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

With no annotations, the description carries the full burden of explaining side effects and data handling. It does add a meaningful privacy guarantee ('No identifiers are retained') and the verb 'Show' implies a read-only operation, but it omits details about external calls, output format, or any other behavioral effects.

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 the primary action front-loaded and the privacy guarantee in the second sentence. There is no filler or redundant restatement; every word earns its place.

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?

The tool has 9 heterogeneous parameters, no output schema, and no annotations, so the description must explain what the classification output looks like and how the parameters are used. It does neither. An agent cannot reliably predict the result or know how to invoke the tool correctly.

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 every parameter already has a description in the schema. The tool description itself adds no parameter-level meaning, which is acceptable given the high coverage and yields the baseline score of 3.

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 an action ('Show') and a subject ('how this request is classified'), but 'classified' is never defined. It does not say what kind of classification is being produced, what categories exist, or how it differs from numerous sibling classifier tools like domain-shape, github-repo-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 27 sibling tools. The privacy note is useful, but it does not help an agent decide when to call compatibility rather than normalize-url, validate-json, file-path-ok, or the others.

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