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

With no annotations provided, the description carries full burden for behavioral disclosure but fails completely. It doesn't indicate whether this is a read or write operation, what authentication might be required, error conditions, rate limits, or what format the response takes. The SOAP protocol mention is technical but doesn't describe the tool's actual 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?

The description is extremely concise (just 4 words), but this brevity comes at the cost of being under-specified rather than efficiently informative. While it's technically front-loaded (the entire description is one short phrase), it doesn't contain enough substance to be considered well-structured for tool selection.

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?

For a tool with no annotations, no output schema, and 0% schema description coverage, the description is completely inadequate. It doesn't explain what the tool does, when to use it, what parameters mean, or what to expect in return. Given the complexity implied by the SOAP protocol and the rich sibling tool ecosystem, this description leaves the agent with almost no useful information.

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 0% description coverage, so the single parameter 'sCountryName' is completely undocumented in the schema. The description provides no information about this parameter - no explanation of what format the country name should be in, whether it accepts partial names, case sensitivity, or examples. The description fails to compensate for the schema's lack of 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 'SOAP method: CountryISOCode' is tautological - it essentially restates the tool name with technical protocol information. It doesn't specify what the tool actually does (e.g., 'Returns ISO country code for a given country name'). While it mentions SOAP method context, this doesn't clarify the tool's functional purpose beyond its name.

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 provides absolutely no guidance about when to use this tool versus the many sibling tools available (like CountryName, CountryCurrency, FullCountryInfo, etc.). There's no indication of what problem this tool solves or what context would make it the appropriate choice among the 20+ country-related tools.

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