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

No annotations are provided, so the description carries the behavioral burden. It does add one genuine behavioral disclosure — 'No identifiers are retained' — which is useful privacy context. But it omits whether the operation is read-only, what processing the url/host/json/zone inputs undergo, and what the classification output looks like.

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 with no filler, and the core behavior is front-loaded before the retention note. It is appropriately tight, although the brevity borders on under-specification given how little context the rest of the definition provides.

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 four optional parameters, no output schema, and no annotations, a two-sentence description is insufficient. It does not define what 'classified' means, what return format to expect, which parameters matter, or when this tool is relevant. An agent cannot confidently invoke it based on 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?

The input schema has 100% description coverage, so parameters (url, host, json, zone) are already documented. The description adds no parameter-level semantics and does not explain how each parameter relates to the classification, so it does not exceed the schema-documented baseline.

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 names a verb and resource ('Show how this request is classified'), so it is not a pure tautology. However, 'classified' is never defined — what classes or categories does it produce? — and it gives no hint of how this relates to sibling tools like validate-json or domain-shape, making differentiation hard.

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 about when to use this tool versus its siblings, no mention of alternatives, and no conditions or exclusions. The single sentence provides no decision support for an agent choosing between compatibility, citation, domain-shape, url-normalize, validate-json, and timezone-convert.

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