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

No annotations are provided and the description does not disclose side effects, external network usage, error behavior, or data handling. The mention of Open-Meteo implies an external call, but no behavioral details are given.

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 focused sentence with no filler, and the core output is front-loaded. It is appropriately concise.

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 large optional parameter set and no output schema, the description omits essential context such as expected input mapping, return format, and failure modes. It is far from complete enough for an agent to invoke reliably.

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 descriptions exist for all parameters, but many are generic and unrelated (e.g., git ref, RSS feed, JSON text), and the tool description does not clarify which one is the 'place'. This adds confusion rather than useful meaning beyond the schema.

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 returns latitude and longitude for a place via Open-Meteo, giving a clear high-level purpose. However, it does not specify which of the nine optional parameters identifies the place, so the purpose is not actionable from the description alone.

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 choose this tool over other sibling tools, nor any mention of prerequisites or context. The description simply states what it does without explaining usage conditions.

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