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

No annotations are provided, so the description carries the full behavioral burden. It mentions that the data comes via Open-Meteo, implying an external call, but it does not disclose whether any input is persisted, what happens on failure, rate-limit implications, or what the response format will be. The schema notes that some fields are 'discarded', but the description itself adds little behavioral context.

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 filler. It is concise and communicates the essential purpose quickly, though it is quite terse relative to the 9-parameter schema.

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 no annotations, no output schema, and a 9-parameter schema, the description is too sparse to fully support invocation. It names the return concept—latitude and longitude—but does not specify the output format, which parameter identifies the place, or how the many unrelated-looking parameters fit in. The description is not complete enough for an agent to confidently parameterize the call.

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 the baseline is 3; the schema already documents each parameter. The description adds the useful geocoding purpose via Open-Meteo, but it does not clarify which of the 9 parameters should be used to supply the 'place' or how they relate to the returned coordinates.

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 the core output clearly: latitude and longitude for a place, using Open-Meteo as the provider. It does not explicitly name an input parameter like 'city', but 'place' maps reasonably to the schema's city field and distinguishes this 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 gives no guidance on when to use this tool versus alternatives such as weather-hint, timezone, or iana-zones. There are no conditions, exclusions, or explicit alternative routing, leaving the agent to infer the appropriate context from the tool name and description alone.

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