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

The description states 'No identifiers are retained,' which is a useful privacy note, and some parameter descriptions mention 'discarded' or 'no disk access.' However, there are no annotations and no explanation of broader side effects, return behavior, or whether any network/file access occurs.

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 and parameter descriptions are compact and free of redundant text. The main description is a single short sentence, and each parameter is explained in one concise line.

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 the tool's complexity—nine optional parameters, no output schema, and no annotations—the description is not complete. It omits what the classification result looks like, how parameters are used together, and any prerequisites or limitations beyond scattered per-parameter notes.

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 nine parameters have individual one-line descriptions, and several indicate discard/no-access behavior, but the descriptions are not tied to a coherent purpose. The relationships between parameters and the tool's classification behavior remain unexplained, so the meaning is only partially conveyed.

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 'Show how this request is classified' is too vague to indicate what the tool actually does or what resource it acts on. The name 'compatibility' and the nine unrelated parameters do not clarify the intended operation, and no sibling differentiation is provided.

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?

The description gives no guidance on when to use this tool instead of any of the many sibling tools. There is no mention of alternatives, conditions, or decision criteria, leaving an agent unable to choose appropriately.

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