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

With no annotations, the description carries the full burden of behavioral disclosure. It does add one useful privacy behavior, 'No identifiers are retained,' but it fails to disclose whether inputs are sent externally, whether the call has side effects, what output is produced, or how the classification is computed.

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 two short sentences with no fluff, and the privacy statement earns its place. It is front-loaded with the purpose statement. It is concise, though the brevity comes at the cost of substantive detail.

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?

This is a 9-parameter, no-output-schema tool with no annotations and no usage guidance. The description does not explain what classification means, what the response looks like, whether multiple parameters can be combined, or how to interpret results. It is inadequate for an agent to select and invoke this tool correctly.

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 coverage is 100%, with each of the 9 parameters individually described, so the baseline is 3. The description itself adds no parameter-level meaning, but the schema largely compensates for that gap.

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 'Show how this request is classified,' which identifies a verb and a resource but leaves the classification scheme undefined. It is not a tautology, but it is vague: an agent cannot tell what categories or criteria are involved, nor how this differs from the many sibling tools.

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 given about when to use this tool versus any sibling tool, despite a long list of siblings that appear to correspond to individual input types. The privacy statement says nothing about selection conditions, prerequisites, or alternatives.

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