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

The description discloses one behavioral trait: 'No identifiers are retained', indicating a privacy-preserving behavior. However, with no annotations provided, the description carries the full burden, and it does not clarify whether this is a read-only operation, whether it makes network calls, or how the inputs are processed. This is insufficient for a tool with no annotation support.

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 sentences, concise and front-loaded with the main purpose. However, the brevity contributes to vagueness, and it does not earn its place by adding critical details. It is structured adequately but lacks substance.

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 far from complete. It does not explain what classification output the agent should expect, how to interpret the results, or how the parameters influence the classification. An agent would struggle to use this tool correctly based solely on the description.

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 already provides descriptions for all four parameters (url, host, json, zone) with 100% coverage, so the baseline is 3. The description adds no parameter-specific information, not even how the parameters relate to the classification result. It relies entirely on the schema.

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 the verb 'show' and the resource 'how this request is classified', but it does not specify what classification system or criteria it uses. It fails to distinguish this tool from siblings like validate-json or normalize-url, which also deal with request components. This is clear but vague.

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 mention of when to use this tool versus alternatives. It does not state any conditions, prerequisites, or exclusions. The description gives no guidance on selecting this over sibling tools like citation or domain-shape.

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