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

The description adds a meaningful behavioral detail beyond the schema: 'No identifiers are retained'. This privacy disclosure is helpful, and the parameter descriptions echo discard semantics. However, with no annotations, the description carries the full burden, and it does not disclose whether the tool performs network calls, has side effects, or what the classification output actually is.

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 concise and front-loaded: 'Show how this request is classified' is the first sentence. There is no filler. The brevity does sacrifice useful context, but as written, every clause earns its place.

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 9 optional parameters, no required fields, no output schema, and no explanation of what the classification result looks like, the description is under-specified. The sibling tool list hints at a routing purpose, but the description never states how to populate the parameters, what the tool returns, or how the result should be used.

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 coverage is 100%, and each parameter already has a concrete description such as 'Git ref name; discarded after the shape check' or 'JSON text to validate; discarded after the check'. The tool description adds no additional parameter-level meaning, so the baseline score 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 specific verb ('Show') and a target ('how this request is classified'), so it is not a pure tautology. However, it never explains what 'compatibility' or 'classification' means, and it does not distinguish this tool from the many sibling lookup/check tools. An agent gets the gist but not the actual classification semantics.

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 on when to use this tool versus alternatives. It does not mention routing to sibling tools, what input should be populated, or when it should be avoided. With 27 sibling tools, the absence of any usage context leaves the agent without clear selection criteria.

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