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

No annotations are present, so the description carries the full behavioral burden. It discloses a meaningful privacy trait ('No identifiers are retained') and the verb 'show' implies a read-only operation, but it does not describe output format, side effects, or errors. This is partial but not full transparency.

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 only two short sentences with no filler, and the main action is front-loaded. The privacy statement earns its place, though the wording is so terse that it under-explains the tool's behavior.

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 seven heterogeneous string parameters, no annotations, and no output schema, the description does not explain what classifications are returned or how the parameters relate to each other. An agent cannot reliably determine the correct parameter choice or interpret the 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?

All seven parameters have descriptions in the input schema, so schema coverage is high and the baseline of 3 applies. The tool description adds no per-parameter meaning and does not clarify whether parameters are exclusive or combined, but the schema already documents each field reasonably well.

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 uses a specific verb ('show') and a resource ('how this request is classified'), but the classification scheme and what constitutes 'this request' are left vague. It does not differentiate the tool from sibling shape/check tools such as 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 alternatives like normalize-url, validate-json, or domain-shape. The privacy statement implies safe handling, but no exclusions or selection criteria are provided.

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