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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the SOAP method name, without detailing what the tool does (e.g., read-only operation, data format, potential errors, or rate limits). For a tool with zero annotation coverage, this is insufficient to understand its behavior beyond a basic name.

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 sentence that is concise but under-specified—it merely repeats the SOAP method name without additional context. While it's brief, it fails to provide meaningful information, making it less helpful than it could be for its length.

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 sibling tools and lack of annotations or output schema, the description is incomplete. It does not explain what the tool returns (e.g., grouped data structure) or how it differs from similar tools. For a tool in a rich context with many alternatives, more detail is needed to be fully useful.

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 has 0 parameters with 100% coverage, so no parameter documentation is needed. The description does not add parameter information, which is acceptable here. A baseline of 4 is appropriate as the schema fully covers the lack of parameters.

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 the tool calls a SOAP method named 'ListOfCountryNamesGroupedByContinent', which implies it retrieves country names organized by continent. However, it's vague about the exact purpose—it doesn't specify if it returns a list, map, or structured data, and it doesn't clearly differentiate from siblings like 'ListOfCountryNamesByCode' or 'ListOfContinentsByName'. The description relies on the method name without elaboration.

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. The description does not mention any context, prerequisites, or comparisons to sibling tools such as 'ListOfCountryNamesByCode' or 'FullCountryInfoAllCountries'. Without this, users must infer usage based on the tool name alone.

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