get_current_weather

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

No annotations are provided, so the description bears full responsibility. It only states the tool 'gets' weather, implying a read operation, but fails to disclose potential behaviors such as rate limits, authentication needs, or error handling. Essential transparency is missing.

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?

The description is concise, with two clear lines for purpose and parameters. The args section is structured. However, the purpose could be more tightly integrated with the parameter description to reduce redundancy.

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?

Despite low complexity (single parameter, no nested objects), the description lacks information about the output format (e.g., temperature, conditions) and does not specify any edge cases or behavior when the city is not found. This omission hinders the agent's ability to fully understand the tool's capabilities.

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?

With 0% schema description coverage, the description compensates by explaining the 'city' parameter as '中国城市名称' (Chinese city name) and providing examples. This adds useful meaning beyond the schema, though it does not specify format constraints or acceptable input variations.

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?

The description states '获取指定城市的实时天气' (get real-time weather for specified city), clearly indicating the verb and resource. However, it does not differentiate from the sibling tool 'get_weather_forecast', as 'current' is only implied by the tool name.

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?

The description provides context that the tool is for current weather of a city, but it does not explicitly advise when to use this tool versus 'get_weather_forecast' or 'search_city'. Usage is implied but not explicitly guided.

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