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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions that identifiers are not retained, but does not state whether the tool is read-only, whether it performs external calls, or what side effects it might have. This is insufficient for an agent to understand the tool's operational behavior.

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 extremely brief, but this brevity is under-specification rather than efficient conciseness. It lacks essential details and does not structure information effectively, so it fails to earn its place as a useful description.

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 accepts nine optional parameters of widely different types, yet the description gives no indication of how they are used, what the tool returns, or how to invoke it correctly. Without an output schema and with such complexity, the description is grossly incomplete and leaves an agent unable to use the tool effectively.

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 each parameter, including notes about discarding and no disk access. The tool description adds no additional parameter semantics, so it relies entirely on the schema. Baseline 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?

The description states a generic action ('show how this request is classified') but fails to specify what kind of classification, what inputs it accepts, or how it differs from the many sibling tools. It is vague and does not convey the tool's specific role, making it hard for an agent to know when to select it.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of conditions, alternatives, or use cases, so an agent has no basis to choose it over the 26 sibling tools.

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