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

No annotations are provided, and the description does not disclose whether the tool makes an external network call to Open-Meteo, whether it is read-only, or what side effects might occur. The parameter descriptions mention 'discarded after' and 'no disk access', but this is not integrated into the tool description.

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 that is easy to read and front-loads the core purpose. It loses some points for omitting essential usage details, but there is no verbosity or structural clutter.

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?

Given the tool has nine parameters, no required fields, and no output schema, the description is incomplete. It does not explain which parameter to use, what the output format will be, or how to handle errors. The description is too minimal for an agent to reliably invoke the tool.

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?

Although every parameter has a schema description, the tool description does not clarify which parameter is relevant for obtaining latitude and longitude. The schema descriptions themselves are terse and many seem unrelated to geolocation, so the description adds little semantic value beyond the schema and may confuse an agent.

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 that the tool returns latitude and longitude for a place via Open-Meteo, which gives a general purpose. However, the schema lists nine unrelated parameters (ref, url, feed, host, json, path, zone, query) with no indication of which one identifies the 'place', making the actual purpose ambiguous and not clearly distinguished from sibling tools like weather-hint.

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 no guidance on when to use this tool instead of alternatives such as weather-hint or timezone. It does not specify the input to provide, nor does it mention any conditions or examples.

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