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

With no annotations provided, the description carries the full burden of disclosing behavior. It mentions the Open-Meteo source but does not state whether the tool is read-only, what inputs are required, or what errors/side effects may occur.

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 sentence with no redundant wording, making it appropriately concise for the information it conveys.

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 complex 9-parameter schema and no output schema, the one-line description is not complete enough: it does not specify how to provide the place, what the response shape is, or what happens with the many unrelated parameters.

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 all 9 parameters have schema descriptions, the description does not connect them to the geocoding purpose, and the schema mixes unrelated fields (ref, url, feed, host, json, path, zone) with optional city/query fields. This leaves ambiguity about which parameter actually specifies the place.

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 tool returns latitude and longitude for a place using Open-Meteo, which is a concrete outcome and distinguishes it from weather-specific siblings. However, it does not specify the input parameter or output format, so it is not fully precise.

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?

No guidance is given about when to prefer geo-hint over sibling tools such as weather-hint or timezone, nor does it mention any exclusions or alternatives. The intended use is only implied by the name and one-line purpose.

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