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

No annotations are provided, and the description does not disclose any side effects, error handling, or data persistence. The parameter descriptions (e.g., 'discarded after the call') are inconsistent with the tool's stated purpose, further reducing transparency.

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 concise sentence, which is appropriate in length, but it lacks structure such as examples, parameter hints, or output expectations. It reads as a minimal stub rather than a well-formed specification.

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 complexity of nine parameters and no output schema, the description is severely incomplete. It does not state which input is required, how the place is identified, or what the output format will be, leaving the agent unable to invoke the tool 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?

The description adds no clarification on which of the nine parameters supplies the place name. The schema descriptions themselves are misleading (e.g., 'city' for a weather hint, 'query' for a length check), so the description fails to map parameters to functional inputs.

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, distinguishing it from siblings like weather-hint and timezone. However, it does not specify which parameter actually denotes the place, leaving some ambiguity.

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 offers no guidance on when to use this tool over alternatives (e.g., weather-hint, timezone) or any conditions for selection. No context about typical use cases is provided.

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