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

With no annotations provided, the description carries the full behavioral burden. It does disclose that identifiers are not retained, which is useful, but it does not say whether the operation is read-only, what side effects exist, what happens to the provided inputs, or what the output looks like. The schema-level 'discarded' notes are outside the tool description itself.

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 compact and front-loaded, with the core purpose stated before the privacy note. Both sentences are short and avoid unnecessary detail, though the first sentence is vague enough to limit its usefulness.

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 tool with nine optional parameters, no required parameters, no output schema, and a large cluster of similar siblings, this description is incomplete. An agent cannot determine what to pass, what the classification result will be, or when this tool is preferable to alternatives.

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 the meaning of all nine optional parameters. The tool description adds no parameter-level guidance and does not clarify which, if any, parameters should be provided together.

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 clear verb and object ('Show how this request is classified'), but it never explains what 'classified' means, what categories exist, or how the tool relates to its many similar siblings. This is more than a tautology, but too vague for an agent to reliably know what this tool returns.

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 the many sibling tools with overlapping input shapes (URLs, refs, paths, timezones, queries). The privacy note is not a usage guideline, and no alternatives or exclusions are mentioned.

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