get_city

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

Discloses ethical renaming behavior (ETHICS-009) and lists returned fields. With no annotations, description carries the burden, and it does so adequately by explaining the output structure and special behavior.

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?

Two sentences, each earning its place: first sentence details output fields, second gives usage context. Slightly long first sentence but still concise overall.

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 no output schema and no annotations, the description provides a good overview of the return structure and usage context. Missing error handling but adequate for a simple lookup tool.

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 has 0% coverage, and the description does not explain the city_id parameter beyond what the schema provides (integer, minimum 1). The description focuses on output rather than input semantics.

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 details of a historical city, listing specific fields like name, linguistic variants, coordinates, etc., and explicitly says to use after search_cities, distinguishing it from sibling tools.

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?

Explicitly says 'Usa dopo search_cities per approfondire' (use after search_cities for details), providing clear when-to-use context. No when-not-to guidance, but the context is sufficient for selection.

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