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

With no annotations provided, the description carries the full behavioral burden. It does disclose one meaningful trait—'No identifiers are retained'—which signals privacy-conscious handling, but it never states whether the tool is read-only, what output is produced, or what side effects or logging behavior might occur.

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, no filler, and the primary action is front-loaded. The privacy note earns its place as the only behavioral disclosure. Nothing here is redundant.

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?

Despite low structural complexity, the tool has no output schema and the description does not explain what 'classified' means, what the return value looks like, or how the optional parameters influence the result. An agent would not know what to expect after invoking it.

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 schema already documents all four parameters clearly. The description adds no additional meaning about how url, host, json, or zone relate to the classification, so the baseline 3 is appropriate.

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 an action ('Show how this request is classified') but never says what 'classified' means, what categories or dimensions are involved, or what the tool is actually for. It is vague rather than tautological, and does not meaningfully distinguish this tool from its siblings like 'citation' 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 alternatives, no prerequisites, and no exclusions. The only implicit context is that it accepts some kind of request data, but the description does not explain what problem it solves or when an agent should reach for it.

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