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

With no annotations, the description carries the full burden of behavioral disclosure. It adds one useful privacy statement, 'No identifiers are retained,' but does not explain what the tool does beyond classification, whether it makes external calls, or what side effects, if any, exist.

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 two sentences are tight, front-loaded, and contain no fluff; the purpose statement comes first and the privacy note second. It is perhaps too terse to be fully useful, but structurally it is concise.

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 optional parameters, no output schema, and no annotations, so the description must carry substantial context. It fails to state what classification outputs look like, how parameters map to classifications, or when this tool should be invoked, leaving an agent under-informed.

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 coverage is 100%, so all nine parameters already have meaningful descriptions. The tool description adds only a general retention guarantee and no per-parameter meaning, which matches the baseline for high schema coverage.

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,' which conveys a classification/shape-checking purpose but leaves the classification scheme undefined. It does not distinguish this tool from its many siblings, making the purpose only minimally clear.

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?

No guidance is given about when to use this tool versus alternatives such as normalize-url, validate-json, or file-path-ok. The description provides neither explicit when/when-not conditions nor references to sibling tools.

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