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

With no annotations, the description carries the burden of behavioral disclosure. It adds a meaningful privacy guarantee ('No identifiers are retained'), but it does not disclose side effects, external calls, persistence, or what happens to the input beyond retention.

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 very brief and front-loaded with the main purpose. Every sentence contributes, and there is no redundant filler, though the minimalism leaves some aspects under-specified.

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 9 parameters, no annotations, and no output schema, the description is too sparse. It does not explain what 'classified' means, what the output will look like, which parameters should be provided, or how this relates to sibling tools. The schema helps with individual parameters, but the overall tool behavior remains unclear.

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 parameter is documented with meaningful context such as 'discarded after the shape check' or 'public weather hint.' The tool description itself adds no parameter-specific meaning, so the baseline 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 clearly states a verb and object: 'Show how this request is classified.' It is specific enough to indicate the tool's core function, but it does not mention what classification system is used or how it differs from sibling tools like domain-shape or file-path-ok.

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 versus alternatives. No exclusions, prerequisites, or sibling routing are mentioned, so an agent must infer usage from the vague phrase 'this request.'

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