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

With no annotations, the description carries the full behavioral burden. It names the provider and return concept, but it does not disclose the output shape, expected input mapping, failure behavior, or side effects, and it never explains how 'a place' maps to the ten schema parameters.

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 efficient sentence with no filler or repetition. However, it is shorter than necessary for a 10-parameter tool and omits the semantic link between the input parameters and the promised output.

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?

This is drastically underspecified for a tool with 10 optional parameters and no output schema. An agent cannot confidently determine which input to provide, what the coordinate response looks like, or what happens on invalid input.

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 coverage is 100% and every parameter already has an individual description, so the baseline is 3. The description adds no parameter-level meaning and fails to clarify which optional field is the 'place' that produces the latitude and longitude.

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 resolves a place to latitude and longitude and names Open-Meteo as the provider, which is a concrete and specific function. It is distinct enough from siblings like weather-hint, though it lacks an explicit verb such as 'gets' or 'returns'.

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 use geo-hint instead of any sibling tool, such as weather-hint, timezone, or iana-zones. An agent must infer the intended use from the name and provider alone.

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