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

The description offers a privacy note ('No identifiers are retained') but does not explain side effects, return values, error behavior, or whether inputs are consumed. With no annotations, this leaves significant behavioral ambiguity.

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 extremely short and front-loaded, with no redundant phrasing. It loses some points only because the brevity omits necessary operational context.

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?

With nine heterogeneous parameters, no output schema, and no annotations, the description is not complete enough for an agent to know what outcome to expect or how the parameters are used. The classification result is entirely unspecified.

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?

The input schema covers all parameters with per-parameter descriptions, meeting the high-coverage baseline. However, the main description adds no unifying explanation of how the nine unrelated parameters relate to 'classification' or 'compatibility'.

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 states an action ('Show how this request is classified') but does not specify what kind of classification is produced or how 'compatibility' relates to the action. It is too vague to distinguish from other analysis/validation tools in the sibling list.

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 provided about when to use this tool versus the many sibling tools, nor what input conditions are appropriate. An agent cannot determine which scenario should invoke 'compatibility' rather than, for example, 'validate-json' or 'normalize-url'.

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