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

With no annotations, the description must carry the burden of explaining side effects, privacy, and limitations. It only says 'No identifiers are retained' and mentions values being 'discarded', but does not explain what processing occurs, whether external calls are made, or what the output represents.

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 short but not effective: it lacks essential details while using ambiguous phrasing. It is concise in word count but not in conveying actionable meaning.

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?

There is no output schema, no examples, no explanation of classification outcomes, and no indication of how the parameters are used together. With nine optional parameters and no required ones, the tool is highly underspecified for an agent to invoke 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?

Schema descriptions cover all parameters at a surface level, but the meanings are cryptic and disconnected from the stated purpose. For example, 'City name for a public weather hint; discarded after the call' does not clarify how it contributes to classification. The relationship among the nine optional parameters is unexplained.

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 specifies what classification means, what categories are produced, or how the tool relates to its name 'compatibility'. It is too vague for an agent to know what this tool actually does.

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 any of the many sibling tools. The description does not mention alternatives, preconditions, or selection criteria, leaving the agent to guess.

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