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

The description does disclose a meaningful behavior: identifiers are not retained. This is valuable because no annotations are provided. However, it does not state whether the operation is read-only, what output or return values look like, whether external calls are made, or how multiple parameters are handled, leaving the tool's overall behavior under-specified.

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 one short, front-loaded sentence with no filler. It states the core action and a key constraint efficiently, and every word contributes meaning.

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 annotations, no output schema, and nine heterogeneous optional parameters, the description is too sparse. It never explains what 'classified' means, what the output looks like, or when to select this tool over its siblings, so an agent cannot confidently predict the tool's behavior or result.

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 baseline is 3. The description adds no parameter-level detail, but the schema already documents each parameter and its discard behavior; the 'No identifiers retained' sentence is a general guarantee that paraphrases the schema rather than replacing it.

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 ('Show') and an object ('classification of this request'), so it is not a tautology. However, 'classification' is vague: it does not specify what categories are returned, what 'this request' refers to, or how this differs from sibling classification/shape tools like domain-shape or validate-json.

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 the many sibling tools. The only additional statement, 'No identifiers are retained,' is a privacy guarantee rather than a usage condition, and no alternatives or exclusions are mentioned.

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