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

No annotations exist, so the description has the full burden. 'No identifiers are retained' is a real behavioral disclosure that adds light privacy and processing semantics, supplementing the schema's 'discarded' hints. However it remains silent about side effects, whether the request is merely inspected, and what the response contains.

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?

Two short sentences are front-loaded and waste no words: purpose first, privacy note second. It is concise to the point of being terse, but under the 10% weight, the structure itself earns credit.

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?

A 9-parameter, requiredless tool with no output schema and no annotations needs much more than this. The description does not explain how inputs are classified, what result is returned, or how the parameters combine. This is an inadequate specification for an agent to reason about invocation confidently.

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% (9/9 parameters have descriptions), so the baseline is 3. The description adds no parameter-level information beyond the schema, and its 'No identifiers are retained' line just restates what schema descriptions already imply for several parameters.

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 phrase 'Show how this request is classified' uses a verb but the object is vague and no resource is named. It does not distinguish the tool from its many specific siblings like validate-json or fetch-browser-status, or even explain how it relates to its name. It is more than a bare tautology but still too fuzzy to select reliably.

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?

The description offers no when/when-not/alternatives. With 28 sibling tools, no mention of which case this dispatch/classification tool should be preferred over a dedicated validator leaves an agent guessing. There is no guidance to exclude or include.

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