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

The description discloses no behavioral aspects such as read-only nature, side effects, permissions, or potential failures. Since no annotations are provided, the description alone carries no transparency about these traits.

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, clear sentence with no unnecessary words. It is well-structured and immediately understandable.

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?

The description is incomplete for practical use: it does not indicate which of the 9 optional parameters contains the place name, nor does it mention output format or any example. This leaves significant ambiguity for an agent trying to invoke the tool correctly.

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 schema description covers 100% of the parameters, so the baseline is 3. The tool description adds no additional meaning about which parameter to use for the place or how the parameters relate to the geocoding function.

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 the tool returns latitude and longitude for a place via Open-Meteo, which gives a specific verb and resource. However, it does not specify which parameter should be used for the place, and it does not differentiate from similar 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 versus alternative tools, such as weather-hint or search-query-len. No conditions or scenarios are mentioned.

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