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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the external dependency on Open-Meteo and the output (latitude/longitude), but it does not disclose network dependency, error behavior, data retention, or side effects. The schema's 'discarded' notes add some transparency, but the description itself is thin.

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, front-loaded sentence with no wasted words. It is concise and readable, though the brevity comes at the cost of omitting important usage and parameter context.

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 nine optional parameters, no output schema, no annotations, and many sibling tools, this description is inadequate for reliable invocation. It does not state which parameter to pass, what the return format looks like, or how to distinguish this tool from weather-hint and other location-related tools.

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 description coverage is 100%, so every parameter already has an explanation and the baseline is 3. The tool description adds little parameter-level meaning and does not explicitly map 'a place' to any specific parameter, though 'city' is an obvious candidate from the schema.

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 returns latitude and longitude for a place and identifies the data source (Open-Meteo). It is not a tautology and is more specific than merely restating the tool name. However, it does not differentiate the tool from siblings like weather-hint that may also relate to places or Open-Meteo.

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 about when to use this tool versus alternatives, no prerequisites mentioned, and no mention of which parameter is the relevant 'place' input. An agent must infer usage from the schema alone, which contains nine unrelated-looking optional parameters.

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