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

The description and parameter annotations state that identifiers are not retained and data is 'discarded' or 'no disk access', which partially discloses non-persistence. However, it does not explain what the tool actually does with the inputs, so the behavioral impact remains unclear.

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 brief and lacks substance. While short and to the point, it omits critical information, making it ineffective despite its conciseness.

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 parameters and no output schema, the description is drastically incomplete. It does not explain what the tool returns, how the parameters relate, or what 'compatibility' refers to. The context is wholly insufficient for an agent to use it correctly.

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?

While each of the 9 parameters has a description, the descriptions are inconsistent and do not form a coherent picture (e.g., 'public weather hint', 'titles discarded'). They hint at checking shapes or lengths but never explain the overall purpose, so the semantics remain confusing.

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 'Show how this request is classified' is vague and does not explain what 'compatibility' means or what specific action the tool performs. It lacks a clear verb-resource relationship, making it impossible to distinguish from other 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?

No guidance is provided on when to use this tool versus any of the 26 sibling tools. There is no mention of conditions, alternatives, or typical use cases.

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