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 'No identifiers are retained,' which addresses privacy but omits whether this is a read-only operation, what side effects occur, or how the classification is performed. The description is insufficiently transparent.

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 (one sentence) but lacks structure and key details. It is under-specified rather than concise; the statement does not organize information or highlight what an agent needs to know.

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 four optional parameters, no output schema, and no annotations, the description is grossly incomplete. It does not explain what classification means, how the parameters influence the result, or what the response looks like. An agent would have to guess at the tool's 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?

The input schema documents each parameter with 100% coverage, so the baseline is 3. The description adds no meaning beyond the schema—it never references the four parameters or how they relate to classification. It does not compensate for any gaps, but the schema already handles parameter 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 'Show how this request is classified' is vague about what classification means and does not specify the resource or scope. It does not differentiate from sibling tools like citation or validate-json, leaving the agent unsure what input is expected or what output is produced.

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 use this tool versus alternatives. The description does not mention any conditions, exclusions, or sibling tools, so an agent cannot decide when this tool is appropriate.

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