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

With no annotations, the description carries the full behavioral-disclosure burden. It mentions Open-Meteo and coordinate output, but it omits network expectations, error behavior, and how input data is interpreted, leaving significant behavioral ambiguity.

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 sentence is concise and avoids redundant phrasing. Its brevity is partially a weakness given the tool's complexity, but no word in the sentence is wasted.

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 9 optional parameters, no output schema, and no annotations, this single-sentence description is insufficient. It fails to tell the agent which parameter identifies the place and what the exact response shape is.

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 input schema already describes all 9 parameters, so the baseline is 3. The description adds no parameter-level meaning and does not specify which parameter supplies the "place," but it does not contradict 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 clearly states that the tool resolves a place to latitude/longitude via Open-Meteo, which distinguishes it from weather or timezone sibling tools. It lacks an explicit verb and does not map "place" to a specific parameter, but the core purpose is recognizable.

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?

Usage is implied: an agent would use this when needing coordinates for a place. However, there is no explicit when-to-use, when-not-to-use, or alternative tool guidance, so it is not fully actionable.

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