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

The description does not disclose side effects, safety, rate limits, or output behavior. With no annotations, the description carries the full burden and fails to address these aspects.

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 a single concise phrase that is front-loaded with the core purpose. It contains no unnecessary words.

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?

With nine parameters and no output schema, the description is far too sparse to fully guide invocation. It omits which parameter to use, expected output format, and error behavior.

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 descriptions cover all parameters, so the baseline is 3. The tool description does not add meaningful parameter semantics beyond vaguely implying a place-related input.

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 clearly indicates that the tool returns latitude and longitude for a place, and the mention of Open-Meteo distinguishes it from weather, URL, and timezone siblings. However, it does not explicitly say 'get' or clarify which input parameter identifies the place.

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?

There is no guidance on when to use this tool versus alternatives such as weather-hint or normalize-url. No use cases or conditions are provided.

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