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

With no annotations provided, the description fully bears the behavioral disclosure burden. It does add one meaningful privacy detail—'No identifiers are retained'—but omits other behavioral traits such as side effects, persistence, rate limits, or return shape. This is minimal behavioral context.

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 very short, front-loaded with the main action, and contains no filler. It earns good marks for conciseness, though the brevity borders on under-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?

The tool accepts four heterogeneous optional parameters with no required fields and no output schema, yet the description does not explain how those parameters relate to the classification or what the response will look like. An agent would be guessing about the tool's core behavior.

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 description coverage is 100%, so all four parameters ('url', 'host', 'json', 'zone') are already documented in the schema. The description itself adds no parameter-level meaning, which matches the baseline of 3.

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 says the tool shows how a request is classified, which identifies a verb and a resource at a high level. However, it never specifies what classification dimensions or labels are involved, and it does not distinguish this tool from its siblings such as 'citation', 'common', or 'country'.

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 about when to use this tool versus sibling tools, nor when not to use it. The context of classifying a request is implied but not explicit enough to route an agent correctly among many similar-looking options.

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