hard-coded string), which is acceptable for a demo but the definitions lack production-grade rigor. Parameter 'city' has no description despite being the only input, this violates the critical check that every parameter needs a description explaining what it controls. No output schema is documented. Error handling is absent, no recovery guidance, no input validation, no error classification. The tool does not demonstrate awareness of agent-interaction patterns.

• Add a non-empty description to the 'city' parameter: 'The name of the city (e.g. New York, London, Tokyo). City names are case-insensitive.'
• Document the output schema. Example: 'Returns a string with the current weather summary for the given city (e.g. "The weather in London is sunny and 72°F").' or better yet, return a structured object: {city: string, temperature: number, condition: string, unit: string}.
• Add error handling guidance: 'If the city is not found, the API returns an error. Try searching for nearby cities or verify the spelling.' Return specific error messages like 'City "Ney York" not found. Did you mean: New York, New York Mills?' instead of a generic error.
• Add input validation: constrain city name length (e.g. 1 - 100 characters), reject empty strings with a clear message.
• Consider returning structured JSON (city, temperature, condition, humidity, wind_speed) instead of a flat string. Structured responses let LLMs extract and reason about individual fields without parsing prose.
• Add a 'units' parameter (enum: celsius|fahrenheit|kelvin) to make the tool more flexible and demonstrate constrained input handling.
• Document any prerequisites (e.g. 'Requires an active internet connection'; 'Limited to [N] calls per minute'). This helps agents plan resource usage.
