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

With no annotations, the description must carry the burden of explaining side effects, data handling, or other behaviors. The only behavioral note is 'No identifiers are retained,' which is a privacy statement but does not clarify the actual processing, side effects, or what happens to the input beyond that.

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 free of unnecessary words, which is structurally concise. However, the primary sentence is so vague that it does not effectively communicate the tool's purpose, and the second sentence is a tangential privacy note. While not verbose, it fails to be usefully clear.

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 9 optional parameters and no output schema, making it inherently complex. The description is far too sparse to explain what kinds of inputs are compatible, what 'classified' means, what the tool returns, or how it relates to the sibling tools. This is a significant gap that prevents an agent from using 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?

The input schema covers all 9 parameters with individual descriptions, so the schema itself provides semantic hints. However, the tool description adds no additional meaning about how these parameters relate to the classification task, leaving the agent to infer from the schema descriptions alone. Since coverage is high, the baseline 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?

The description 'Show how this request is classified' is extremely vague and does not specify what kind of classification is performed, on what resource, or what the output would be. It fails to name a concrete action or object, making it impossible to understand the tool's purpose without additional context.

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 the many sibling tools. It does not mention any alternatives, criteria, or conditions that would help an agent decide to invoke this tool instead of others.

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