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

The description discloses that identifiers are not retained, which is a useful privacy note, but it does not explain whether the tool makes network calls, accesses files, or performs any other side effects. With no annotations, the behavioral disclosure is incomplete.

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 uses no unnecessary words, but it is too terse to be well-structured or informative. It reads as a single vague sentence rather than a properly organized tool 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 has nine varied optional parameters, no output schema, and no annotations, yet the description provides almost no context about its purpose, classification logic, or expected behavior. It is not complete enough for an agent to know when or how to call it.

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 schema already provides 100% description coverage for all nine parameters, each with a clear one-line meaning. The tool description adds no extra parameter semantics beyond the schema, 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?

The description says the tool will 'Show how this request is classified,' but it never defines what 'compatibility' means, what classification categories exist, or what the output will look like. The purpose is too vague to distinguish from other tools, and the name alone does not clarify the behavior.

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?

There is no guidance on when to use this tool instead of one of the many siblings. It does not mention whether it should be used for routing, validation, or something else, nor does it indicate prerequisites or expected input patterns.

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