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

No annotations are present, so the description must carry the full behavioral burden. It only mentions that the call goes through Open-Meteo and does not disclose that most parameters are discarded, whether the operation is read-only, or what happens on a failed lookup.

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 single sentence is front-loaded and contains no filler, making it easy to parse. It is arguably too terse for a seven-parameter tool, but the conciseness itself is not the main weakness.

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 confusing seven-parameter input, the description is not self-sufficient. It omits which parameter supplies the place, what the return payload looks like beyond lat/lon, and how the discarded parameters should be treated, leaving too much to inference.

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 already documents all parameters, so the baseline is 3. The description's word 'place' weakly points toward 'city', but it does not explicitly map the purpose to the correct parameter or clarify how the other shape-check/discarded parameters relate to the tool.

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 action: it resolves a place to latitude and longitude, which is distinct from weather-hint and other siblings. However, it is phrased as a noun phrase rather than a clear directive and does not say which input parameter represents the place.

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 geo-hint instead of weather-hint, timezone, or other sibling tools. The description also does not tell the agent that among the seven schema parameters, only 'city' is the likely place input and that the others are irrelevant or discarded.

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