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

With no annotations, the description carries the full behavioral burden, and the only behavioral disclosure is 'No identifiers are retained.' It does not state whether the operation is read-only, whether it has side effects, what happens when multiple parameters are supplied, or how the classification is produced.

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 text is short, readable, and front-loads the core action with no filler. It is under-specified for a nine-parameter tool with no annotations, so the brevity is not fully 'appropriate' even though it is efficient.

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 required fields, no output schema, no annotations, and 27 siblings, but the description does not explain the expected input shape, the output/classification values, or how parameters combine. The privacy note is useful, but the definition is missing significant context an agent would need to invoke it correctly.

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%, and each of the nine parameters has a clear individual description (e.g., 'discarded after the shape check', 'public weather hint'), so the baseline of 3 applies. The tool description adds no interaction semantics, such as whether parameters are alternatives, complements, or mutually exclusive.

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 gives a verb ('Show') and an object ('how this request is classified'), so it is not a pure tautology. However, 'classified' is never defined: an agent does not learn what classification categories exist, what output to expect, or what makes this different from any sibling tool.

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 when-to-use guidance is present, and no alternatives or exclusions are named. The description never connects the request content or parameters to a rule for choosing compatibility over the many sibling tools.

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