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

The only behavioral claim is 'No identifiers are retained,' which addresses privacy but not what the tool actually does with inputs, whether it accesses external resources, or what side effects may occur. With no annotations, the description carries the full burden and falls short.

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 short and contains no filler or redundant phrases. Both sentences provide some information, but the extreme brevity contributes to ambiguity even though the structure itself is efficient.

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 output schema, and no annotations, the description is far too incomplete. It never explains what 'classified' means, what output the agent should expect, or how the many parameters relate to the tool's purpose.

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 description itself adds no parameter-level meaning beyond the input schema. However, schema description coverage is 100%, so the baseline of 3 applies even though the tool description does not clarify how each parameter contributes to classification.

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 says 'Show how this request is classified' but never defines what classification means or what compatibility refers to. It lacks a clear resource or outcome, and does not distinguish the tool from siblings like fetch-status or validate-json.

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 any alternative. The description provides no conditions, use cases, or examples, so an agent cannot determine when compatibility should be invoked.

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