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

With no annotations, the description carries the behavioral burden. It does contribute a meaningful behavioral fact: 'No identifiers are retained.' It also implies a read-only operation via 'Show', which is useful. However, it does not clarify whether the input is processed, discarded, logged, or what side effects might occur beyond identifier retention.

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 brief and front-loaded with the primary action, followed by a useful privacy caveat. No filler is present, though the terseness contributes to under-specification in other dimensions.

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 four optional parameters, no output schema, and no annotations, so the description needs to carry substantial contextual weight. It does not explain what 'classification' means, what the result looks like, or how the parameters affect the call, leaving an agent without enough context to invoke it confidently.

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%, and each parameter has its own description, so the schema already documents individual parameters. The tool description adds no further parameter-level meaning, such as how url, host, json, and zone relate to the classification outcome.

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 defines what 'request', 'classified', or 'compatibility' mean, or what classification categories are returned. It is not a tautology, but it is too vague to give an agent a concrete model of the operation.

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?

No guidance is given about when to use this tool versus any sibling, or what kind of input should be passed when. The phrase 'No identifiers are retained' hints at a privacy-oriented use case, but it does not specify conditions for selection or exclusions.

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