create_country

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

The description adds no behavioral information beyond what the annotations already convey. Annotations indicate readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the agent knows it is a non-read, non-destructive write operation. But the description does not disclose any additional behavioral traits such as duplicate handling, required permissions, or side effects.

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 extremely short, but this is under-specification rather than effective conciseness. It conveys no useful information beyond the tool name, so the brevity does not serve a purpose.

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 output schema, no parameter descriptions, and a minimal description, the tool is severely under-documented. An agent cannot determine what data is required, what the response will be, or how to use the tool correctly in context.

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 has zero description coverage for its three parameters (name, name_short, iso3166_alpha2), and the description 'Create country' provides no explanation of what these parameters mean, their format, or requirements. The description fails to compensate for the lack of schema documentation.

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 'Create country' clearly identifies the action (create) and the resource (country). It distinguishes from sibling tools like delete_country, get_country, and list_countries through the verb. However, it lacks any additional context about what a country is or specific scope.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites, when creating a country is appropriate, or reference related tools like update_country or search_countries. The usage context is entirely implied.

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