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

Since no annotations are provided, the description carries the full disclosure burden. It does disclose a meaningful privacy trait—'No identifiers are retained'—which the parameter descriptions reinforce. However, it does not state whether any external calls occur, what the classification output looks like, or whether there are side effects, so transparency is only partial.

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 only two short sentences with no redundant wording, and the privacy disclaimer earns its place. The first sentence is vague, but the overall text is appropriately compact.

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 annotations, and no output schema, the description is too thin. It does not explain what output the classification produces, how the parameters map to classification outcomes, or how it fits alongside the sibling tools. The schema descriptions help, but the tool-level description leaves critical operational context missing.

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 structured schema already documents all nine optional parameters. The tool description adds no parameter-level meaning beyond the schema, meeting the baseline but not compensating with examples or parameter relationships.

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 an action ('Show') and a resource ('how this request is classified'), so it is not a tautology. However, it never defines what classification categories are produced or what 'request' refers to, leaving the tool's core purpose under-specified. It also does not differentiate itself from the many sibling shape/classification tools.

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 about when to use this tool instead of siblings such as domain-shape, validate-json, or file-path-ok. No alternatives, preconditions, or exclusions are mentioned. Usage is only weakly implied by the verb 'Show'.

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