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

The description states 'No identifiers are retained,' which is a privacy disclosure, but it does not explain other behaviors such as whether URLs or feeds are fetched, or whether any state is modified. With no annotations, this leaves side effects largely undisclosed.

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 brief and free of fluff, but the brevity comes at the cost of specificity. It is not well-structured enough to communicate the tool's purpose clearly.

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?

The description is incomplete for a tool with nine optional parameters and no output schema. It does not explain what classification is returned, how the parameters are used, or what the expected result looks like.

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%, so the baseline is 3. The tool description itself adds no parameter meaning, but each parameter already has a description in the schema.

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 output is produced. The title 'compatibility' hints at a purpose but does not make it concrete.

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 given about when to use this tool versus any alternative. The sibling tool list is not referenced, and no selection criteria are provided.

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