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

Annotations are absent, but the description explicitly discloses a key behavioral trait: no identifiers are retained. This is very useful for privacy/security considerations. However, it doesn't describe the response format or any other side effects; for a classification tool, this might be enough.

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?

Two short sentences, no fluff, and the most important behavioral constraint ('No identifiers are retained') is stated. Perfectly sized.

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?

For a classification tool with 4 optional parameters and no output schema, the description is adequate. It could benefit from saying what the output looks like (e.g., a classification label) or providing an example, but given the schema already documents all parameters, this is a marginal gap.

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 all four parameters. The description doesn't add additional meaning to the parameters. 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 is clear and concise: it says what the tool does ('Show how this request is classified') and explicitly states a critical behavioral constraint: 'No identifiers are retained.' This distinguishes it from tools that might store or use request data.

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 doesn't provide guidance on when to use this tool vs alternatives. It doesn't say when to use it (e.g., 'for classification of a request') nor when not to use it. The context is implied but not explicit.

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