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

With no annotations, the description carries the behavioral disclosure burden. It does add one meaningful trait: 'No identifiers are retained.' However, it does not state what side effects may occur, whether network access happens, what the returned classification looks like, or how the request is otherwise processed.

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 sentences with no wasted words, and the core idea is front-loaded. However, the first sentence is vague enough that the conciseness comes at the cost of useful content.

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?

This tool has nine optional parameters, no annotations, and no output schema, yet the description does not explain the classification categories, the expected output, or how the tool relates to the extensive sibling list. The privacy note is useful but insufficient for an agent to invoke this 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 the schema already documents every parameter. The main description adds no parameter-level meaning, but it does not need to because the schema descriptions are clear and specify the role of each input.

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 a verb and object ('Show how this request is classified'), so it is not a pure tautology, but the classification scheme is unexplained. It does not distinguish this tool from its many siblings or indicate what 'compatibility' means.

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 the sibling tools, nor when not to use it. The parameter schema hints at different input categories, but the description itself provides no routing or alternative selection advice.

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