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

With no annotations available, the description carries the full burden of behavioral disclosure. It only mentions Open-Meteo and does not explain that it makes an external network call, how errors or unknown places are handled, whether the operation is safe/read-only, or what output shape to expect.

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 sentence with no filler. It communicates the core function in eight words and earns its place.

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?

There is no output schema and no annotations, and the input schema is unusually broad with seven unrelated-looking fields. A one-line description does not tell an agent which parameter supplies the place or what the response looks like, so it is not fully actionable without additional inference.

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?

The input schema already provides descriptions for all parameters, so the baseline is 3. The description does not add parameter-level meaning, and it never maps 'a place' to the `city` parameter, but it does not contradict the schema either.

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 states that the tool resolves a place to latitude and longitude using Open-Meteo. It is specific enough to distinguish this from siblings like weather-hint, though it lacks an explicit verb such as 'get' or 'look up'.

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 implies it should be used when geographic coordinates for a place are needed, but gives no explicit guidance on when to prefer it over alternatives or any exclusions. It provides clear context but no comparison with sibling tools.

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