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

With no annotations, the description must carry the transparency burden. 'No identifiers are retained' is a meaningful privacy disclosure, and some parameter descriptions note 'discarded' or 'no disk access', but the tool's side effects, computational behavior, and result format remain undisclosed.

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 short and the second sentence adds a meaningful privacy note, but the first sentence is ambiguous and wastes the leading position on a vague phrase rather than a specific purpose.

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 diverse optional parameters, no annotations, and many sibling validators, this description is far too sparse. It doesn't state what 'compatibility' means, how inputs are mapped, what the classification output looks like, or when an agent should reach for it.

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 every parameter is already documented. The description adds no additional parameter-level insight beyond the schema, so the baseline of 3 applies.

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 uses a verb ('Show') and a resource ('this request'), but 'how this request is classified' is vague. It does not explain what classifications exist, what output to expect, or how it differs from the many sibling validator 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 versus its alternatives. Null sibling references, no exclusions, and no context about which of the other 28 tools it relates to or supersedes.

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