get_weather_by_name

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries burden. Mentions return format (Dict with 'data' and '_meta'), lists possible provider values, and notes error handling (MCPError). However, lacks details on API dependencies, data freshness, or any destructive behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is concise with a clear paragraph and structured Args/Returns/Raises section. No redundant content, but could be more structured with bullet points.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers purpose, parameters, return format, and errors. Missing details like timezone, units, or comparison with sibling 'get_weather_by_position'. Adequate for a simple tool but leaves some gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so description compensates. Explains place_name as 'place name (e.g., city/district)' and provider as 'mode, optional all/qweather/open-meteo/wttr'. Adds meaning beyond schema but could elaborate on provider differences.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it retrieves comprehensive weather (current, hourly, daily) by location name. Verb 'get' and resource 'weather' are explicit. Distinct from sibling 'get_weather_by_position' which uses coordinates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternative 'get_weather_by_position' or other siblings. Implicit that it's for place names, but no explicit when-to-use or when-not-to-use instructions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
