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

No annotations exist, so the description carries the transparency burden. It adds one meaningful behavioral guarantee—'No identifiers are retained'—but says nothing about execution side effects, whether the input is sent elsewhere, or what the classification output contains.

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 short sentences deliver the core purpose and the privacy guarantee with no filler. The main action is front-loaded and the secondary note is separate but relevant.

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 and nine optional parameters, the description is too thin: it does not explain what the classification returns, how to choose among the parameters, or how to interpret the result. An agent cannot confidently map a request to the correct call from this definition alone.

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 the input schema already documents all nine parameters. The tool description adds no additional parameter meaning beyond the schema.

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 a verb and resource ('Show how this request is classified') but leaves the classification scheme unspecified; it never says what categories or kinds of compatibility are being reported. This is clearer than a tautology but too vague to distinguish from the many sibling tools without inspecting the schema.

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?

There is no guidance on when to call this tool instead of a sibling such as normalize-url, validate-json, or geo-hint. The description implies a classification/checking role but never states the triggering condition or what to do with the result.

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