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

With no annotations, the description carries the full burden of behavioral disclosure. It does disclose that no identifiers are retained, which is useful privacy context, but it does not mention side effects, whether external requests are made, authentication needs, or what happens to the provided inputs beyond the schema-level 'discarded' notes.

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 short and front-loaded, with no wasted words. However, for a tool with 9 parameters and no output schema, it is under-specified rather than efficiently complete.

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, missing annotations, and lack of an output schema, the description should explain what the classification result looks like and how the multiple inputs are used. It does not, leaving substantial gaps for an agent trying to invoke or interpret 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 the schema already documents every parameter. The description itself adds no additional meaning about how parameters relate to the classification, so the baseline score of 3 is appropriate.

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?

'Show how this request is classified' identifies a verb and a vague object, but it does not specify what classification scheme is used, what categories exist, or what counts as 'this request.' It is not a tautology, but it lacks enough specificity to clearly distinguish the tool from several classification-like siblings.

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 about when to use this tool versus alternatives, and no exclusions or preferred contexts. An agent cannot determine whether this should be chosen over validate-json, normalize-url, domain-shape, or other sibling tools.

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